Fox Air Bump Stops

Fox air bump stops replace a fixed-rate rubber or foam bump stop with an adjustable air spring, protecting shocks from bottom-out damage while noticeably improving the feel of high-speed terrain running. Unlike a rubber or foam bump stop that provides one fixed resistance no matter the load, an air bump stop builds resistance progressively as it compresses, so the transition from free travel to a protected stop is smooth instead of abrupt, a detail that matters most in high-speed desert performance where a harsh, sudden bump stop hit destroys driver confidence and produces a jarring landing.

Adjustable air pressure also means firmness can be dialed in for different loads or terrain on the fly, rather than swapping to an entirely new bump stop every time the build changes. AccuTune will help select the correct Fox air bump stop diameter and configure the appropriate air pressure for your vehicle's weight, travel, and use case.
