Install the Tamiya TT02 42P 69T Delrin Spur Gear by GPM DTT2069T to achieve a more consistent mesh and quieter running. The 69-tooth, 42 pitch Delrin gear gives predictable engagement and strong wear resistance, making it a sensible choice for drivers tuning their TT02 for competition or regular use. The upgrade helps you maintain smoother acceleration and reduced gear backlash.
