FOX Bump Stops were created to provide additional bottom out control to maximize the vehicles entire suspension travel. Developed in conjunction with top off-road racing teams to achieve ultimate performance within a compact and light package. The FOX bump stop can easily be setup for any conditions by removing the aluminum Schrader cap and adjusting the internal nitrogen gas pressure. The long lasting and replaceable Delrin pad insures quiet operation.

These 4.0” Air Bumps are used similar to an Air Bag System. 200 psi in the Air Bump is roughly equivalent to supporting 3000 pounds in the bed, and the air bumps can be filled up to 600 psi.

Available with different length pads - +1” for Stage 2 kits, +3” can be used while towing.
