Features to know about

Stay Level and Confident: 2,000-lb Rear Suspension Support

When heavy loads cause your rear end to sag, steering and braking can feel off. This RoadActive Suspension Custom Leaf Spring Enhancement Kit adds up to 2,000 lbs of support to help keep your ride level when towing or hauling. The system converts your factory leaf springs into a mechanically active suspension that strengthens under load and eases off when empty. You get balanced traction, better handling, and steady headlight aim without bottoming out or a stiff unloaded ride.

Vehicle equipped with RoadActive Suspension kit maintaining a level stance while loaded, showing improved ride leveling and traction.

Cut Down on Sway and Body Roll: Mechanically Active Coil Tension Springs

Sway and body roll make towing feel unstable, especially in corners or crosswinds. This system uses variable-rated coil tension springs that automatically adjust to your load to stabilize the vehicle before sway starts. The heavier the weight, the more assistance they provide. The result is a planted, confident feel through curves and over uneven roads with less bounce or lean when passing trucks or windy conditions hit.

Stop Axle Wrap and Wheel Hop: Strengthened Leaf Spring Support

When torque twists your leaf springs under load, axle wrap and wheel hop can take over. The RAS kit absorbs that force before it reaches the axle, keeping your leaf springs in their proper shape so traction stays consistent. That means smoother acceleration, steadier braking, and reduced strain on shocks, shackles, and tires for longer component life.

RoadActive Suspension system installed on rear axle showing elimination of axle wrap and wheel hop for improved stability.

Install It Once and Forget It: Fully Assembled, Maintenance-Free Design

This kit bolts directly onto your factory leaf springs with no cutting or welding required. Each unit comes fully assembled with brackets, hardware, and a drill bit for setup. Once installed, no adjustments or maintenance are needed—the system automatically engages under load and disengages when empty for a smooth daily ride. Durable epoxy e-coated steel construction with corrosion-resistant brackets rated for more than 800 hours of salt spray keeps it working season after season.

2014 Nissan Leaf

I was looking for something to prevent my 2014 Raptor from squatting from pulling my 24' boat. New leaf springs were $1500+. Airbags would have worked, however I didn't want to lose suspension travel when unloaded. Then I came across the Roadmaster Active suspension system. I watched lots of videos, and was convinced this is what I needed. Installation instructions were written well, and followed step by step. The only thing I did that wasn't noted in the instructions was file the burs off of the u-bolt bracket, then repainted each bracket to prevent rust. I haven't had a chance to run with the boat attached yet, but unloaded, the truck seems the same. It is slightly firmer ride, but not stiff. (I set them at 40%). Cornering is much better and less body roll. Bumps and dips have less bounce, and more control. I wonder why this isn't a standard option on all trucks...

2026 GMC Sierra 1500

Just perfect to level the rear of my GMC 1500 Denali with the 29' Airstream (900 lb tongue wt). Preload is set at 1mm. I tried 2mm and it was overkill for this application. I was pleased with how easy the install was. I had to use a two jack hack to get the rear tires off since my 19" lift floor jack didn't quite have enough reach. You lower the differential after the tires are off so the rear axle is hanging free for the install. See photos

Nicely done, Sam! Thanks for the photos, we always appreciate those!

The install takes about 30 minutes with a floor jack and jack stands. You do not need to remove the center tension bolt just lengthen it out. Lay the assemble over the spring and install one bolt on the ender side. Snug up the spring to desired % of tension and you are good. I did not remove the tires there is no need as you can get to everything. If you can not secure the frame in the upright position with stands I would remove the tires for safety.
The good is the brackets fit nice on the leaf springs and at 25% (the white washer) it lifted the truck 1.5 inches.
The bad is the enhancement bracket that passes by the leaf spring on the drivers side rubs against the brake line hard. I am pretty sure this is an issue with the Tacoma pickups if you look on line. Customer service at etrailer gave me the I don't know you need to contact the manufacturer. Own up and do not pass the buck is my response to that answer. My fix was to loosen the hold down bracket on the brake line under the leaf spring assembly and add 2 washers behind it to move it out away from the plate 1/8 inch. While doing this and before retightening this bracket bolt I also loosened the line bracket bolt fixed to the axle farther to the right and rotated it a little while bending the brake line ever so slightly to create a 1/4 gap between the break line and the enhancement kit bracket when it was tightened back on.
My two cents.

