All-In-One Suspension System
When towing or hauling a heavy load, you may encounter a number of problems that can make your driving experience difficult or dangerous, such as sway, body roll, or bottoming out. When your vehicle is weighted down, your factory leaf springs can't counteract these problems to the extent that they are supposed to. The weight will overpower the leaf springs and cause them to twist or flatten out. When that happens, they cannot support, level, or stabilize your vehicle effectively. Additionally, because your factory leaf springs are passive, they won't begin to tackle problems such as sway until those problems have already started.
RoadActive Suspension (RAS) kits enhance those passive leaf springs by converting them into a mechanically active, all-in-one suspension system. RAS kits have variable-rated coil tension springs that automatically adjust to your heavy load. Other suspension systems only solve a few problems and usually at the expense of other improvements your factory leaf springs may need. RAS, on the other hand, is a unique kit that provides everything you want in a suspension system without any trade-offs. It eliminates bottoming out like air springs, reduces sway and body roll like sway bars, keeps your ride level like helper springs, and improves traction and braking control like traction bars. This improves your vehicle's stability, handling, and control while you are towing or hauling, as well as when your vehicle is unloaded. RAS also makes your overall driving and towing experience safer and more comfortable, which greatly lessens driver fatigue.
How RAS Works
Each RAS unit has a powerful variable-rated coil tension spring that converts your passive leaf spring into a mechanically-active system. Once your vehicle is loaded, the tension springs immediately activate to absorb and support the weight. This allows your leaf springs to maintain their bowed position and keeps them from flattening out or flipping over, which greatly hinders their ability to bear a heavy load. The tension springs are variable-rated, which means that the heavier your load is, the more assistance they provide to your leaf springs. Because of this design, RAS reacts instantaneously, whereas hydraulics, air springs, and other suspension systems take time to react. And unlike your factory leaf springs, RAS stops sway and sag before they even start to happen. Additionally, when your vehicle is unloaded, the tension springs disengage, allowing your leaf springs to perform as intended without hardening your ride. RAS won't hinder your leaf springs' movement, nor will it cause any friction between any of the brackets.
Eliminates Axle Wrap and Wheel Hop
When under a heavy load, leaf springs are especially susceptible to axle wrap, which can cause wheel hop. Wheel hop is when the tires lose their grip on the road, causing a jarring, up-and-down movement. Axle wrap occurs when the circular motion of the tires cause the leaf springs to twist or rotate. If the leaf springs twist far enough, wheel hop can occur. RAS stabilizes your leaf springs by absorbing the force of the load they're trying to support. This eliminates axle wrap and wheel hop, as well as prevents your vehicle from bottoming out. Because of this, less strain is put on your vehicle. And by reducing some of this wear and tear, RAS helps extend the life of your leaf springs, shock absorbers, shackles, and even tires.
Reduces Sway and Body Roll
When driving along a curve while towing or hauling a heavy load, the back end of your vehicle or trailer can start to shift with that weight. If your factory leaf springs have flattened or twisted under this load, they won't be able to prevent it from shifting. Because of this, your trailer will sway away from your vehicle. This makes driving challenging and dangerous, as it increases the risk of body roll, which is when your vehicle drastically leans to one side. This can often cause you to completely lose control of your vehicle. Body roll is especially prevalent with multi-passenger vans and vehicles towing long campers, trailers, or boats. RAS provides a much safer ride by reinforcing your factory leaf springs and stabilizing your load. This helps prevent sway from occurring and reduces the chance of body roll while cornering, turning, and swerving. RAS also lessens the rocking motion that happens during windy conditions or when a semi passes by on the road.
Levels Your Ride and Improves Traction
When your vehicle is overloaded, the bulk of the weight transfers to the rear axle. Your factory leaf springs then become overwhelmed by this weight, as they are not strong enough to support it. This causes the back end of your vehicle to sag and the front end to rise, which means that the front tires have lost some of the grip they need with the road. In addition to loss of traction, it can also cause poor headlight aim, unintentional swerving, and an extremely bumpy and uncomfortable ride. RAS bolsters your factory leaf springs and enables them to provide support for your load without compromising ride quality or comfort. This keeps your ride level from front to back whether you are hauling a load in the bed or towing a boat, trailer, or camper. RAS also ensures that your tires have the traction they require while braking and accelerating, which improves the overall driving experience.
Customizable Coil Tension Springs
RAS is also customizable. During installation, the coil tension springs can be adjusted to 2 different tension settings or anywhere in between for improved road handling and support. To do this, rotate the springs while keeping the threaded rod still. As you turn the spring, use one of the 2 included spacers as a gauge to measure the widening gaps between the coils. In order for the RAS units to work as intended, you must tension the coils to a minimum of 25 percent with the 1mm white spacer and no more than 40 percent with the 2mm spacer. The springs can also be independently adjusted to compensate for off-center loads such as a handicap lift.
Easy, Bolt-On Installation
This custom-fit kit comes fully assembled and is easy to install. Each RAS unit simply bolts onto your factory leaf spring with the included hardware, and drilling, welding, and cutting aren't required. First, position the eye hook bracket so that it wraps around the top of the factory leaf spring eye. Then the axle bracket secures under the leaf spring and around the factory U-bolts on the other side of the leaf spring pack. Once the maintenance-free RAS units are fully installed, you won't need to monitor them as you would with air springs.
Corrosion-Resistant Steel Construction
RAS is extremely durable and corrosion-resistant. The units are constructed of high-grade alloy steel, and they have an epoxy e-coat on the coil springs to provide extreme corrosion resistance. The brackets on the ends of each unit resist the effects of water and other elements, and they have a salt spray rating of more than 800 hours.

