SSR-107-54 SumoSprings Rear Solo Kit for Ford E350/E450
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.
The Solo Kit is a one-piece unit attached on one side used as a replacement/upgrade to factory bump stops.
The SSR-107-54 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.
