Yokomo S4-303CA Slipper Collar for YZ-4S aluminum RC slipper collar  [S4-303CA]

Slipper collar for YZ-4S

This aluminum collar is an RC-scale replacement part intended for the slipper assembly on Yokomo YZ-4S related platforms and supported YZ-4SF standard parts. The part is designed to offer a durable seating surface where the slipper pad or clutch interface mounts, helping keep slipper engagement consistent during setup changes and track use.

Installation is straightforward when following the existing slipper assembly layout on the car, as this collar replaces the original collar element without changing the rest of the slipper stack. Use conservative preload and check slip characteristics during test runs to confirm the desired drive feel; the collar's aluminum body provides stable geometry under load and resists deformation compared with softer materials.

The component is intended purely as an RC accessory for model-scale slipper assemblies, and its role in tuning is to provide repeatable support for slipper pads and to help maintain consistent friction behaviour during maintenance and setup adjustments.
