When you hitch up a trailer or load the bed with heavy gear, the rear end can sag and make driving feel off. These SuperCoils replacement springs add 2,475 lbs of rear axle support to keep your truck level and balanced under load. By swapping out your factory coils with these heavy-duty springs, you maintain stock ride height while getting the strength to handle serious hauling without squat or bounce.
A sagging rear end shifts weight off the front tires, hurting traction and steering control. SuperCoils help even out that weight so the tires stay planted on the road. With better contact between all four corners, braking feels steadier and steering stays responsive—even on long highway drives or steep grades with a trailer behind you.
Heavy loads can wear down factory suspension parts fast. These beefy coils take on that strain, reducing wear on your stock components and tires. They’re a direct replacement for your OEM coils, giving your suspension a stronger foundation without changing the standard ride height or needing ongoing maintenance.
Once installed, SuperCoils just work. There’s no air pressure to monitor or hardware to adjust—just a solid coil spring setup that holds up to daily use and towing alike. They’re built to deliver long-term stability and control for anyone who regularly hauls heavy cargo or pulls a trailer.

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.
