THE AIRBAG ALTERNATIVE.
No lines. No leaks. No maintenance.
That means no maintenance, plus a lifetime warranty too.
No rubber was used in this creation of a better journey.
SumoSprings are not made from rubber. They are a progressive spring with a very soft initial engagement. That means that as more weight added, the harder they get and more they push back, providing support and control when you need it without affecting the factory ride when unloaded.
These are a suspension enhancement built to create a better journey. Manufactured from our micro-cellular polyurethane, they are designed to reduce rear-end sag, decrease vibration, stabilize sway, and soften harsh rebounds.
