Motorcycle Shock Piston Sealing Bands

Your rear shock absorber has a complex internal thick metal disc with machined passages flowing between both flat sides, and to make sure the suspension fluid can only flow through these holes, many OEM main pistons use soft gapless PTFE bands to seal around the outer diameter.

These are well priced, but they have more friction & wear faster, so some rare factory shocks & many aftermarket designs use a combination of sealing rubber o-rings at each end plus a metal bushing ring with teflon coating on the exterior surface in between.

We carry a range of performance piston ring conversion kits if you want to upgrade from your sticky endless band, or we also offer damping piston assemblies with the rings or bands already installed.
