Yokomo Z4-300RFS YZ-4 Rear Mount Front Spacer Set  [Z4-300RFS]

YZ-4 rear mount front spacer for setup

The supplied spacer set mounts on the front-facing side of the YZ-4 rear suspension bracket and serves as an upgrade or replacement accessory for precise RC tuning. These shims change the clearance at the mount interface, giving you control over how the rear suspension sits relative to the chassis.

Fitting is simple: position the spacers at the front side of the rear mount where the existing fasteners hold components together. The parts are intended to be used with the original mount assembly; after fitting, check that seating is secure and that suspension links retain free movement.

Consider the spacer set a fine-tuning geometry tool rather than a main suspension component. Adjusting thickness or stacking spacers alters the mount spacing and can influence rear roll characteristics, preload and pivot placement; monitor component condition and evaluate changes progressively.
