Tamiya T3-01 Drivetrain Tuning Gear Set - Factory Pro O-AP0004  [FP-O-AP0004]

Gearbox internal ratio tuning for T3-01

The Factory Pro O-AP0004 gear set is an aftermarket internal ratio option made for the Tamiya T3-01 chassis. It modifies how the internal gears interact so you can adjust throttle feel and low end pull while keeping the same motor pinion and spur sizes.

Installing the kit uses standard T3-01 gearbox service steps: open the case, remove the original internal gears, fit the supplied gears, confirm correct mesh and endplay, then rebuild checking bearings and shims. This set is intended for drivetrain tuning and not as a substitute for external transmission parts.
