Motorcycle Shock Piston Sealing Bands

Teknik Shock Piston Band

Shock Piston Band

Your rear shock absorber contains a machined metal piston with precision passages; many OEM main pistons use soft gapless PTFE bands to seal the outer diameter. These bands can add friction and wear, so some factory shocks and aftermarket designs use sealing rubber o-rings plus a metal bushing ring with a Teflon-coated exterior for lower friction and longer life.

Sealing and friction control inside your rear shock

  • Reliable sealing of piston passages with PTFE endless bands for original-fit applications
  • Upgrade options to low-friction piston ring conversion kits using sealing rubber o-rings and Teflon-coated bushings
  • Swap to complete damping piston assemblies with rings pre-installed for easy rebuilds
  • Maintain correct damping stacks with compatible valving shims and secure with locknuts

Recommended Pairings

Consider matching piston band work with Suspension Tools and consult our shim equivalence calculator or DIY damping adjustment guide when rebuilding.
