Consistent Pinion for Everyday Tuning

The 3Racing 48 pitch 31 tooth pinion, model 3RAC-PG4831, is built for hobbyists who adjust gearing regularly. Forged from 7075 aluminium and treated with a hard coating, it delivers dependable longevity and smoother engagement across varied running surfaces.

Engineered to Reduce Wear

The durable 7075 aluminium core combined with a hard surface finish helps the pinion retain tooth shape during extended use. This reduces the need for frequent replacements and keeps gear mesh stable session after session.

Good Choice for Multiple RC Types

Designed as a 48 pitch, 31 tooth pinion, it works with many compatible spurs and is a useful spare when you are adjusting ratios for grip or top speed. Confirm spur and shaft specs before fitting to your model.

Can I run this pinion on both on-road and off-road cars?

Yes, the 48 pitch 31T form factor suits many on-road and off-road setups, provided the spur gear and shaft match the same pitch and diameter.

Does the material affect gear noise?

7075 aluminium with a hard coating tends to run quieter than worn or softer gears because it holds tooth form better and keeps mesh consistent.

How often should I inspect the pinion?

Check the pinion for nicks and wear after a few runs when new, then include it in routine checks after any heavy use or if you notice slippage or noise.