Well It has not failed me yet. Being basically a spring under load all the time I am assuming the spring will stretch some over time and I will have to adjust tension accordingly. The pickup sits nicely on the thinner washer setting so I am leaving it there and hopefully that will help the system last longer.

I don’t think they are really made for the old PU. 1997 k1500 8 ft bed with a 750 lbs camper tong weight I think I had to put to much pressure on the Kurt stabilizer chains to get level. It looked like the newer truck reviews on YouTube were great thanks Dingler.

I purchased the RAS system 6 months ago to help with rear end sag & control while towing our 22 ft 4200lb camping trailer. It improved sag & helped handling even when not towing! I don't get the bounce when driving on bumpy uneven roads the wheels stay planted on the road. I recently purchased a 8000lb camping trailer & my 24 1500 Silverado handles it very well, I will adjust the RAS to the next step up for the extra weight when time permits.
The install took just over an hour with help from a friend & a car lift which is good since I'm 70 years old.
Great product!

Looks great, Les :) I hear lots of good this about this option for suspension enhancement and how you said, even without towing it can improve the ride quality. Glad to know that you are happy with them, too! do you have any upcoming camping trips planned?

Ford F-150

Installation was very simple. Watched many installation videos and had no issues with installation. Wanted to gain an extra 1 inch in height in the rear on my F-150 while towing my travel trailer and actually gained 1.5 inches in the rear and only lowered the front by 1/4 inch. very satisfied with it so far.

by: Vince 07/29/2025

I’ve bought a lot of products from etrailer and as always everyone I dealt with is professional and knowledgeable of the numerous products they sale. I used every resource they offer to help me decide what type of suspension upgrade I was going to use to improve the haul and tow ability of my 2017 diesel chevy Colorado 4x4 crew cab short bed. I chose the RAS system from Roadmaster. I also called them and ask some very detailed questions about using my OEM shackle instead of replacing with the plates in the kit and was told that was fine and that others had also. I got professional and knowledgeable info that helped make my decision. The product is exactly as promoted and every review out there on the internet about how good or unchanged the unloaded ride is after installing are true. My truck rides better now and it was already quieter and almost as smooth as my wife’s Cadillac. If your looking to improve the drive, tow and haul ability of your leaf spring vehicle, and I say vehicle instead of truck because I don’t know if they have them for other leaf spring vehicles, you are not going to find a better easier to install product that does that for your loaded or unloaded vehicle, IMHO. I will update in a year after next spring mulch haul. I don’t expect zero squat but hope to reduce and improve loaded steering performance. Took longer to jack up truck and remove tires than install kit.

Ford F-150

2023 F150. Install was fairly easy. Set at 25%. Ride unloaded a bit stiffer, but handling much better. Lifted rear of truck about an inch. Towing 7500 lb camper down NYS thruway which is crowded with much unforgiving bumps and pot holes the ride was more manageable. The 25+ mph cross winds did make for quite a bit of sway still, not as bad as before adding the RAS. Still felt passing trucks trying to suck me in, not as bad as before.
I plan on cranking the RAS to 40% on next camping trip and hopefully give the RAS 5 stars.

Easy install when I rotated tires. Forgot to measure height difference, but it did raise a bit. I like the adjustability and not having to remove springs and shackles to add a leaf. Will be towing the camper with improved support.

