Yokomo S4-303PA Slipper Plate for YZ-4SF, aluminium slipper plate  [S4-303PA]

Slipper plate for YZ-4SF

This aluminium slipper plate is a direct replacement option intended for the YZ-4SF slipper assembly as a standard parts alternative. The part replaces the original slipper plate to provide a solid metal interface in the slipper stack, keeping work focused on predictable engagement and repeatable drivetrain response.

Installation is straightforward for those familiar with YZ-4SF maintenance, it fits the standard slipper assembly mounting points and uses the existing slipper hardware, careful alignment during assembly is recommended to avoid pre-load or lateral binding. The plate is intended for tuning purposes, not to change gear ratios or other drivetrain components.

Tuning role: swapping a metal slipper plate affects slipper feel by changing flex and wear characteristics compared with stock material, which can help crews fine-tune slip onset and traction transition on varied 1/10-scale surfaces.
