Aluminum 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 component provides a robust seating surface where the slipper pad or clutch interface mounts, helping maintain consistent slipper engagement through setup changes and track use.

Installation follows the existing slipper assembly layout on the car, as this collar takes the place of the original collar element without altering the remainder of the slipper stack. Fit it with conservative preload and verify slip behaviour during test runs; the aluminum body retains stable geometry under load and resists deformation compared with softer materials.

This item is offered as an RC accessory for model-scale slipper systems, designed to deliver repeatable support for slipper pads and to assist in keeping friction behaviour predictable during maintenance and adjustments.

Compatibility

  • YZ-4S
  • YZ-4SF
  • B-YZ4SF
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What is the collar material and why choose it?

The collar is machined from aluminum to give a wear-resistant seating for the slipper assembly, improving dimensional stability compared with polymer alternatives.

Can I swap it into my existing slipper stack?

Yes. It is made to fit directly into the existing slipper arrangement on compatible YZ-4S and YZ-4SF assemblies as a direct replacement for the stock collar.

Does it change how I should set slipper preload?

Because the aluminum collar keeps the interface geometry firmer, you may find slip engagement more consistent; start with conservative preload settings and fine tune on the track to match your drive feel.
