Fine Tuning Drive Ratios for TRF501X and DB01

Upgrade your RC's gearing with the Tamiya 48P Pinion Gear Set, supplied in 20T and 21T options. Made from aluminium for durability and finished in titanium colour, these pinions are sized for the TRF501X and DB01 chassis to help you dial in acceleration and top speed for different track layouts.

Accurate Fit and Compatibility Notes

The Tamiya 53966 gears deliver accurate tooth profiles for consistent mesh and predictable performance. Choose 20T or 21T to shift the balance between torque and speed depending on your circuit. Note that these pinions are not compatible with the 540SH & RS-540 Sport Tuned Motor.

Pairing and Setup Options

These aluminium pinions work well alongside Tamiya parts 53964 and 53965 to extend tuning options. They are a practical addition for hobbyists who swap gear ratios regularly during practice sessions and club races.

Can I use these pinions with other motor types?

These pinions will work with many motors that suit the TRF501X and DB01 drivetrains, but they are explicitly not compatible with the 540SH and RS-540 Sport Tuned Motor. Check motor shaft size and spline pattern before fitting.

How do I decide between 20T and 21T for a race track?

Pick 21T for a higher top speed on fast, flowing tracks and 20T where tighter turns and quicker acceleration matter. Test both in practice to find the best trade off for your setup.

Any tips for installation and maintenance?

Ensure correct gear mesh and secure fastening to avoid slippage. Inspect for wear regularly, keep the mesh free of debris, and use a small amount of suitable grease on the bearing surfaces if recommended for your chassis.
