Tamiya 33T 48Pitch Over Ratio Spur Gear O-AP0001 for M Series  [FP-O-AP0001]

Compact 33T 48 Pitch Spur for Tamiya M Series Setups

The Factory Pro over ratio spur is an aftermarket replacement aimed at hobbyists who want to refine drive ratios on mini touring and compact RC platforms. It meets 48 pitch standards and adds a 33 tooth spur to alter final drive characteristics without swapping wheels or motors.

Compatibility is indicated for T.O.P. FD Mini and the Tamiya M Series range, notably M05, M06, M07 and M08. Confirm your gearbox accepts a 48 pitch spur and the 33T tooth count before fitting. The part number O-AP0001 is provided for fitment checks.

Installation guidance: check and set pinion to spur mesh with even clearance, ensure there is no interference with the housing or adjacent parts, and secure the spur following your chassis' original fastener routine. Test on the bench first to review noise, smoothness and motor load.

Best used for small over-ratio adjustments while keeping a 48 pitch drivetrain; always verify mesh and run brief tests to assess handling and component temperatures.
