Motorcycle Shock Piston Rubber O-Rings

Teknik Shock Piston O-Rings

Shock Piston O-Rings

Your rear shock absorber uses a machined main piston and internal passages to control oil flow, and many OEM pistons rely on soft gapless PTFE bands. Many factory and aftermarket pistons instead use sealing rubber o-rings at each end plus a metal bushing ring with a PTFE-coated exterior. We also stock performance piston ring conversion kits and complete damping piston assemblies with rings or bands fitted.

Sealing for main piston assemblies and low-friction conversion

  • Restore oil sealing between piston and bore to prevent bypass and loss of damping
  • Reduce friction compared with worn endless bands for smoother action
  • Extend service life when used with PTFE-coated metal bushings
  • Compatible with valving stacks and shim-based damping systems

Recommended Pairings

Consider matching o-ring replacement with Suspension Tools and check valving shims and locknuts: valving shims, locknuts, plus our DIY damping adjustment guide and shim equivalence calculator.
