Why Replace Piston Rings?

Worn piston rings allow fork oil to bypass the piston, resulting in poor damping control, harsh ride quality, and inconsistent suspension action. Fresh piston rings restore proper compression and rebound damping for predictable, confidence-inspiring performance on the track.
