Race-Grade Pinion with Consistent Engagement

The 3Racing 48 Pitch Pinion Gear 43T (3RAC-PG4843) is manufactured from 7075 aluminium and finished with a hard coat to preserve tooth geometry under repeated loads. This pinion aims to deliver steady mesh characteristics suitable for race tuning and setup work.

Material and Surface Integrity

Using 7075 aluminium yields a strong, lightweight component while the hard coating reduces surface wear that can alter contact patterns. The result is a pinion that maintains predictable engagement across multiple runs.

Setup and Tuning Considerations

The 43-tooth option gives fine control over final gearing for competitive adjustments. When installing, ensure axial alignment and secure fixation to prevent slippage and to protect the coated surfaces from unnecessary abrasion.

What are the key checks after fitting this pinion?

Verify axial runout, confirm correct mesh depth with the mating spur, and ensure grub screws or set collars are torqued to prevent movement during high load conditions.

How does the coating affect long term tooth form?

The hard coating resists surface wear that can change contact patterns, helping the pinion hold its original tooth form and maintain reliable contact with the spur over time.

Is this suitable for high RPM motors?

It is appropriate for many tuned motors provided the overall drivetrain is set up correctly and mesh is checked after changes; monitor temperatures and wear when running high RPM applications.
