Tamiya M05 Compatible Fast Gear Set 33/21 & 35/21 M05-02 by 3Racing  [M05-02]

M05 speed gear options

This set supplies alternate spur and pinion combinations for tuning the Tamiya M05 M-chassis, offering two faster overall ratios than the standard 37/21. The pack focuses on 33/21 and 35/21 ratio options to boost top speed while advising matching pinion choices and set-up checks.

Recommended pinion groupings are listed to guide selection: with the original 37T spur try 16T, 18T or 20T pinions; with a 35T spur try 18T, 20T or 22T; with a 33T spur try 20T, 22T or 24T. Picking the right pinion lets you dial in more speed without overloading the motor.

Installation advice: confirm correct gear mesh and backlash when changing spur size, re-evaluate motor and ESC temperatures under load, and ensure drivetrain bearings and the diff are in good order before prolonged high-speed use.
