3Racing 3RAC-PG4831 Precision 31T Pinion Gear 48P  [3RAC-PG4831]

Precision Pinion for Stable Drivetrain Performance

The 3Racing 48 pitch 31 tooth pinion, model 3RAC-PG4831, is designed to give consistent drivetrain behaviour for road and circuit use. Fabricated from 7075 aluminium and finished with a hard coating, the pinion aims to extend service life while maintaining accurate tooth engagement.

Materials That Keep Shape

7075 aluminium provides high strength and the hard surface finish helps the pinion resist the small-scale wear that alters mesh over time. That stability is important when you are running repeated sessions or fine tuning gearing.

Practical Compatibility Guidance

As a 48 pitch, 31 tooth unit, this pinion pairs with corresponding spurs and is suitable for many popular setups. Always double check pitch, bore and shaft size before fitting to ensure correct operation.
