Features to know about
Stay Level and Confident Under Load: 2,800-lb Rear Suspension Support
Heavy trailers and bed loads can make the rear end squat, throwing off steering and braking. These SumoSprings Solo Custom Helper Springs add up to 2,800 lbs of support at 50-percent compression to keep your ride level and steady. They work alongside your factory suspension to bear extra weight, reduce sag, and keep your truck stable under load so you stay in control when towing or hauling.
Smooth Out the Ride: Progressive Microcellular Urethane Springs
Rough roads and uneven cargo can make a heavy setup bounce or sway. The microcellular urethane springs compress progressively—soft at first for light loads, then firming up as the weight increases. That means you get a smooth ride unloaded and confident support when the bed is full or the trailer is hooked up. The closed-cell material also dampens vibration to make long hauls feel more controlled and less harsh.
Reduce Body Roll and Uneven Handling: Independent Spring Action
When turns or side loads push one side of your truck harder than the other, each SumoSpring compresses on its own to balance things out. This independent action helps reduce body roll, sway, and porpoising so your truck feels planted in curves or crosswinds. It also compensates for off-center loads, keeping steering more predictable even when cargo isn’t evenly distributed.
Rely on Simple Strength: Maintenance-Free, No-Drill Design
There’s no air pressure to monitor or lines to run—just solid suspension support that’s always ready. The durable urethane construction resists oil, salt, and UV damage while performing in temperatures from -25°F to 200°F. Installation is simple with no drilling required; the springs mount in place of your factory jounce bumpers for a clean fit that’s built to last.
