ssr-290-54 rear sumosprings chevrolet/workhorse p30/p32
Rear SumoSprings are a maintenance-free suspension enhancement built to create a better journey. Handmade from micro-cellular polyurethane, they are designed to reduce rear-end sag and increase load carrying ability while decreasing vibration, stabilizing sway, and softening harsh rebounds.
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.
The SSR-290-54 has a 2,800 lb capacity when compressed at 50%. The Yellow SumoSprings shouldn’t be compressed past 55% of their original height in order to keep full memory rebound.
