Off-road and track shim kit - Tamiya 54589 RC Gear Differential Shim Set 8pcs OP-1589  [54589]

Precision shim stacks for smoother bevel gear action

The Tamiya 54589 Gear Differential Shim Set is a straightforward way to refine gear engagement in oil-filled differentials. The two shim thicknesses, 0.2mm and 0.3mm, let you tweak mesh and limit unwanted play between bevel gears. These spacers are made to fit the differential assemblies used in Tamiya 4WD touring cars and off-road buggies.

Contents and practical tuning

Inside the set you will find eight 5x10x0.2mm and eight 5x10x0.3mm shims. This range allows for subtle and larger adjustments so you can set the optimal contact pattern, reduce gear lash, and help the differential run cooler under load.

Benefits for 4WD touring and buggy platforms

For Tamiya 4WD touring cars and off-road buggies, the right shim choice can improve cornering consistency and drivetrain response. Use these shims when preparing for different track types or during routine diff maintenance.
