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-170-40-2 has a 3,000 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.

Installed Sumo Springs on the front of my motor home. The passenger side was relatively easy. The drivers side bump stop nut is not welded in the frame. If you are not very mechanical inclined, pay a professional to do the installation. The Sumo Springs make a big difference. I recommend them. Will be ordering the back springs as well.

We want to thank you for the great sumosprings products. We installed them on our 08 Bounder and the changes were night and day. Better ride, handling, less sway etc etc. It rides like a different coach and we are extremely grateful. I would recommend sumosprings to everyone. And the installation was not bad at all. Did it myself in about an hour and a half. Thanks Sumosprings.
