Race oriented 48 pitch 15T pinion from 3Racing

Designed with competitive tuning in mind, the 3RACING 3RAC-PG4815 48 Pitch 15T pinion combines 7075 aluminium strength with a hard coating to preserve tooth geometry under aggressive use. This unit targets consistent mesh and minimal deformation during high RPM operation.

Material choice for performance applications

7075 aluminium delivers a high stiffness to weight ratio important for race parts, helping the pinion maintain concentricity and resist mechanical fatigue. The hard coating improves surface hardness to slow wear progression under intense running.

Integration into tuned drivetrains

Suitable for 48 pitch racing gearsets, this pinion supports precise ratio adjustments for on-track tuning. Install with correctly matched spur gear and verify mesh under load to extract predictable lap-to-lap behaviour.

How does the hard coating affect wear under race conditions?

The coating increases surface hardness, reducing abrasive wear and helping the pinion retain profile during repeated high load cycles typical in racing.

Any setup suggestions for tuning with this pinion?

Start with correct mesh and run incremental pinion changes to assess acceleration versus top speed. Monitor spur condition and gearbox temperatures during tuning.

What checks should be done after initial runs?

Inspect tooth edges for chipping, confirm mesh marks align across the gear face and recheck mounting security. Replace if excessive wear or damage is present.