I bought this last summer (2022) for my 2020 F150 to haul the travel trailer (summer) and to have the quad in the box (fall) during the hunting season. I mainly used it during the weekends as I work from home during the weekdays. I adjusted the tension just before the winter because I haven't haul anything during winter. As it is now spring, I wanted to adjust back the tension for the rv season and I found everything rusted out (I am.in Canada and use the truck only 2-3 times a week).
I was pleased to use the product back last summer but because of all the rust I found this spring, I'm having a hard time adjusting them and I am also quite scared for next seasons as rust is making adjustments hard.
By having this for less than a year, I am now dissapointed in the product. Before buying this, I looked a lot into airlift a lot but because of reviews, I changed my mind to go with RAS.
Rust is now found on the main threaded rod locking nuts the bolt/tube underneat locking the device was rusted and seized.

2023 Dodge Ram Pickup
Installed this today on my 2023 Ford F150 Lariat 4x4 with the tow package. The kit arrived within 2 days of ordering. The box was slightly open but the springs appeared undamaged. I elected to do the install myself and opted to get a 4 ton floor jack to replace my very old 3 ton. I’m very glad I did. After blocking the front tires and setting the parking brake, I loosened the wheels and raised the rear at the differential using a small 2x4 block to span the contact points. I took the wheels off and originally set my jack stands in front of the leaf spring on the frame. Lowering the truck onto the stands was not effective. There wasn’t enough travel to provide relief to the springs. I ended up setting my jack stands on some 1x16 scrap pieces and put them under the spring attachment point. This gave me just enough room on my floor jack to unburden the springs. Once I got over this small hurdle the install went smoothly. This took about an hour to very carefully construct as I didn’t want to drop my brand new truck on the ground. Brand new 5 ton jack stands would have eased my mind considerably. My install includes a spacer for the bump stop to offset it towards the centerline of the vehicle. The instructions weren’t intuitive and it took a few minutes to figure out the bolts. You need to insert the provided bolt into the spacer and attach the spacer to the frame with the original bump stop bolt. It’s the only one you can get a socket on in the depression. The bump stop then attaches to the provided bolt you inserted into the spacer using the provided nut. You will need a deep well 15mm socket for this attachment. Fortunately I had one. I set the spring using the 25% white spacer, reinstalled the wheels and set the truck back on the deck. The truck now sits 3/4” higher in the rear. I drove around and noticed that I was sitting a little higher as the site picture changed a bit. The truck didn’t seem to ride differently empty. If anything it seemed a little more cushioned though no less responsive. I towed my 9000lb travel trailer previously with a Ram 2500 6.7l diesel that had Sumo springs and a WD hitch. I got tired of the cost and maintenance and selected this Ford because it could haul the trailer. I chose the RAS over the Sumo springs because of how much squat I observed when I hooked up the trailer initially. I will update after I tow the trailer. My only concern at the moment is that the bump stop spacer isn’t going to provide enough clearance from the bracket.

