Motorcycle Shock Shaft Parts

Right in the centre of your motorbike's coilover is the main damping shaft. At the top end it holds the piston inside the shock absorber body while at the bottom end it screws onto the Clevis or Yoke.

A clevis has a split fork of two tabs with a gap between them (like the diagram shown), while a yoke has just one wide ring sticking down (much like the top of a shock body).

If your damper has rebound adjustment you will usually find it inside this end eye assembly which then bolts to the rear swingarm or suspension link via bearings and grease seals to keep the whole suspension moving smoothly. Looks simple, but it's often full of small clicker parts! Find out how to use those clickers effectively in our DIY damping adjustment guide.

Although the shock shaft looks super simple, it too is full of inner components - the reb adjuster presses on a pushrod that slides around inside that main shaft, and it needs tiny guides, bushes, o-rings and an angled end needle to adjust the damping. We sell the shafts in different states of assembly depending on what you need - bare chromed tubes with no internals, assembled damping shaft with internal parts pre-installed or as a full assembly with the complete shaft bolted to the clevis or yoke (and all the rebound adjuster internals).

We sell these assemblies for most shocks, as well as the individual push rods, locknuts, rubber seals, collars, etc for easy and cheap servicing. Teknik Motorsport also sell many other shock mounting & chassis bearings - or if your bike is too tall you can install some shock lowering washers during your next rebuild.
