Yokomo YOKBDS3 Aluminium Damper Retainer — RC Shock Cap Upgrade  [YOKBDS3]

Precision Aluminium Damper Retainer

The Yokomo YOKBDS3 aluminium damper retainer is an RC-scale replacement part designed to secure shock caps and retainers in small-scale damper assemblies. It is a machined aluminium component that stabilizes the interface between the shock cap and upper suspension mount without altering core damper internals.

Fit and installation are straightforward: confirm your shock cap and piston rod clearances before fitting, slide the retainer into position and secure it with the original hardware. The retainer's purpose is alignment and repeatability, helping keep the shock cap seated consistently during setup and after maintenance.

When tuning, a rigid aluminium retainer can reduce minor play at the cap interface, helping to maintain consistent oil sealing and shim stack positioning across repeated runs. Periodic checks of thread engagement and a light film of compatible lubricant on mating surfaces will preserve function and limit wear.
