Compatible YZ-4S Slipper Collar - Yokomo S4-303CA Aluminum Replacement  [S4-303CA]

Slipper collar fitment for YZ-4S platforms

This aluminium collar is supplied as an RC-scale replacement for the slipper assembly on Yokomo YZ-4S related platforms and the compatible YZ-4SF standard parts. It is intended to give a reliable seating surface for the slipper pad or clutch interface, helping to preserve constant engagement during setup changes and circuit running.

Installation is straightforward when following the car's established slipper assembly order, since the collar takes the place of the original collar without altering the rest of the slipper stack. Use cautious preload settings and evaluate slip characteristics in practice runs to dial in the preferred drive response; the aluminium construction keeps geometry stable under load and reduces deformation when compared to softer materials.

Offered as an aftermarket RC accessory, the part's purpose is to provide consistent support for slipper pads and to help maintain repeatable friction behaviour during servicing and setup work.
