Motorcycle Shock Shaft & Internals 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.
The damper shaft looks simple, but is full of inner components - the rebound adjuster presses on a pushrod that slides around inside that main damping shaft, with tiny guides, bushes, o-rings, spacers, clips and an angled end needle used to adjust valve pressure.
These OEM assembled shock shafts include the internal small components pre-installed inside - but do not include the lower attachment lug and rebound clicker from the base, or the mounting bearings parts. Remember that the bearing & seal need regular servicing too!

We also stock bare chromed tubes with no internals or full rod & eye assemblies.
If your motorcycle shocks are rebuildable (not all of them are - see our FAQ on shock servicing) and have rebound adjustment, you will usually find it inside the end eye assembly. This clevis or yoke then bolts to the rear swingarm or suspension link via bearings & grease seals to keep the whole suspension moving smoothly. They look simple, but are often full of small clicker parts! Find out how to use those clickers effectively in our DIY damping adjustment guide.
