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.
The Promaster City SumoSprings can help reduce side to side movement, sway, and rocking. No modifications or drilling are needed. They mount using your factory bump stop brackets.
SumoSprings are a micro cellular urethane product designed to enhance load carrying ability and stabilize sway. They can also help decrease and cushion hard bottoming of the factory springs on vehicles that are at or near their weight capacity. These springs are a progressive system that increase load holding capacity as the product compresses. Soft riding with easy installation and no maintenance. They work much like an air bag system, but with thousands of tiny air bubbles that never leak out. Helps with both jounce and rebound as they absorb energy on compression. Do not exceed GVWR for your vehicle.
