Fox

Piston Shaft, 55mm, Black

Fox Piston Shaft (55mm, Black) is a direct replacement piston/damper shaft for compatible Fox rear shocks, designed for damper rebuilds where the original shaft is worn, scored, or damaged. Replacing the shaft helps restore consistent oil control and predictable damping feel, supporting smoother performance and longer service life after a full shock service.

• 55mm Shaft Length - Correct sizing for specific Fox rear shock damper assemblies; helps ensure proper internal fit and function
• Piston + Damper Shaft Assembly - Replaces a critical wear component that directly affects damping consistency and oil sealing performance
• Black Finish - Matches common OE appearance and aids clean identification during service
• Service-Rebuild Focused - Ideal when a shaft shows scoring or corrosion that can accelerate seal wear and compromise damper performance
• Compatibility Check Recommended - Confirm exact shock model/series and shaft length before ordering for a trouble-free rebuild
