High-Precision Pinion for Serious RC Builds

Upgrade drivetrain reliability with the 3Racing 48 Pitch Pinion Gear, model 3RAC-PG4842. This 42-tooth pinion is made from 7075 aluminum and finished with a hard coating to resist wear while maintaining smooth power transfer in club-level and weekend rigs. It is well suited for users wanting a sturdy, long-lasting gear that preserves gear mesh and efficiency.

What is the pinion made from and why does it matter?

The pinion uses 7075 aluminum, a strong lightweight alloy that helps reduce rotating mass while keeping sufficient strength for typical RC motor loads.

How does the hard coating affect performance?

The hard coating limits surface wear and helps the gear keep its tooth profile under repeated use, extending service life compared to uncoated aluminum pinions.

Will this pinion fit my motor and spur gear?

Check that your motor uses 48 pitch gearing and that the shaft and set screw arrangement match the 42T pinion. Proper mesh and shimming ensure quiet operation and longevity.