Follow up to my earlier review.
On top of the excellent care and service from etrailer, the roadmaster active suspension was easy to install. My Travel Trailer has a 1200lb hitch weight so I used the black spacer. The RAS gave my truck a 1 1/2” lift. I had recently loaded my truck to the top of the sidewalls with wood for the winter. Barely put a squat in the suspension. The truck handled on the highway like it had a quarter the weight. There was no noticeable sway or body roll. Unloaded the truck handles better than it did with just the leaf springs. Does not feel like hockey puck suspension. Love the RAS kit. My truck is a 2018 Ford F-150 eco boost with the max tow package. Looking forward to hooking up the Travel Trailer this fall.

So it has been a little over a year since I had installed the RAS kit on my 2018 Ford F150 3.5l eco boost with max tow package and 3:55 rear end. I have towed my 2022 34’ Jayco trailer a couple of times. The truck is rated to tow 11,500lbs and has a cargo capacity of 1,700lbs. Trailer loaded is 9,283lbs with 1,124lbs on the hitch. I tow with a trunion style weight distribution and sway control set up. When the trailer is hooked up both axles have the weight evenly distributed. The RAS coils control the body sway of the truck making the setup feel like a 5th wheel tow. I had towed the trailer on the 400 series highwayexpressway. At 100 to 110kmhr with transport trucks and a decent cross wind my truck and trailer were easy to keep in the lane. There was no noticeable sway as the truck and trailer moved in unison when hit with the cross wind or the vortex created by passing transport trucks. The truck and trailer weren’t even affected by the troughs in the highway. Love the RAS kit. Has added stability to my setup and has helped to make the towing experience more comfortable.

@Jeff That's awesome to hear, we're glad to hear everything's working well for you. Having a properly handling trailer is crucial to a good towing experience!

Roadmaster active suspension seems to be built very well. I look forward to towing my travel trailer very soon to see if it improves the towing experience.

It has been a year now since I installed the Roadmaster Active Suspension system on my 2018 F150. We pull a 30 ft travel trailer from Wisconsin to Alabama.Last year the roads became very slippery when we encountered a rain snow mix. The truck and trailer tracked perfectly. I just hooked up the rig yesterday to take the same trip, leaving tomorrow. The truck definitely handles better with the RAS. Im glad I installed it and am sure it will last for years.

I have a 2020 Ford F150 and purchased this product because I bought a 33’ 5th Wheel Trailer and wanted to add the additional suspension. It has more than surpassed my expectation. By adding this, I have be able to keep the front and rear bumpers to a difference of 1/2” and my truck runs very smooth. This product lives up to it claim and was well worth the money.
by: Ken02/16/2021
etrailer asked if I would review the roadmaster active suspension kit after a year. Ok, I get a lot of junk email but this impressed me. This shows that they are a stand up company.
I purchased this product to help with the sag I was getting at the hitch.
I read a lot of articles and literature about the sagging issues and almost went with an air system as they are described as the end all be all fix. WRONG!
I installed this RAS on my 2018 F150 and the sag was gone. It has never returned. The trailer rides true behind my truck and my truck rides great when I’m not hooked up.
I have max towing capability with my truck from the factory but I pull a 10,000 lb trailer. Lot of concrete grinding equipment, big vacs, generator and I haven’t had any issues at all.
The Roadmaster active suspension works just as advertised. I’m very happy with the purchase and I’ll do it again on my next truck.