Great product, helps with sway and when the truck has additional weight it progressively compensates. I would add this to any vehicle with leaf springs.

by: Sergio 08/12/2020

2011 Nissan Titan

The bed of the truck measured 37.5" with a tool box weighing 200 lbs. The truck felt weighed down with passengers weighing 600lbs. Total weight 800lbs with a tank full of gas. After the install the truck rides smoother and certainly " like new". The stopping distance and acceleration distance have shortened drastically. I'm planning on loading up the bed and the Roadmaster Active Suspension RAS4611. My wife even drive it and she could feel the difference. "It drives like a muscle car." Buy it. Install time at a reputable mechanic shop was a 30 min. Install. I received them today at 1 pm and got it installed at 3:00 pm and finished the install at 3:30pm. It's an investment worth the price over traditional air bag system. Mechanic installed this on 2011 Nissan Titan SV.

What can I say. After a year of constantly driving through Texas roads and highways. I have moved twice and loaded the bed of my truck plus U-Haul 6x12 trailer and thy truck has not felt the load of it. The Active Road Suspension Leaf Spring is constantly sort of speak sensing if theres load so it can actively push it upwards. I have even driven up to the crazy roads of Pennsylvania and my pick drives smoother than when I got it from the dealer. Im telling you these things work. As any cautious driver upkeeping his own vehicle, I have periodically checked the bolts and location of the resistance in between the spring and it has not deflected or moved from its original installation. I believe every pick up must have these. It beats constantly putting air on the air bags especially in inclement weather like up here in Pennsylvania with the snow. I couldnt be more satisfied with this purchase. Thank you etrailer for offering this superb product.

Its been working very well i loaded a couple of times and its awesome

by: Rick Maybury 03/26/2021

I have a 2020 Silverado 1500 6 cyl Duramax with the Diesel Off Road package (3.73 diff). Travel trailer loaded is probably about 6,000 lb. I took several measurements during and after the spring kit installation. All measurements increased about an inch including the stock suspension with trailer and equalizer bars and with the spring kit installed at 1 mm spacing. A one inch improvement overall. I took the truck on a short drive and didn't notice any difference in ride (wasn't stiffer) which is what I wanted. Good to know that I can adjust the springs to the 2 mm spacing if I want to increase the suspension assist. Going camping next week and looking forward to see how it improves handling and porpoising.

After a year I am still pleased with this product. I had been adjusting the spring tension higher when towing and then back down after a trailering trip, but now just leave it adjusted to the trailer towing tension as the unloaded ride doesnt seem to suffer when the springs are tighter.

Easy install 2011 Tacoma crewcab long bed. Helped with sag when towing microlite travel trailer. Keeps the rear end raised in the rear a little when unloaded, but I like that look. Only complaint and its nothing big when truck is unhooked and empty when i get out I can hear alittle noise from RAS. Sort of like a bedspring coil.

2017 chevrolet Silverado

I haven't hooked up my camper yet but set the springs up with the white wafer and it raised my truck 1 1/2 inches which is the amount it dropped after I put on a fiberglass topper. The ride is just a bit stiffer but a lot less body roll I noticed. Not impressed with the 25 Silverado suspension compared to my previous 2017 truck. If the squat is still there after I hook up the camper, there is plenty of adjustment left.

2001 Nissan Leaf

i installed these on my 2001 ford f-250 4x4 and this is a huge upgrade whether your towing or empty.truck rides and handles better than it ever has. easy straight forward installation. you will need a t-55 for the front bolt and a 12mm ratchet wrench for the adjustable bolt that tightens the spring and a couple of 22mm and a 19mm wrench or crescent wrenches for the jam nuts. i took the weight off of the leaf springs for easy adjustment of the coil spring and used the thinner of the two disc that came with the kit and it raised the rear of the truck up exactly 1 inch empty without a trailer connected. if you use the thicker disc it will raise it more.

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.

Can I use RoadActive Suspension with Timbren SES on 2010 Ford F-150 Raptor?
Using these two products together is going to be a little bit of overkill, but I spoke with RoadActive Suspension and they mentioned that as long as your current bump stop (which would be replaced by a Timbren system) sits inboard towards the center of the vehicle from the U Bolts and Leaf Springs by about 1/4"-1/2", there shouldn't be any interference with the two components.
