Tamiya TT02 Steel Ring and Bevel Gear Upgrade TT2100 by GPM  [TT2100]

Long-lasting steel ring and bevel gears for TT02

This 8pcs steel ring gear and bevel gear set is an aftermarket replacement intended for Tamiya TT02 and TT02B RC chassis. Supplied as model TT2100, the kit provides steel gearing components for the differential and intermediate drive where the TT02 series uses these parts. The description here refers strictly to RC-scale use and spare-part replacement for model maintenance and tuning.

Compatibility is limited to the TT02 platform as indicated, and installers should verify fit against their gearbox and differential housings before final assembly. Steel gears increase wear resistance over stock plastic items, but correct gear mesh and healthy bearings are required to avoid premature wear or excess noise.

Installation notes: clean the differential carriers and bearings thoroughly, set backlash with chassis-specific shims or presets, and check concentric rotation by hand before powering the model. Apply light gear grease to bevel teeth during initial bedding to reduce running-in noise.

Tuning role: moving to steel ring and bevel gears focuses on longevity and maintaining tooth geometry under higher torque or longer sessions, which benefits aggressive test setups and high-load tuning. Monitor temperature and noise on first runs and re-check mesh and bearing play as part of routine service.

Choose this set when you need steel spare gears for TT02 platforms to support extended use and tuning work, and follow chassis-specific procedures for gear mesh and bearing checks during installation.
