This is the FIRST hydraulic bump stop on the market for a Dodge Ram. Carli's front bump stop kit does not reduce wheel travel. Only the final 2.5" of travel will utilize the bump stops. The bump stops 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 bump stop is dissipated as heat thus preventing the suspension from bottoming out , leaving everything still in place on your dash. Also, the rebound of the bump stop is designed to extend at a slower rate which will keep from forcing the axle back up, 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. The hydro-pneumatic bump stops offer "position sensitive" high-speed compression dampening. When you take a big hit and stroke the shock piston through the travel and the bumpstop engages, it dramatically increases the compression dampening in the last 2.5 inches of travel, offering substantial bottom out protection. Low speed dampening is unaffected, and here's why; you can compress the bump stop slowly to full up travel. The bump stops are designed with low flow pistons and are valved (tuned) to absorb high shaft speed impacts, yet still allowing the axle to articulate slowly to full bump without resting on a fully extended bump stop.
