Race focused pinion with stable tooth form

The 3RACING 48 Pitch Pinion Gear 27T is produced from high strength 7075 aluminium and finished with a hard coating to improve surface hardness and reduce abrasive wear. The machining maintains tight tolerances for reliable meshing in competitive setups.

Technical benefits for tuners

This pinion delivers predictable engagement with compatible 48 pitch spurs, which helps preserve backlash settings and drivetrain efficiency under repeated high RPM loading. Tuners can use it to fine tune final drive ratios with minimal compromise to gear longevity.

Recommended installation and checks

Ensure correct bore and mounting alignment on your motor shaft, set a minimal yet safe gear mesh clearance, and inspect tooth contact patterns after a short run-in period. Proper seating and secure fastening are essential to maintain alignment during race use.

What is the ideal run-in procedure for a new pinion?

Start with conservative mesh and modest power, run for short intervals while checking for even contact and heat, then retighten and recheck mesh after cooling.

How should I verify contact pattern?

Apply gear marking compound or light paint to the pinion or spur, rotate under light load, and assess the wear band to confirm centralised tooth contact.

Are there limits to using this pinion on high torque builds?

While 7075 aluminium with hard coating is robust, extreme torque or frequent shock loads are best served by hardened steel options; evaluate application demands before committing.
