Extended Sumo Spring bump stops for Mercedes Sprinter 906/907

Extended rear suspension stop sumo spring for Mercedes Sprinter W906 and W907

The Sumo Spring replaces the factory stop. It contacts the rear axle earlier to increase rear suspension spring stiffness, while compressing to the same height as the original suspension stop. Suspension travel is not reduced. The extra spring stiffness reduces sway, improves control in high winds and enhances comfort during suspension cycles. We install these bumpers on most of our customers' vans. You'll feel the difference in ride quality. Recommended for all vans, especially those carrying heavy loads most of the time or towing trailers. The extra spring will reduce rear suspension sag. They are perfect with our Koni rear shock absorbers for a complete change in driving dynamics.

All SumoSprings are made from exclusive closed microcellular urethane with density, tensile strength, elongation, tear strength, rebound and compression characteristics designed specifically for driver applications. Made in the USA.
