Motorcycle Shock Shaft & Mounting Lug Assembly

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).

These KYB and Showa OEM rod assemblies include all the internal push rod & small components installed inside the shock shaft, plus the lower attachment lug with rebound clicker bolted onto the base. Mounting bearings are not included, but sold as separate parts or as our chassis bearing kits. Remember that the bearing & seal need regular servicing too!

If your motorcycle shocks have rebound adjustment you will usually find it inside this end eye assembly which then bolts to the rear swingarm or suspension link via bearings & 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 damper 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 - these full rod and eye assemblies, assembled damping shaft with internal parts pre-installed, or bare chromed tubes with no internals.
