Tamiya M05 M-chassis 33/21 & 35/21 fast gear set by 3Racing M05-02  [M05-02]

Fast gear set for M05

This gear set supplies alternative spur/pinion combinations for Tamiya M05 scale M-chassis tuning, offering two faster gear ratios than the stock 37/21. The set’s main ratios are 33/21 and 35/21, intended to raise top speed while requiring corresponding pinion choices and setup adjustments.

Recommended pairing details from the source data show suggested pinion ranges for each spur size: with the original 37T spur use 16T, 18T and 20T pinions; with a 35T spur use 18T, 20T and 22T pinions; with a 33T spur use 20T, 22T and 24T pinions. These groupings help you select a pinion to match desired top speed and acceleration trade-offs.

Installation notes: confirm correct gear mesh and backlash when fitting a smaller or larger spur to avoid premature wear, recheck motor load with your ESC and motor combination, and verify that drivetrain bearings and diff are serviceable before increasing ratio for sustained high-speed runs.
