Tamiya TT01 Bronze Collars and Shims by GPM TT056D/ACC  [TT056D/ACC]

Bronze collars and shims for TT01

This is an RC-scale set of bronze collars and shims produced by GPM for use with the Tamiya TT01 platform. The components act as precision spacers and locating collars to control lateral play and axial positioning of shafts and bearings on the TT01 chassis.

Use these parts to fine-tune axle spacing, reduce unwanted side play, and achieve more consistent bearing preload where metal-to-metal fit is preferred. Because they are bronze, they give a durable bearing surface and predictable fit compared with generic soft spacers.

Installation is straightforward: place collars or shims between bearing faces, hubs, or mating shafts to obtain the target clearance. The parts are intended for hobby-grade RC assembly and tuning on TT01 series cars and should be inspected for fit before permanent assembly.
