Features to know about
Stay Level and in Control Under Load: 1,000-lb Rear Suspension Support
When heavy gear or a trailer starts to push the rear end down, these helper springs pick up the slack. The SumoSprings Solo Custom Helper Springs add up to 1,000 lbs of rear support at 50-percent compression to help your factory suspension stay level. They absorb bumps and shocks so steering, braking, and headlight aim stay consistent even when the back end is carrying serious weight.
Smooth Out Every Mile: Progressive Load Control
These springs compress according to how much weight you’re hauling. With lighter loads, they engage softly for a smooth ride. Add more load and they can compress by as much as 80 percent to give firm support when you need it most. The progressive urethane design cushions bumps instead of jolting through them, keeping things comfortable whether the truck is empty or loaded.
Stay Steady in Crosswinds and Turns: Independent Spring Action
Each spring works on its own side of the vehicle, so an off-center load or sharp turn doesn’t throw you around. This independent action helps reduce body roll and sway through corners or in highway gusts. You feel more planted and in control even on uneven ground or winding roads.
Count on Tough, Maintenance-Free Construction
Built from durable microcellular urethane, these springs handle heat, cold, oil, salt, and UV exposure without breaking down. They compress vertically with minimal lateral expansion so they fit safely in tight spaces without rubbing nearby parts. There’s no air system to maintain—no tubing to run or pressure to check—just solid support that works every time you load up.
Install It Yourself Without Drilling
Adding suspension support doesn’t have to be complicated. These custom-fit springs bolt right in with a simple no-drill installation using basic tools. Two jounce-style springs are included so you can get your setup done and back on the road quickly with a leveled, confident ride.