Wait what?!
Should’ve put these on first thing when I got the truck. Raised the rear a little over an inch, unloaded ride improves, and now tows level! No messing with air hoses, or pumping them up, just install and Tighten! Reminds me of accumulators on hydraulic setups, brilliant idea

A year later and they still work great! It’s impressive how improved the handling in our 2013 Ford F-150 FX4 even without our 30ft camper on the back. No more spinning shale going up our driveway or sway on highway, these give it a much more planted stance in all applications. Hauling our camper without a major squat or hitting the bump pads is achievable with these units! You will not regret this purchase! I installed them on my own, in my garage along with new Bilstine shocks I purchased online in less than an hour! Great instructional YouTube videos showing proper install. Not a mechanic at all, I work in Sales for ADT Security and drive over 4,000 miles a month.

Two years after install and it’s still great, looks like new after 3 long PA Winters! General daily use even while not towing still makes handling much more improved over stock OEM. Currently have a 2013 F150 3.5 EcoBoost with 186,000 miles. Plan on taking our camper from PA to Nantucket this summer, this wouldn’t be possible without the Roadmaster Active Suspension!
by: Greg05/05/2023
Shipping was fast. The product is heavy metal pieces with a thin box. Mine came delivered all beat up and end of box was wide open and parts can easily fall out. I have purchased many items from trailer and this is first time box was in this condition. I think I got lucky and all parts are there.

I don’t normally post about items I have purchased, but in this case, I had to make an exception. I did a lot of research on helper springs and ways to insure my truck gave me my maximum rating. We purchased this kit and it actually arrived a day early and best of all, the day before we were going to get our new 5th-wheel trailer. My son-in-law helped me install them in under an hour. Unfortunately, I did not measure my height before the install, but it did look like it raised the truck a small amount but that was fine with me. I didn’t notice any difference in the ride. The next day we picked up our new Reflection 150 - 278BH trailer. When we first connected the trailer, the maintenance manager commented “Wow, I really expected to see the back end of the truck drop more”. I told him I had installed this kit and he was very impressed. We had a cold front pushing through and had a 20-25 mph crosswind hitting our new rig as we drove home. Since I had not pulled this rig before, I was a little concerned about how the truck would handle. All-in-all, it handled great and the truck felt secure on the road. You could still feel the wind at times, but I did not feel like the truck swayed as much as I remembered our old truck and trailer. Overall, I am quite happy with this kit. My wife said she didn’t really notice any difference in the ride but she did say she thought our truck now looked a little jacked up without the trailer, but as I said, that’s fine with me.

Installed this evening on my 2019 F150 FX4 Crew Cab 5.5 ft bed. On level-ish ground before install the fender well was 39.5 inches from the ground (unloaded). Installed these and set the tension for a 2mm gap with the black spacer in the kit for a 40% increase..... This kit removed a little squat and the fender is now 40.25 inches from the ground (unloaded). Truck rides good unloaded, have not yet pulled the travel trailer with them installed. I will update the next time I tow something heavy that I've towed with this truck before installing these. To set the tension use a 9/16 wrench or socket. The bolt is actuall made for an allen wrench but roadmaster uses silicon to glue what apears to be part of an allen wrench into the bolt. I understand this makes it easier for us to install, but they should use something stronger than silicon as one of mine fell out as soon as I started turning it. See pictures.

I tow a 31 foot trailer with my 1/2 ton. Before adding this product the sway was still noticeable, especially with 30 to 40 km wind gust, even with a Curt 4 point sway control hitch. After adding this product I noticed significantly lower sway and better towing.
by: Bryan 02/24/2024
They really changed the ride of my truck for the better. I pull a trailer five days a week and it fixed the squat. It also helped with wheel hop. Easy to install and well worth the investment.
by: DJonesy09/15/2023
I installed this with with my 4" Rough County lift kit. It was easy to install and made an overall improvement in the way my truck handles. I currently have the spring tension set to the thinnest shim and the rear end no longer sags to the bump stop when I tow my boat. I also noticed that the ride is a lot smoother without a trailer loaded on the hitch. No more axle wrap.
This kit was installed on my 2016 F150 XL 2WD
Be aware that you should not use any power tools to tighten the pre-load spring. The nut is made of a softer metal and mine rounded off while using a power drill to adjust it. I do not believe this is a self service item and the whole assembly may need to come off to be repaired.

