Tamiya 53965 48P Pinion Duo for TRF501X and DB01  [53965]

Race oriented titanium pinion set from Tamiya

Designed for hobbyists who tweak gearing, the Tamiya 53965 pinion set provides reliable, low mass gearing for TRF501X and DB01 cars. The pair of 48P pinions, 18T and 19T, lets you swap ratios quickly to match track layout. Machined from titanium aluminum, these gears balance strength with reduced rotational weight.

Why choose these pinions for your chassis

The Tamiya 53965 set helps reduce rotational inertia while maintaining gear strength, which can improve throttle response and consistency. These pinions are useful when experimenting with short lap tracks or longer straights, and they pair well with additional Tamiya pinions to broaden setup choices.

Installation tips and compatibility guidance

Made to fit the TRF501X and DB01 chassis, these pinions should mesh cleanly with the correct spur gears. Keep in mind they are not compatible with the 540SH & RS-540 Sport Tuned Motor. Always verify mesh and secure pinion set screws to prevent slippage during hard runs.
