Tamiya TT02 Steel Ring & Bevel Gear Set 8pcs TT2100 by GPM  [TT2100]

High-duty steel ring and bevel gears for TT02 use

This 8pcs steel ring gear and bevel gear set serves as an aftermarket replacement for Tamiya TT02 and TT02B chassis. Supplied as model TT2100, the kit fits the differential and intermediate drive areas where the TT02 platform typically uses those components. The content here applies to RC hobby use and spare-part replacement for maintenance or tuning.

Compatibility is centred on the TT02 family; installers must confirm that gearbox and differential housings match the parts before completing assembly. Steel components resist wear better than factory plastics, but require proper mesh and sound bearings to avoid increased wear or drivetrain vibration.

Fitting tips: keep differential carriers and bearings clean, set backlash using the correct shims or presets, and slowly rotate the gears by hand to verify smooth engagement prior to powering the model. A light smear of grease on bevel teeth helps with initial bedding and reduces run-in noise.

Tuning impact: installing steel ring and bevel gears improves tooth stability under load, useful when increasing motor torque or running longer sessions for setup work. After the first runs, monitor for unusual noise or heat and re-inspect gear mesh and bearing play as part of planned maintenance.

Select this steel gear set for TT02 platforms when durability and stable tooth geometry matter, and follow chassis-specific guidance for correct installation.
