Race-Oriented Pinion for Setup Precision

The 3Racing 3RAC-PG4842 pinion is a 48 pitch, 42-tooth component produced from 7075 aluminum and finished with a hard coating to preserve the tooth geometry under repeated load cycles. Its construction supports accurate gear mesh and consistent torque transfer, making it appropriate for competitive tuning and iterative gear ratio changes.

How does tooth count affect track performance?

Tooth count directly alters final drive ratio; the 42T pinion balances acceleration and top speed for many layouts, allowing fine tuning when paired with different spur sizes.

What setup checks are recommended after fitting this pinion?

Verify axial play, set motor height for correct mesh using a feeler or paper method, and confirm the set screw torque. Recheck after a short run to ensure nothing has shifted.

Are there tuning considerations for brushless power with this pinion?

With higher torque brushless systems, maintain precise mesh and consider incremental changes in pinion or spur size to control motor load and prevent premature wear even with the hard coating.
