Tamiya TT02/TT02B Steel Ring Gear Upgrade for Drivetrain - TT2100/G1 by GPM  [TT2100/G1]

Steel ring gear designed for TT02

This aftermarket steel ring gear is a direct-fit solution for Tamiya TT02 and TT02B platforms, supplied as 1 pcs for repair or upgrade of the model drivetrain. The hardened steel material is intended to reduce wear versus standard plastic rings while maintaining the stock mounting interface.

Fitment keeps the original gear mesh and centreline, so installation normally requires basic gearbox access and a pinion-to-spur mesh check. Follow common setup steps: set pinion engagement, confirm free rotation, and review mesh after an initial break-in run.

Tuning notes: a steel ring is helpful with increased motor power or non-standard gear ratios where plastic wear is problematic, but it can transfer extra load to the pinion and bearings. Verify your motor and bearings are suitable for the changed load profile before extended use.
