This is the FIRST hydraulic bump stop on the market for a Dodge Ram. Carli’s rear bump stop kit does not reduce wheel travel. Only the final 2.5 of travel will utilize the bump stops. The bumpstops act as a secondary suspension system. This system was designed to protect your truck from those unforeseen hits when pushing the limits of the suspension. All of the energy used to compress the bumpstop is dissipated as heat thus preventing the suspension from bottoming out , leaving everything still in place on your dash. Also, the rebound of the bumpstop is designed to extend at a slower rate which will keep from forcing the axle back down, which would cause the suspension to bounce back. By slowing down the last couple of inches of compression travel, you reduce the amount of stored energy that needs to be controlled on the rebound side. This will help maintain control of the vehicle when off-roading at speed.
