Fox 223-00-031 Plastic 2.5" Reservoir Internal Floating Piston Uses 029-00-328 O-Ring

Nylon piston fits Fox 2-1/2" ALUMINUM reservoirs. Can take the place of 805-00-079-KIT, 223-00-036, 223-00-047, 805-00-085-KIT or 805-00-066-KIT pistons, however this nylon piston does not have threads on the top side of it. It normally uses 029-00-328 o-ring or it can use 035-00-328-A quad ring. It does NOT use a wearband.

Note: When Fox switched from steel reservoirs to aluminum on their 2-1/2" shocks, all of the internal parts were also changed because the aluminum reservoir has a smaller inside diameter than the steel reservoir. This piston is too small in diameter to work on a steel reservoir.
