Compact Race Pinion for Track and Trail

The 3Racing 3RAC-PG4842 pinion is a 48 pitch, 42 tooth unit made from 7075 aluminum and treated with a hard coating to stand up to abrasive conditions. Its finish helps maintain tooth integrity so power moves cleanly through the drivetrain, making it a sensible choice for both track days and rougher running surfaces.

Is this pinion suitable for competition use?

Yes, its 7075 aluminum core and hard coating give it a balance of lightness and wear resistance suitable for competitive club racing when fitted correctly.

How should I check gear mesh with this pinion?

Fit the pinion to the motor shaft, install the spur, then use the standard paper method or a shim to set a minimal clearance ensuring minimal noise and no binding.

What maintenance keeps this pinion lasting longer?

Regular inspection for rounded teeth, correct mesh, and cleaning grit from the gearing will preserve the hard coating and extend service life.
