Transit passenger wagon rear SumoSprings or helper springs for the 150,  250 and 350 - available for light duty, medium duty and heavy duty applications. 

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 Transit SumoSprings mount using the factory bump stop brackets. No modifications or drilling are needed.
