Yokomo YOKD064 Aluminium Spring Cup - Damper Spring Retainer for RC Shock Assemblies  [YOKD064]

Aluminium spring cup for RC dampers

This Yokomo YOKD064 aluminium spring cup is an R/C scale damper part intended to retain coil springs on shock assemblies. Its role is purely to provide a stable seat for the spring, improving repeatability when assembling or adjusting dampers for on‑road or off‑road models.

Compatibility is general rather than model‑specific: the part suits many common shock assemblies that use a separate spring cup design. Before ordering, check your shock’s spring seat diameter and internal geometry to confirm fit, since dimensions vary between manufacturers and chassis.

Installation is straightforward: slide the cup onto the shock shaft to locate the spring at its correct installed height, then reassemble the shock. The aluminium material offers a hard seating surface that resists deformation under repeated assembly, which helps maintain consistent preload and end‑stroke behaviour during tuning cycles.

In tuning practice the spring cup is a small but useful component: consistent seating reduces spring tilt and uneven wear, making incremental suspension adjustments more predictable and reproducible on the setup bench and at the track.
