Tamiya 53966 - 48P Pinion Gear Set for TRF501X/DB01 - Aluminium 20T and 21T Set  [53966]

Gear Ratio Options for Better Lap Times

Give your model cleaner gearing choices with the Tamiya 48P Pinion Gear Set, available in 20 and 21 teeth. These aluminium pinions suit the TRF501X and DB01 frames and offer tidy, repeatable changes to acceleration and top speed characteristics.

Fitment and Limitations

The Tamiya 53966 pinions are machined for reliable tooth engagement and predictable behaviour on the track. They let you fine tune torque versus speed, but they are not suitable for the 540SH or RS-540 Sport Tuned Motor.

Combine with Other Tamiya Parts

For broader tuning choices, use these pinions with Tamiya parts 53964 and 53965. The combination provides sensible steps for gearing adjustments without radical changes to your driveline.
