This FOX Performance Elite 2.5 x 18.0 Air Shock is chosen by its dimensions rather than by vehicle. Specified at 1-5/8in shaft. The air spring is adjusted by changing the nitrogen charge pressure, which gives infinite adjustability of spring rate.
The design of the off-road Performance Elite air shock allows for infinite adjustability of the spring rate by varying the nitrogen charge pressure. FOX's first air shock was invented by Bob Fox back in 1974 and has been highly refined in the 30-plus years we’ve been producing them. The off-road Performance Elite air shock uses the identical race-proven performance damping technology as our other Performance Elite Series off-road shocks, so servicing and valving adjustments are the same.
