Precision shim pack for smooth diffs - Tamiya 54589 RC Gear Differential Shim Set 8pcs OP-1589  [54589]

Fine-tune differential clearance with Tamiya shims

The Tamiya 54589 Gear Differential Shim Set gives hobbyists a simple way to dial in gear clearance on oil-filled gear differentials. The pack contains two shim thicknesses, 0.2mm and 0.3mm, so you can tweak bevel gear engagement to suit driving style and lubricant choice. These parts are intended for Tamiya 4WD touring cars and off-road buggies that use sealed gear diff assemblies.

Pack contents and shim sizing

This kit includes eight 5x10x0.2mm shims and eight 5x10x0.3mm shims, providing a balance of fine and slightly thicker spacers. By combining shims you can precisely set gear mesh, reduce play, and promote smoother operation while limiting premature wear when running on different surfaces.

Where to use these shims

Use these shims in compatible Tamiya 4WD touring and off-road models to adapt the differential for tight on-road tracks or looser off-road conditions. Adjusting shim stack height can improve drivetrain feel and extend the service life of bevel gears in oil-filled units.
