Yokomo YOKD064 Aluminium Spring Cup for RC Shock Assemblies  [YOKD064]

Aluminium spring cup for RC shock dampers

This Yokomo YOKD064 aluminium spring cup is an R/C damper component that secures coil springs on shock assemblies. It provides a firm seating surface so springs sit consistently when assembling or adjusting dampers for on-road and off-road models.

Compatibility is general rather than model specific: the part fits many common shock assemblies that use a separate spring cup. Before you buy, check your shock's spring seat diameter and internal shape to ensure correct fit, since sizes differ between manufacturers and chassis.

Installation is simple: slide the cup onto the shock shaft to position the spring at its intended installed height, then reassemble the shock. The aluminium construction gives a hard seating face that resists deformation during repeated servicing, helping to maintain consistent preload and end-stroke behavior while tuning.

In practical tuning the spring cup is a small but useful item: reliable seating reduces spring tilt and uneven wear, so incremental suspension adjustments become more predictable and repeatable at the workbench and on the track.
