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

Steel Ring and Bevel Gear Set for Tamiya TT02

This 8pcs steel ring gear and bevel gear set is an aftermarket replacement intended for Tamiya TT02 and TT02B RC chassis. Manufactured by GPM 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 improve wear resistance compared to standard plastic parts, but require correct gear mesh and bearing condition to avoid accelerated wear or noise.

Installation notes: ensure the differential carriers and bearings are clean and free of debris, set correct backlash using the chassis-specific shims or presets, and check gear concentricity under slow hand rotation before running the model. Use recommended grease sparingly on bevel gear teeth to reduce initial noise and assist bedding in.

Tuning role: swapping to steel ring and bevel gears is primarily about longevity and consistent tooth geometry under load, which helps when pursuing higher motor torque, extended running sessions, or more aggressive setup testing. Monitor noise and heat during the first runs and re-check mesh and bearing play as part of routine maintenance.

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.
