Heavy trailers, campers, or bed loads can make the rear end sag and throw off your steering and braking. This RoadActive Suspension kit gives your leaf springs up to 2,000 lbs of support by turning them into a mechanically active suspension system. The variable-rated coil springs automatically adjust to your load, keeping your ride level and steady whether you’re towing or hauling. You get better traction, balanced weight on all tires, and smoother control when braking or accelerating.
When corners or crosswinds push your truck around, the RAS system steps in before sway or body roll even start. The built-in coil tension springs instantly absorb and dissipate load forces so the back end stays planted through turns and over rough roads. That means less rocking when a semi passes by and more confidence when driving curves or uneven highways with a heavy load behind you.
Axle wrap and wheel hop aren’t just annoying—they wear out suspension parts fast. Each RAS unit stabilizes the leaf springs to absorb force under load so they don’t twist or flatten out. By keeping the springs in their natural bowed shape, this setup eliminates axle wrap, prevents wheel hop, and stops bottoming out on rough pavement or steep inclines. Your shocks, shackles, and tires last longer because the system spreads stress evenly across the suspension.
This kit comes fully assembled for easy bolt-on installation—no drilling, cutting, or welding needed. Once adjusted during setup, it works automatically without valves, compressors, or air lines to monitor. The corrosion-resistant epoxy e-coated steel construction holds up with a salt spray rating of more than 800 hours, so you can count on durable performance season after season without extra maintenance or tuning before each trip.

Hello, everybody, Steve here with etrailer.com. Today we're looking at our RoadActive Suspension. It's a custom leaf spring enhancement kit. Now folks, these are a custom fit application, so make sure you're checking out our fit guide here at etrailer.com's home page. Enter things like year, make, and model. Make sure you're getting the right parts the first time.
Now folks, whether you're towing a heavy trailer or carrying a load in your truck bed, sagging can be both dangerous and frustrating. But with the RoadActive Suspension kit, this is gonna transform your vehicle's rear leaf springs into what's considered a mechanically-driven active system. So no airbags to mess with, no leaks, anything like that to ever have to worry about. These will keep your ride level with a 2,000-pound capacity. And they're gonna instantly support the extra weight, thus preventing sag and maintaining your vehicle's stability whether you're towing a camper or just filling up the back of the truck with gear.
Now, these are going to instantly respond, and they're going to immediately react with the weight without affecting your ride quality. Now, zooming in, you can see the heavy-duty spring construction and all the parts have been powder coated. So you don't have to worry about rust, corrosion, those kinda things. And per the instructions, you'll mount these in unison with your factory suspension system. And they will tell you how and where each piece mounts up to be safe and effective.
Now, they basically mount to your existing attachment points on the vehicle on the rear leaf spring suspension to help stable out the hauling, towing, whatnot. Well, folks, that's gonna wrap it up for our quick look together. Again, my name is Steven. Thanks so much for your time. Thanks for watching.
As always, we do welcome feedback and photos of these installed. Let us know how they perform before and after you've installed these. Have a good one.

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.

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?

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.

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.

OMG!! I have done extensive traveling with my trailer over the last year and the RAS system has made a huge difference in sway, road buffeting and squat. I can’t imagine not having this on any vehicle that tows!
