GENERAL SERVICE INFORMATION
Recommended Service Intervals
FOX™ Racing Shocks will perform the best if serviced at
regular intervals:
• Every ride - Wash and dry the vehicle and suspension
• Every 100 hours - Visually inspect shock seals
• Every 500 hours or Annually - Change shock oil and
replace seals
FOX™ SHOCK REBUILD INFORMATION
When performing maintenance on FOX™ shocks, use
the Gas Shock Recharging Kit (PN 2200421), as it
contains the necessary valves, pressure gauge, and
fittings to deflate and pressurize shocks.
WARNING
FOX™ shocks contain high pressure nitrogen gas.
Extreme caution must be used while handling and
working with FOX™ shocks and related high pressure
service equipment. The pressure must be released
from the shock before disassembly. It is strongly
recommended you wear safety glasses and ear
protection during these procedures.
TIP: Extreme cleanliness is very important during all
disassembly and reassembly operations. This prevents
dirt or foreign particles from entering the shock, which
causes premature failure.

FOX™ SHOCK DISASSEMBLY
NOTE
To prevent damage or marks to the shock, the use of

spring preload distance.
2. Thoroughly clean all shock components and shock
body prior to disassembly.
3. Back preload adjuster all the way down and carefully
remove spring retainer and spring.
4. Use the appropriate shock body holding tool
(2871071) to properly secure the shock body
assembly into a vise for service.

heavy duty pick. Discard nylon ball and replace with
