Promaster SumoSprings Combination Package

Get both front and rear SumoSprings together for your Promaster van in this Combination Package. These are the popular and well used SumoSpring helper springs for Promaster vans, cab chassis, 1500, 2500 and 3500.  Great for RV's and contractor vans.

Adjustable length on the rears allow flexibility for fine tuning. Each side will have two 1" spacers which will make the product 6.5 inches or 7.5 inches in length depending on spacers used. This allows you to have the SumoSprings engage more by using both spacers or less by using one.

The fronts are a quick and easy way to enhance the front suspension. Installs between the coils on the front springs.  

SumoSprings are a micro cellular urethane product designed to help reduce 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. No modifications or drilling are needed.
