Compact shim set for gear diffs - Tamiya 54589 RC Gear Differential Shim Set 8pcs OP-1589  [54589]

Accurate shim tuning for oil-filled Tamiya diffs

The Tamiya 54589 Gear Differential Shim Set supplies the small spacers needed to tune bevel gear engagement in oil-filled differentials. With 0.2mm and 0.3mm shims included, you can tailor the mesh for quieter, more reliable operation. These shims are intended for use in Tamiya 4WD touring cars and off-road buggies equipped with standard oil-filled gear differentials.

What is included and why it matters

The kit contains eight 5x10x0.2mm shims and eight 5x10x0.3mm shims. This selection enables precise stacking to achieve the correct clearance, improving gear life and reducing irregular wear by ensuring even contact across the bevels.

Using shims across different track conditions

Whether you are running smooth track sessions or rough off-road laps, matching shim thickness to oil viscosity and load conditions helps maintain consistent differential performance in Tamiya 4WD platforms.
