Motorbike front forks are not just the outer tubes — an internal cartridge does the real work. Sliding in the middle of that cartridge, with a rebound adjuster assembly on the bottom and damping piston parts up top, a fork cartridge rod transfers damping forces. These genuine KYB & Showa OEM alloy shafts are sold naked; the rebound piston holder tower, damping piston parts and pre-assembled complete fork cartridge rod are available separately. Read about closed vs open chamber designs in our technical article and clicker use in our damping adjusters article. We also stock performance revalving kits and valving shims for tuners.
Consider matching cartridge rods with Suspension Tools for accurate rebuilds and tuning.
Browse genuine KYB and Showa cartridge shafts and matching components to complete your fork rebuild or upgrade.
