Yokomo YOKD064 Damper Spring Retainer Aluminium Cup for RC Shocks  [YOKD064]

Spring seating cup for shock absorbers

The Yokomo YOKD064 aluminium spring cup is an R/C damper part that retains coil springs on many shock assemblies. It is intended to give a stable seat so springs install repeatably when building or tuning dampers for varied model types.

This item is broadly compatible rather than tied to a single chassis: it suits many shock designs that use a removable spring cup. Confirm the shock's spring seat diameter and the cup's internal form against your existing parts since manufacturers use different dimensions.

Fitting is straightforward: slide the cup onto the shock shaft to locate the spring at the correct installed height, then rebuild the shock. The aluminium material supplies a hard seating surface that resists distortion during repeated assembly, helping preserve preload and end-stroke behaviour.

From a setup point of view a precision spring cup helps reduce spring lean and uneven wear, which makes small suspension adjustments more consistent and easier to reproduce trackside.
