Race oriented 64 pitch pinion for tuning precision

The 3RACING 64 Pitch Pinion Gear 28T is produced to suit competitors who demand predictable tooth engagement and extended surface life. Forged from 7075 aluminium and finished with a hard coat, it balances strength with minimal rotating inertia for quicker spool up.

Setup and tuning advantages

Ideal for racers adjusting final drive ratios, the trimmed mass helps with transient response while the hardened surface reduces micro pitting under high torque and RPM. This makes it a solid option for tight race setups where consistency lap to lap is critical.

Compatibility and application notes

Cut to standard 64 pitch specifications, the 28T pinion suits most 1/10 scale racing spurs and allows easy ratio swaps for track specific gearing. Ensure correct mesh and consider motor timing and cooling when running aggressive setups.

What is the recommended mesh procedure for race setups?

Use a thickness gauge or the paper method to get a precise contact pattern, then lock the motor mount and recheck under load to prevent movement during heats.

Will the hard coating reduce the need for frequent gear changes?

The coating increases surface durability and can extend service life, but high power race conditions still require regular inspection for chatter and tooth deformation.

Any advice for high torque brushless motors?

For high torque applications maintain a conservative mesh, monitor motor temps, and consider incremental ratio changes to avoid overstressing the drivetrain.
