A heavy front load can cause your suspension to sag and throw off steering and braking. These SumoSprings Solo Custom Helper Springs add up to 1,500 lbs of front-end support at 50-percent compression to keep your ride level and controlled. The microcellular urethane design cushions bumps and shock while helping your factory suspension handle extra weight so your front tires stay planted and your steering feels steady.
No two loads ride the same, and these springs automatically adjust to match. The progressive design compresses easily for lighter loads to keep the ride smooth and comfortable, then stiffens as weight increases—up to 80-percent compression—for added support when things get heavy. You get less bounce, sway, and harshness whether you’re rolling easy or fully loaded.
When a crosswind hits or a turn tries to push you around, each spring works on its own to keep that side of the vehicle stable. This independent action helps cut down on body roll through corners and keeps off-center loads from throwing the vehicle off balance. The result is a more planted feel on the highway or when maneuvering into tight spots.
Made from microcellular urethane that resists abrasion, oil, road salt, and UV rays, these springs are built for long-term use in all seasons. They perform reliably in temperatures from -25°F to 200°F and compress vertically with minimal side expansion so they fit safely even in tight suspension areas. There’s no tubing or air pressure to maintain—just a maintenance-free setup that quietly does its job every mile.
Adding front suspension support shouldn’t require special tools or shop time. The custom-fit jounce-style springs mount easily with no drilling needed, using straightforward hardware that fits right into place. In just a short time, you’ll have your front suspension leveled out and ready for smoother handling under any load.

It was a great investment. It truly helped with the front end bouncing. I look forward to adding a set to the rear.

The Sumo Springs on my W-24 chassis have given me a much softer ride during the last 10,000 miles. When you are sitting right over the front axle in a motorhome, you feel every bump in the road. Sumo Springs help smooth out those bumps.

That is awesome to hear! It must be such a relief to not have to put so much energy into controlling the wheel while driving now.
