Fox

Piston Shaft, 9mm, 7.875x2.25"

Fox rear shocks rely on tight-tolerance internal parts to deliver consistent damping and reliable sealing. The Fox Piston Shaft is a direct replacement piston/damper shaft designed for Fox rear shocks, specified at 9mm with a 7.875 x 2.25 in size to match the correct internal length and stroke configuration. It’s the right choice when rebuilding a shock to restore smooth damping function and proper internal alignment after wear, damage, or contamination.
