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 put these on my 2018 F150 and towed a fully loaded 17' foot cargo trailer from from Washington to Florida through bad weather and even performing some high speed emergency avoidance. I feel that the safety of that trip relied heavily on the positive effects of Roadmaster on my suspension!

I like the way that I can track the order status from the person preparing my order to the time it is delivered. It feels like it is very personalized. Thanks for getting my order delivered earlier than I expected.

After going back and forth with your install techs before purchasing they said what product to buy. I order it and doesn't fit my truck due to flipped rear axle I gave them pics so product was returned
by: Carl08/23/2020
I installed them on a 2015 F150 2WD. Pulling a trailer with about 750 ponds tongue weight. Before the RAS my truck dropped 3 1/2 inches in the back and raised 3/4" in the front. With the RAS the back still dropped 3 1/4" and the front raised 3/8". They say it doesn't affect the ride without a trailer hooked up. I would strongly disagree with that statement. The ride and handling are affected and not in a good way. Much stiffer. With the trailer hooked up the truck does seem to be more stable, although I have not pulled it a long distance. I am mainly disappointed that it basically did nothing to help the rear end sag. I tried both wafers for adjustment. Not much difference.

Not good. I removed them after a long trip. Going back to airbags that way when not towing I can let the air out. With RAS and trailer hooked up the truck rode like a dump truck. I would not recommend and would give it a one star rating. I feel like I wasted my money.
by: Sandra08/31/2021
I am a first time truck and trailer owner. Talked to friends and did my research and decided on airbags. Purchased Airlift bags. They gave me the worst ride around town, my F150 drove like a bouncing tank and didn't improve the towing ride at all, made it a little worse. So I decided to return those and went with Roadmater AS. My truck around town felt better than factory. My truck takes corners better than any of my friends truck. Towing is smooth and sway in no more.

2018 Ford F-150
2018 F150 4x4 owners pay attention to this review. I received the order today and unfortunately it was the wrong kit for my vehicle. Even though etrailer confirmed that a RAS3611-B is correct for my truck, it is actually for a F150 4x2.
I contacted etrailer and costumer service rep was great and verified that initially the same part number came up for my vehicle, causing the confusion.
My mistake, etrailer mistake.
The correct kit for a 2018 Ford F150 4x4 is RAS3611-Y.
etrailer is splitting the cost of return shipping and my correct kit has been ordered.
etrailer has great costumer service.

Found the installation to very easily! I was able to do it with the tires on the truck and less than 30 minutes to install both. Product seems to work really well but only have loaded it a few times. etrailer has some of the best customer service I have seen in awhile! I will definitely use them for my future needs!

Really helps with towing and stability when hauling large loads. I never go more than my vehicle’s specs, but when I’m close to the max these help a ton.

Fantastic! While my towing is within spec, these help so much with stability. After owning them for a year I know I made the right choice.

I received my order a day earlier than estimated. That was nice. But, when I started the installation the next day, I immediately encountered a problem when installing the enclosed bracket for the emergency brake cable. The instructions state the O.E. bolt is 10mm. On my 2017 F-150 the bolt is 13mm and does not fit in the recessed hole on the supplied bracket. I'll unfortunately be making a trip to the local hardware store to find a bolt that will work in order to complete the installation.

Thanks for the info, I have spoken with my contacts at Roadmaster Active Suspension and they have not heard about this issue, but their development team is looking into it to see if they need to update the bolts included.
by: Joe B05/08/2020
Really great product. Install on 2017 f150. The truck bounced because it was lite from aluminum frame. It's suspension was weak. My trailer with my small tractor seem to over load rear suspension. Load was for below truck tow rating. Caused problems loading and unloading tractor. Roadmaster really changed the suspension for the better. Truck is very stable and much smoother with and without trailer. A GREAT PRODUCT!!!

After debating whether to go with these or airbags for a year I’m very happy with my decision to purchase these for my 2015 F150. Installation was simple, the difference in ride and towing is great, and there’s no maintenance. With 1,000lbs of trailer tongue weight and improved stability, I’m a happy camper!

- Do You Recommend the Standard or Heavy Duty Roadmaster Leaf Springs for My 2022 Ford F-150?When considering a RoadMaster leaf spring enhancement on your 2022 Ford F-150 (2-wheel drive), I recommend going with the heavy duty Roadmaster Active Suspension Custom Leaf Spring Enhancement Kit # RAS94FR over the standard Roadmaster Active Suspension Custom Leaf Spring Enhancement Kit # RAS3611-B.

Hello David, I am sorry this product did not fit your truck. I spoke with our Roadmaster Techs and they told me this kit is not a fit for your truck since your truck suspension is not factory spec. This kit is only confirmed to fit the fit-guided vehicles with factory suspensions.
