Push Industries ACS3 Coil Conversion Kit Fox 36 2021+

SPECIAL NOTE: Installing the ACS3 Coil Conversion kit will VOID the 1-year Fox Factory warranty. The kit does not pose any structural/safety threat to the Fox fork, but since it is not built by Fox, the warranty will be voided on your fork. Switching back to the stock air assembly is also not recommended after converting your fork to the ACS3 Coil. Not compatible with 36 Rythm or 36 E-Bike Forks.


The ACS3 also features a pneumatic bump stop, adjustable between 5 - 50 psi. This effectively acts like bottom-out spacers in an air fork, adjusting the amount of ramp-up, or bottom-out resistance. Simply use a standard shock pump to set your bump stop pressure from the top cap of the system. This air cap is not to be confused with the air cap you're used to on your air-sprung fork. The ACS3 is available for rider weights 125 - 230 lbs, in 15 lb increments. Inside each of these increments are varying weights of coil springs, which will be required to make the fork feel right for you. Springs are available separately, should you need to change them at any point.
