SSF-109-40 front sumosprings for ford excursion
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.
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 SSF-109-40 has a 1,000 lb capacity when compressed at 50%. The Blue SumoSprings shouldn’t be compressed past 70% of their original height in order to keep full memory rebound.
