Competition oriented 48P pinion with precise tooth geometry

The 3Racing 48P 30T pinion is CNC finished from 7075 aluminium and treated with a hard coat to stabilise surface wear while maintaining low rotational inertia. Its accurate tooth profile supports predictable backlash and repeatable setup adjustments in race environments.

Engineered for tuning and consistent performance

The hard-coated 7075 construction gives a favourable strength to weight ratio and the surface treatment reduces abrasive wear on mating spurs. The 30 tooth option is chosen by many racers for a balanced compromise between acceleration and top speed in 48 pitch drivetrains.

Integration and setup guidance for racers

Designed to fit standard 48 pitch spur gears, the 3Racing 48P 30T Pinion Gear aids consistent mesh and vibration reduction when installed with correct shim spacing and motor alignment. Careful mesh setup and routine inspection ensure repeatable lap times and minimise unexpected drivetrain issues.

What setup steps help achieve minimal backlash?

Use thin shims and adjust motor position to achieve a slight running clearance, then confirm with marking compound to ensure uniform tooth contact across the face.

How does hard coating affect heat transfer and wear?

The coating improves surface hardness to slow abrasive wear; it does not significantly change bulk heat capacity, so monitor motor and gearbox temperatures during testing.

Are any special fasteners or tools required for installation?

Standard motor shaft grub screws and a hex driver are typically sufficient; ensure the screw seats on a flat or keyway and consider medium threadlocker for high vibration applications.

When should I replace an aluminium pinion in a race car?

Replace the pinion if you detect tooth deformation, uneven wear patterns, or if performance consistency degrades between practice runs. Routine inspection after each meeting is recommended.
