Motorcycle Shock Bump Stop Guide Cup

At the bottom end of a motorbike's coilover there needs to be a way to connect the coil spring to the main shock absorber shaft - and this assembly needs to hold the bottoming rubber safely in place too.

These bumper holders attach to the base of the damper rod, transferring suspension spring travel directly to it. If your bike bottoms out, these conical stopper cups are built tough to take the force.

A lock ring (shaped like a big c-clip) is sat on top to keep the spring concentric around the shock body. This locking retainer collar is slid in while replacing shock springs. Many shocks then include a perch or seat to distribute pressure evenly, which can also act as a spacer washer to adjust pre load - learn more about spring rate, preload & sag. Some shim spacers can go at either end - see our shock spring hardware.

If your bike's coilover is consistently smashing your bump stop components, tune your compression damping first, but if it's already maxed out it might be time for a shock revalve - try our damping piston valving kits.
