  • SumoSprings Part Number SSF-503-40
Total Price: $674.98

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 SSR-504-60 has a 4,000 lb capacity when compressed at 50%. The White SumoSprings shouldn’t be compressed past 45% of their original height in order to keep full memory rebound.
