Adjustable bevel gear shim set - Tamiya 54589 RC Gear Differential Shim Set 8pcs OP-1589  [54589]

Get accurate gear mesh using Tamiya shim spacers

The Tamiya 54589 Gear Differential Shim Set provides the shims needed to set precise clearances inside oil-filled gear diffs. Offering 0.2mm and 0.3mm thicknesses, the shims help tune bevel gear contact for smoother rotation and controlled backlash. These spacers suit Tamiya 4WD touring cars and off-road buggies using the standard oil-filled differential layout.

Shim breakdown and tuning tips

The pack supplies eight 5x10x0.2mm shims and eight 5x10x0.3mm shims so you can mix stacks to achieve the desired mesh. Small adjustments can reduce noise, prevent uneven wear, and improve drivetrain efficiency across different track surfaces.

Ideal use cases for 4WD setups

These shims are intended for fine adjustment in Tamiya 4WD touring and buggy platforms. Whether you are chasing consistent lap times or improving everyday handling, correct shim spacing helps maintain reliable performance in oil-filled differentials.
