The Sumo Spring bump stop replaces the factory bump. It contacts the control arm at ride height to increase the front suspension spring rate, while still compressing to the height of the factory bump stop. Suspension travel is not reduced. The additional spring rate reduces sway, improves control in high winds and comfort while the suspension cycles. We install these bumps stops on most our our customer's vans. You will feel the difference in ride quality. Recommended for all vans, even those that are unloaded.
All SumoSprings are manufactured from proprietary closed microcellular urethane with materials density, tensile strength, elongation, tear resistance, rebound, and compression characteristics designed specifically to suit drivers’ applications. Made in USA.
