Precision Pinion for Accurate Gear Ratios

The 3Racing 3RAC-PG4842 pinion delivers a 42-tooth 48 pitch option made from 7075 aluminium and finished with a hard coating to protect tooth edges. It is aimed at builders seeking consistent gear engagement and dependable power transfer for tuning and setup work.

What pitch and tooth count does this pinion use?

This unit is 48 pitch with 42 teeth, suitable for matching with 48 pitch spur gears to achieve the intended overall ratio.

Is 7075 aluminium strong enough for high power setups?

7075 aluminium offers a good strength to weight ratio for many hobby applications; the hard coating further protects the tooth surfaces, though extremely high power applications may still favour steel pinions.

How often should I inspect the pinion?

Inspect teeth and mesh after several runs or after exposure to grit; look for rounding or pitting and correct mesh to preserve the coated surface.
