RC Shock Cap Damper Retainer for Yokomo YOKBDS3  [YOKBDS3]

Sturdy Aluminium Shock Cap Retainer

The Yokomo YOKBDS3 aluminium damper retainer serves as an aftermarket replacement to hold shock caps and retainers in place on small RC dampers. It is a straightforward machined aluminium piece that organizes the interface between the shock cap and upper suspension mount while leaving internal damper components unchanged.

Installation is simple: verify shock cap diameter and piston rod clearance before fitting, insert the retainer, then tighten using the vehicle's existing fasteners. The retainer enhances alignment and repeatability so the shock cap seats reliably after setup and routine servicing.

In track or field tuning, using a rigid aluminium retainer helps limit tiny movements at the cap joint, aiding consistent oil sealing and stable shim stack behavior over multiple runs. Regular inspection of threads and light lubrication on contact surfaces will help maintain performance and reduce wear.
