Race Focused Pinion with Precision Tooth Form

The 3Racing 64 Pitch Pinion Gear 46T, model 3RAC-PG6446, is designed for racers who tune gearing for lap time consistency. CNC level machining of 7075 aluminium provides dimensional stability while keeping weight to a minimum for quicker throttle response.

Coating for Sustained High Load Operation

The hard coating enhances surface hardness to reduce micro fatigue and maintain tooth geometry under repeated high torque cycles. The 64 pitch profile promotes accurate contact patches, which is critical when optimising gear ratios for competitive setups.

Practical Choice for Setup Iterations

The 46T version offers a sensible increment for gearing adjustments during practice sessions. It is simple to swap and evaluate within rolling tests, making it useful for teams refining acceleration and top speed balance.

What is the recommended method to verify mesh under race conditions?

Use gear marking compound and run the drivetrain at low load to inspect contact pattern, then lock down the pinion with the correct torque on the set screw.

How does hard coated 7075 compare to steel for competition use?

Hard coated 7075 reduces rotating mass and is kinder to spurs, allowing quicker acceleration, while steel may last longer but adds weight; choice depends on priorities.

Any setup tips for preventing premature wear?

Maintain correct backlash, check mesh after initial runs, and avoid overloading with excessively aggressive gearing to extend service life.
