Promaster City SumoSprings Rear Helper Springs
Promaster City rear SumoSprings or helper springs for the little vans. Great for contractor vans or any loaded Promaster City van. Sold in pairs.
SumoSprings are a micro cellular urethane product designed to help reduce rear-end sag and stabilize sway.
They are a progressive spring with a very soft initial engagement. That means that as more weight is 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.
Easy installation with no leaks and no maintenance. The Promaster City SumoSprings mount using the factory bump stop brackets. No modifications or drilling are needed.
