An energy absorption device for providing a softer stop arrangement between a pair of components. A bumper is provided with a cylindrical insert mounted therein. Upon application of force between the components, the compressible bumper collapses around the insert and outward. The insert prevents the bumper from expansion inward of the bumper to limit the amount the bumper compresses and further is made of a flexible material to absorb energy. The combination of the bumper and the insert provides a definite stop to the bumper assembly. The device is usable between any two components to prevent collisions between the components up to a certain force between them and is also usable between a strut assembly and a vehicle suspension to prevent the strut assembly from bottoming out.
