Upgrade component for YZ-4S slipper stacks

This aluminium collar serves as an RC replacement component for the slipper assembly on Yokomo YZ-4S related platforms and supported YZ-4SF parts. It is engineered to provide a durable seating area for the slipper pad or clutch interface, helping to maintain consistent engagement through setup changes and track conditions.

Fitting is simple when you use the vehicle's existing slipper assembly layout because this collar replaces the original collar piece without affecting the remainder of the slipper stack. Apply conservative preload and run controlled tests to check slip behaviour; the aluminium body preserves alignment under load and resists distortion more than softer alternatives.

The item functions as an aftermarket accessory for model slipper systems, offering repeatable pad support and aiding consistent friction characteristics during servicing and tuning 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 benefit does an aluminium collar give for tuning?

An aluminium collar provides a firmer mounting surface so slip engagement reacts more predictably to preload and pad changes, simplifying tuning adjustments.

Will it fit both YZ-4S and YZ-4SF variants?

Yes, it is made to be compatible with the listed YZ-4S and YZ-4SF platform variants and installs into their existing slipper stacks as a direct replacement.

Any special break-in recommended?

Run a few measured laps with conservative preload to allow pads to seat correctly against the aluminium surface, then fine tune preload and pad condition to suit driving style.
