Front SumoSprings are a maintenance-free suspension enhancement built to create a better journey. Handmade from micro-cellular polyurethane, they are designed to stabilize weight transfer and limit body roll while decreasing vibration, stabilizing sway, and softening harsh rebounds. 

The SSF-106-40 has a 500 lb capacity when compressed at 50%. The Blue SumoSprings shouldn’t be compressed past 70% of their original height in order to keep full memory rebound.

Please Note: SuperSprings International products are specifically designed for vehicles equipped with factory suspension. We cannot guarantee their compatibility with aftermarket products or parts. For questions about fitment on your specific vehicle, please contact us.

When my wife and I head out in our 2023 Winnebago View we are looking for the best ride we can get. I don't like swaying back and forth in crosswinds or leaning in turns. And we try to miss every big bump in the road but that is not always possible. After 18 years and 2 Sprinter Class C motorhomes without doing any suspension upgrades, we decided to try front and back SumoSprings. I chose the blue front and black rear SumoSprings and Wow! they give the RV a more "planted" feel and a better ride without increased road noise or stiffness. I would absolutely buy them again. They have increase our confidence alot. My goal is to have a motorhome that drives more like an SUV. The SumoSprings along with new rear Fox shocks have given us a much improved ride. We now feel more relaxed when driving in cross winds and I can't describe how much better it feels to turn without leaning. Happy driving, hope you enjoy the road as much as we do.

After using Timbrens for 2 years what a difference! We had the Timbrens for a couple of years and the original set was way to hard of a ride. The Microwave almost fell out of the cabinet. They sent a second set of lighter springs. Still to rough of a ride. After removing these, we went a year without any helpers. This year I decided to try the Sumo Springs. What a difference in the ride and handling. I would recommend Sumo Springs to any motorhome owner. The ride is firm but not harsh. I wish we would have installed Sumo's in the first place.

Fast service. Received Sumo Springs a week earlier than I expected. Product was exactly as described. Installation was straightforward and relatively simple. The springs make a noticeable improvement in handling and stability of our van.
