RoadActive Suspension Custom Leaf Spring Enhancement Kit

Just installed,took about 3 hours. My 2015 tundra would drop 5" when I lowered the trailer, now it only drops 3" and sits level. Did a 15 minute test drive, I felt like the ride over bumps and dips was improved. The only complaint is the installation instructions were very poor.1745062

I really like the installation process and the results where good but I do wish I went with the heavier model1297322

I still wish I went with the heavier modal. But overall it’s a very good product. I just needed a heavier duty version.

2012 Toyota Tundra

Pretty easy install on my 2012 Toyota Tundra. I pull a 25’ airstream front BR travel trailer. It’s got at least a 1,000 # tongue weight. I was sagging in the rear, and getting a lot of porpoising when on concrete sectioned roads. The RAS eliminated the sag, and greatly reduced any porpoising. The truck seems way more planted with the airstream in tow. I’ve even moved it around a bit without the weight distribution bars in place. Truck is level now when towing. I know this doesn’t actually change the payload rating for the Tundra, but it sure changes how it pulls my trailer and hauls heavy loads. I also went to E rated tires.1171420

Very easy to install and make a big difference towing a trailer!717907

Overall, I'm super pleased with both the product and services from etrailer and the suspension enhancement seems to work well for my application. Small camping trailer, helped take away most of the sag.1400604

2013 Toyota Tundra

I really like the suspension add on. It keeps my truck level when towing our 9000 lb camper bumper pull. I get great stability on the road and it helps with handling the tongue weight on my 2013 Toyota Tundra 1/2 ton. It doesn't change the stiffen the suspension of my truck until I add weight. So, you don't notice it with normal driving. Installation went smoothly. The components were high quality and heavy duty. I recommend it.577747

Mounted on 2015 Tundra ,pull heavy car trailer and toy box these work great and are adjustable. Unlike airbags they won't leak and much easier install. They helped level truck when I'm loaded and resolved some front braking issues with the sensors on these new vehicled.319138

When I began the installation I set up the Tundra on my slopping driveway with chocks and attempted to jack it up with my small floor jack. Once I saw that I had to remove the spring eye plate I decided it was not very safe. I ended up going to my son-in-laws where he had a floor lift. After lifting the truck it was a very easy installation. I did watch U-tube about 6 or 8 times to make sure of the adjustments and as I said it went very well. Here are a couple of photos. 824255

We added these to my 2017 Tundra which we use to pull a gooseneck horse trailer. We camp on USFS lands and roads can be bumpy, rutted, etc. this stiffens up the suspension and we’ve never had any issues with bottoming out.873196

I bought this kit for my 2019 trd pro it’s an absolute must for the saggy leaf springs in the tundra especially the fox shocks but these give it a way better stance on the back with a 3” lift kit. you can tell this difference as soon as you drive the truck ABSOLUTELY FANTASTIC!!!!1143364

Shipped fast and the box had easy instructions. Definitely a DIY-capable project, and worth the purchase! -2018 Tundra 4x41295544

So easy to purchase w - Jessica/ Parts came across US just in time.
2nd X buying these, so will see HOW they fit in a couple of weeks.

I received this kit in a very timely manner always do from etrailer have some issues with the instructions that come from roadmaster not a trailer the bump stop spacer didn’t say that you need to use the original bolt from the bump stop so it slowed me down greatly on the install however I took it out on a quick run without a load I do feel that this has made the unloaded ride smoother tomorrow I’ll be taking the trailer out for a bit and we’ll see how it works there and I’ll update this rating.1387440

Admitedly, I haven't even rolled my '07 Silverado 2500HD classic out of the garage yet, but I'm already very pleased. I had to go to a neighbor for a 10mm hex key socket and was slowed down by my 7yo kid 'helping', but it was still only 90 minutes my jack stands were in use. Easiest thing to do!
My only small downsides so far:
* needed to find a 10mm hex key that I apparently don't own, not sure why they picked that fastener
* wish I put some loc-tite on; just to make me feel better
* distance to drop the axle so the suspension fully hangs was way further than I expected; barely had my jack stands tall enough to get the job done.

These aren't really bad on the product, just notes for future customers. We're towing the 5er about an hour an a half this coming week, hopefully it steadies up a lot!1377654

Overall, very happy with the product. GMC didn't have any way to improve the truck from squatting when I hooked up my trailer. This kit didn't stop the squatting but significantly reduced the bounce on bad dips in roads, bridge/road transitions and bad railroad crossings.1315767

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.1558048

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.1708587

Rarely adding an aftermarket "upgrade" to any of my vehicles am I 100% satisfied with the outcome. There is usually a trade off with something. However, this is one of those upgrades that has zero con's that I've discovered so far. I was struggling to keep the leaf springs on my modded out 3rd get Tacoma from "flattening" out because I always have at least 900 lbs of payload in my bed. Adding the RAS has prevented this from happening. I also thought that they would affect off road performance, since I've never seen them in an off road application before, they don't. People on the trail often ask "What the heck?" when they see them on my rig. I tell them that RAS is the easiest to install, most cost effective solution to manage sag without sacrificing ride quality. There is the famously noted "Taco lean" and it's most prominent after fueling up. RAS will help iron this out. I've had them on for about a year now and they haven't needed any adjustments. Kinda like (Ronco), "set and forget it". I don't know their duty cycle is but, I wouldn't hesitate buying them again!1635484

Love this product. I ordered a set for myself just before Christmas and I was so impressed that I ordered another set for my son’s truck. I was kind of worried that it would raise rear end too much but that wasn’t the case at all. If it raised it at all, it wasn’t noticeable. Definite improvement in handling bumps, cornering, and it eliminated any squat due to my pin weight of the 5th wheel. Highly recommend for an easy install (45 minutes) and overall ride improvement.1708532
