Bump Stop

Bilstein M 9100 (Bump Stop) is designed to provide a significant increase in compression control over the last few inches of suspension travel on custom off-road applications. M 9100 (Bump Stop) is available in 3 different stroke lengths ranging from 2-4 inch travel that can accommodate a wide range of custom mount configurations. M 9100 (Bump Stop) has a replaceable strike pad for easy maintenance. This bump stop utilizes a nitrogen fill valve which can be used to fully adjust the compression force. When properly applied, M 9100 (Bump Stop) will effectively decelerate the suspension and prevent harsh bottoming on custom off-road applications.
