Heavy trailers and bed loads can make the rear end sag, throwing off your steering and headlight aim. The RoadActive Suspension Custom Leaf Spring Enhancement Kit adds up to 2,000 lbs of support by turning stock leaf springs into a mechanically active system. Variable-rated coil tension springs automatically adjust to your load so your truck stays level when towing or hauling. When unloaded, they disengage to keep the factory ride smooth without stiffness or bounce.
When weight pushes your leaf springs flat, traction and control drop fast. Each RAS unit uses a powerful variable-rated coil tension spring that immediately activates under load to absorb and support weight before sag sets in. This prevents axle wrap and wheel hop that cause jarring movement and tire slip. By keeping the springs in their proper bowed shape, the system helps extend the life of your shocks, shackles, and tires while giving you steady traction for braking and acceleration.
Towing a camper or hauling a tall load can make turns feel top-heavy and unpredictable. The RAS system reinforces the factory leaf springs to keep the vehicle planted through corners and windy conditions. It stabilizes side-to-side motion so sway and body roll are reduced whether you’re turning into a steep curve or getting passed by a semi on the highway.
Adding real suspension support doesn’t have to be complicated. This all-in-one kit comes fully assembled with corrosion-resistant epoxy e-coated steel construction and brackets rated for more than 800 hours of salt spray. It bolts under the leaf spring and around the factory U-bolts with no drilling, cutting, or welding required. Once installed, no adjustments or maintenance are needed—just dependable load leveling every time you hitch up or haul heavy gear.

Sorry to hear that. Is your 2024 Silverado 3500 a dually by chance? We do have options for trucks with the top overload springs, but the one you ordered is not compatible with that option. The ones that will fit do specifically say they will fit with the top overload spring, but I will need to know if you have a dually or not.

I have my RAS system for two years now and it performs as well the day I installed it.

I have had this installed on my van for a few years now and I was just reminded of them again when I got new tires put on. I was explaining them to the mechanic. He had never seen them before. I was giving a raving review and realized that I should be doing it here. I live at 6000ft on a mountain road and am constantly driving switchbacks. Before I had these installed I crawled down the mountain. It was literally scary. After they have been installed it feels sturdy and I can take turns easily. I can even avoid crazy deer jumping out in front of me without losing control of my huge van. There is NO way I could do that on a narrow winding road at an angle before. I have countless instances where I have blessed these simple additions for saving my van and ultimately the life of my children. Thank you so much for making these and marketing them. They should be standard in these larger vehicles.