I am extremely pleased with the RoadActive Suspension Custom Leaf Spring Enhancement Kit-HD. We have a 5000 lb (dryweight) fiberglass 5th wheel trailer (Escape 5.0 TA). The tow vehicle is a 2018 F-150 with the 53C towing package. The pin weight of the trailer is between 800 and 1000 pounds, depending foremost on fresh water, grey water, black water and propane tank loads. These custom leaf springs provide needed enhancement of the rear load-holding capacity. Fully loaded (truck and trailer), the tow vehicle is level front to back. No blinding of on-coming cars with my headlights.
Perhaps as important as the performance of the custom leaf springs, is the exceptional service that I received from etrailer. I screwed up the initial order by not specifying 4WD. I did not learn this until I was under the truck, installing the springs. etrailer was fantastic in handling my mistake. Before even receiving my returned product, they shipped me the correct springs and then they promptly refunded my money once they received the returned springs. Exceptional customer service.
Lastly, I will mention that etrailer prompted me to write this review one year after I received the product. I typically get asked to write product reviews by other companies days after receiving the product. Obviously, reviews written immediately after receiving a product are worthless for evaluating product durability.
So, etrailer stands out as a reputable company.

Easy install. Initial ride seems improved. Haven't pulled my trailers yet so too soon to tell how the RoadActive Suspension will improve the ride and handling, however, all reviews online that I read and watched, indicate they should help with the ride height, sway, and overall handling.
by: Daniel E06/08/2023
In addition to other products we purchased for towing our travel trailer this product has been exceptionally durable and helpful. I am beyond thrilled with how well this product has held up to the riggers of full time traveling. Very easy installation, pretty straightforward installation and design. I have referred other full time families to purchase this product for their rigs. Even if your vehicle (like ours) has the max tow package, have this added helps with the squat and weight distribution of whatever you are towing/hauling.

Initial install is super easy. This is waaaaaay better than airbags. No airlines, no worries about a compressor, no worries period. No difference in ride change, although the backend went up about an inch or a little better. Will send review in a year or so to let you know progress!

easy install, haven't tried weight on it yet,but seems to have smoothed ride on rear end, don't even notice when I go over small repair strips on road
by: Jamie 08/15/2020
Easy installation, although it should be noted the one bolt used for mounting is now a 3/8" Allen head bolt. Seemed to make the pick up ride "more confidently". Haven't used for towing yet as our trailer is on order. Will follow up if our review changes. Looking forward to an improved towing experience using this product coupled with our Hensley hitch.

This product exceeds our expectations! The towing experience is superb, and daily driving is greatly improved. No more rear end bunny hop!!! If you live your pick up you’ll love it even more with the RAS. And so will your passengers.

2019 Ford F-150
I thought it was too good to be true when I read the other reviews. It only took me an hour to install because I had to remove something else from a different suspension system. Once this was installed the truck had the same ride when empty as it did before I put it on. With our large 33 foot fifth wheel on our 2019 F150, it handled it perfectly. The back was still about an inch higher than the front once the suspension settled out in the full weight of the camper was on the hitch. When driving with the camper connected the suspension performs very well also. It’s not harsh and it acts like a Factory suspension would. I had a Timbren suspension before, and this is far better.

