Tamiya TT02 Ring & Bevel Gear 8pc Set TT2100 for Tuning by GPM  [TT2100]

Steel ring and bevel gear upgrade for TT02 platforms

This 8pcs steel ring gear and bevel gear set is an aftermarket replacement intended for Tamiya TT02 and TT02B chassis. Supplied as model TT2100, the components replace stock plastic gears in the differential and intermediate drive locations used on the TT02 series. The text here is limited to RC hobby maintenance and tuning use.

Compatibility is restricted to the TT02 platform as listed; confirm gearbox and differential housing clearances before finishing assembly. Steel gears deliver improved wear resistance compared with standard plastic parts, but require accurate mesh and good bearing condition to prevent excess noise or premature wear.

Installation notes: make sure differential carriers and bearings are free of debris, set correct backlash with the chassis-specific shims or spacers, and inspect gear concentricity by slow manual rotation before running. Use a light coating of grease on bevel teeth to aid bedding in and reduce initial noise.

Tuning role: fitting steel ring and bevel gears prioritises longevity and stable tooth geometry under load, which supports higher torque settings, extended runs, or more demanding setup tests. After initial runs check for noise, heat, and any change in mesh or bearing play as part of normal servicing.

Use this set when you need steel spare gears for TT02 models to support heavier use and focused tuning work, and always follow chassis-specific guidance for correct mesh and bearing checks.
