Dial In Your Gear Ratio

Refine gear selection with the Tamiya 48P Pinion Gear Set, supplied as 20 and 21 tooth aluminium pinions. These parts fit TRF501X and DB01 chassis and are designed to help modelers fine tune drive characteristics across different circuit types.

Fitment Details and Cautions

The Tamiya 53966 pinions are produced for accurate engagement and consistent performance. They allow incremental changes between torque and top end, and should not be used with the 540SH or RS-540 Sport Tuned Motor.

Complementary Parts for More Options

Use these pinions with Tamiya parts 53964 and 53965 to expand your tuning steps. They are a practical choice for racers and experienced hobbyists seeking predictable gearing changes.

Are these pinions suitable for electric touring car classes?

They are suitable where 48P pinions are permitted and the chassis uses the correct interface. Always verify class rules and confirm compatibility with your motor and gearbox before racing.

What difference will 1 tooth make on track?

A single tooth change subtly shifts the balance between acceleration and top speed. On technical tracks it can improve exit speed from corners, while on faster tracks it can slightly increase maximum speed.

How should I check gear mesh after fitting?

Fit the pinion, rotate the drivetrain and inspect for even contact along the teeth. Adjust the motor mount or use shims to achieve a close but free-running mesh, then secure fastenings and recheck.

Will these pinions wear quickly on abrasive tracks?

Aluminium pinions can show wear faster on dusty or gritty surfaces. Regular inspection and cleaning will extend life, and consider protective measures or more frequent replacement if you run on abrasive terrain.
