Heavy trailers or full bed loads can make the rear of your rig sag and the front lift, throwing off steering and braking. These SuperCoils replace the factory rear coils with heavy-duty springs rated at 2,058 lbs per coil to hold the back end up where it belongs. With the weight more evenly distributed between axles, your tires keep solid contact with the road for smoother handling, steadier braking, and properly aimed headlights when towing or hauling.
Once installed, these coils go to work without air lines, valves, or adjustments. The maintenance-free design means no compressors to check or leaks to chase—just consistent support every time you load up. They help eliminate squat under load so you can tow or haul knowing the suspension will handle the extra weight without constant tuning.
Replacing tired factory springs with these beefy SuperCoils helps prevent bottoming out and spreads load forces more evenly through the chassis. That reduces strain on shocks, bushings, and tires while keeping your suspension geometry in line. Less sag means less wear on key components and a more controlled feel over bumps and dips.
These coils maintain stock ride height while adding serious support to the rear suspension. You get a setup that strengthens your truck’s stance for towing or hauling without changing how it sits when empty. The result is a level ride that feels confident whether you’re on the highway with a trailer or running light around town.

Our 1500 Ram with a hydraulic lift gate is still holding up to daily abuse. I was told that I needed to step up to 2500, but did not have the means as a company at the time. Our crew cab Ram 1500 doesnt bend the knew to any load.
