Motorcycle Fork Cartridge Rod Parts

Motorbike front forks aren't just the two tubes you see on the outside - they often feature a separate internal cartridge that does the real work. See our technical article on closed vs open chamber forks for more info. Because of the difference in complexity they have different servicing costs too. The shaft that slides inside the middle of this cartridge, with the reb adjuster assembly connected to the bottom and damping piston parts attached to the top, is called the fork cartridge rod.

In a traditional oil / spring fork leg this assembly creates the rebound damping. The clickers press on the inner pushrod which adjusts the flow of fluid through the piston and shim stack held onto the end of the rod - learn more on how to use them in our damping adjusters article.

We sell all the individual parts for suspension tuners as well as complete OEM replacement assemblies. If you want to improve the damping of your cartridge forks you can try one of our performance revalving kits, or if you are a pro with a suspension dyno you can mix up your own valving shims stack from a huge variety of sizes and thicknesses.
