Motorcycle Shock Spring Retainer Clips

A motorbike's coilover needs to attach the coil spring to the shock absorber shaft - plus it can hold the bottoming rubber safely too - so connecting to the bottom end is a holder cup for the conical bumper.

Sat on top of that cup is one of these spring lock rings (shaped like a big cast aluminium c-clip), retaining the assembly together. It holds the spring concentric around the shock body so they never rub during suspension travel, locking in place using the spring's pre load pressure. There is a gap in the outer diameter of the retainer to fit around the main damper rod as it slides into place while replacing shock springs.

A perch or seat often sits above to distribute force evenly, acting as a spacer washer too - see our spring rate, preload & sag article. 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.
