3x6x3.0mm Black Aluminium Shim (8pcs) - Yokomo YOKZCA3630B  [YOKZCA3630B]

Fine-spacing aluminium shims for model setup

Included are eight precision-cut aluminium shims sized 3x6x3.0mm intended for radio controlled models. The black anodised finish reduces surface wear while keeping thickness consistent for repeatable adjustments. Fit these shims where controlled spacing or preload changes are required.

Application notes: use shims as thin spacers between bearings, shafts, hubs, or mount points to address axial slack, refine gear mesh, or align components. Each shim is a fixed 3.0mm thickness so stacking options let you obtain intermediate clearances without modifying parts.

Installation tips: clean mating surfaces to prevent trapped debris during fitting, align shim edges flush with housings to avoid interference, and recheck clearances after tightening hardware. Consider threadlocker or locknuts in areas exposed to vibration.

Tuning function: aluminium shims offer predictable spacing shifts useful when dialing in chassis geometry and driveline behaviour, for example reducing binding or recentring rotating assemblies without altering fixed parts.
