Slipper Collar for YZ-4S Compatible with Yokomo S4-303CA  [S4-303CA]

Precision collar for the slipper assembly

This aluminium collar is a scale replacement designed for the slipper assembly found on Yokomo YZ-4S derived platforms and the compatible YZ-4SF standard components. It creates a dependable seating surface for the slipper pad or clutch interface and helps preserve steady engagement during setup variations and active running.

Mounting is direct when you follow the vehicle's existing slipper stack arrangement; the collar replaces the stock collar element and leaves the rest of the stack unchanged. Use modest preload settings and observe slip behaviour in trial laps to confirm the targeted drive response, since the aluminium construction sustains accurate geometry under load and is less prone to compression than softer materials.

Sold as an aftermarket RC accessory, the part aims to deliver repeatable support for slipper pads and to keep friction characteristics stable through maintenance and tune sessions.
