Tamiya TT01 Precision Collars and Shim Pack TT056D/ACC by GPM  [TT056D/ACC]

Precision collars and shims for TT01 chassis

This RC-scale pack contains bronze collars and shims intended for use with the Tamiya TT01 platform. The parts act as precision spacers and locating collars to control lateral movement and axial placement of shafts and bearings on TT01 cars.

Use the set to fine-tune axle alignment, lower unwanted side play, and establish consistent bearing preload when a firm metal-to-metal fit is needed. Bronze gives a durable bearing surface and predictable fit compared to softer materials.

Installation is straightforward: position collars or shims between bearing faces, hubs, or mating shafts until the target clearance is reached. Perform a trial assembly to verify fit before finalising the build.