view full answer... - Does RoadActive Kit fit 2022 Ford F-150 with Active Assist and Blue CruseI checked with RoadActive and they do not have any fit exclusion for their # RAS3611-YHD that fits your 2022 Ford F-150 for models that have the active assist and blue cruse so this would work well for you without any issue.
view full answer... - Is the RoadActive Suspension Compatible With the Power Boost and Dynamic Ride On 2021 F-150?Yes, the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-YHD will not interfere with the power boost or dynamic ride systems on your 2021 Ford F-150.
view full answer... - Can RoadActive Suspension Kit Fit 2018 Ford F-150 with SumoSpringsThe Roadactive suspension kit part # RAS3611-YHD will technically fit your 2018 Ford F-150 and work just fine with your SumoSprings kit. I'd be a little worried that you are over the trucks capacity if you need two different suspension enhancement kits. Ideally just the RAS kit would give you enough support though.
view full answer... - What Suspension Enhancement Do You Recommend for My 2022 Ford F-150?For suspension enhancement on your 2022 Ford F-150, I recommend the RoadActive Suspension Custom Leaf Spring Enhancement Kit - Heavy Duty # RAS3611-YHD. The RoadActive leaf spring enhancement is a better choice than air bags because the leaf spring enhancements will provide more longevity out of your current leaf springs. They also involve an easy bolt-on installation that secures around the factory U-bolts on your factory springs. The heavy duty model comes with a 3,000 pound weight capacity....
view full answer... - Are There Air Bags That Fit a 2014 Ford F-150 with LiftI do have suspension enhancement options for a 2014 Ford F-150 but air bags won't work if the truck is lifted in the rear. Instead, I recommend the RoadActive Suspension Custom Leaf Spring Enhancement Kit part # RAS3611-YHD which like air bags are adjustable and will do a great job of providing extra support while towing or hauling. There will not be any fit issues due to the lift either unlike the air bags.
view full answer... - Which Heavy Duty RAS Enhancement Kit Fits A 2016 Ford F-150 4WD?For your 2016 Ford F-150 4WD the correct Heavy Duty RoadActive Suspension System is the # RAS3611-YHD. The # RAS3611-YHD has a 3000lb load rating to prevent sag when towing a trailer or carrying a heavy payload, and does an awesome job of preventing sway and body roll when your truck is loaded or unloaded. I included a video of the # RAS3611-YHD for you to take a look at.
view full answer... - Bolt Hole to Use on Lower Bracket of RAS System for 2020 Ford F-150I checked with RoadActive and when installing the # RAS3611-YHD the bolt hole to use on the lower bracket that fits under the spring is the second one from the very end.
view full answer... - What Does the Weight Rating for the RoadActive Suspension Help WithThe weight rating of the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-YHD for your 2022 Ford F-150 is probably geared more towards payload than towing a trailer because it gives extra support to the leaf spring suspension. Please note that the weight rating of this system (or any other suspension enhancement) won't actually increase the weight capacity of your pickup, rather it just offers support for that much weight. Attached is an installation video for you to...
view full answer... - RoadActive Suspension 2018 Ford F-150 Towing Highlander CamperThe HD version of the RAS system is definitely the way to go as it provides better support and stability when towing a trailer as heavy as yours compared to the non-HD version. Since you have a 4 wheel drive you'd want the part # RAS3611-YHD.

view full answer... - 2022 Ford F-150 Limited RoadActive Suspension Kit Fitment with On-Board ScalesThe RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-YHD is what you're looking for to fit your 2022 Ford F-150 Limited with the On-Board Scales. With that being said, if your trailer setup isn't sitting level while you're using a WDH then you might want to double check that your WDH is rated properly (you want your loaded trailer tongue weight to be in the middle of the tongue weight range of the system), and that you have it set up correctly as well. If either of these...
view full answer... - Will RoadActive Suspension for Ford F-150 Work with Weight Distribution WDHYes, you can use the RoadActive Suspension Custom Leaf Spring Enhancement Kit part # RAS3611-YHD with a weight distribution system on a Ford F-150. The spring bar tension won't be as high with the RAS as it woud be without but aside from that there won't be any negative affects. In regards to the integrated on-board trailer sway control, we don't typically hear of adverse affects with this and a weight distribution system.
view full answer... - Will RoadActive Suspension Fit 2018 Ford F-150 With 2" Leveler As long as you have the factory leaf springs the # RAS3611-YHD will fit your 2018 F-150 and function as intended. The 2" leveler won't impact the kit. It is possible that it will raise you up slightly, but that will depend on the condition of your leaf springs. It will not raise the rear end beyond the stock height. Basically, any additional lift would be from the kit returning the leaf springs to their original position.

Product is doing its job BUT it is hard to adjust the spring rate because of rust living above the rust belt. Knowing this, I would have maybe go with bags for the adjustment simplicity vs removing the back wheels every time an adjustment is needed
