Motorcycle Fork Rebound Pistons & Rings

Motorbike front forks aren't just the two outer tubes you see - there's a separate internal cartridge doing the real work. Our closed vs open chamber article explains more - but sliding in the middle of that cartridge, with a reb adjuster assembly on the bottom & damping piston parts up top, is a fork cartridge rod.

At the top of a cartridge rod assembly is one of these rebound damping pistons & its PTFE sealing ring or band, locked onto a holder tower together with the shim stacks using a locknut.

If you're a pro with a suspension dyno you can find our valving shims in their own category - we have way too many sizes & thicknesses to list here! But if you don't have the time & equipment, you can still tune the damping of your cartridge forks using one of our performance revalving kits.

The reb adjustments are inside the axle feet at the bottom of the fork lower leg tube. The clicker presses an inner pushrod - which loosens or tightens the stack on the other end of the hollow cartridge shaft. By adjusting oil flow you change damper resistance - learn how to use your clickers.
