The SSF-106-47 

has a 1,000 lb capacity when compressed at 50%.
The Black SumoSprings shouldn’t be compressed past 65% of their original height in order to keep full memory rebound.

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.
