Compact 48 Pitch 39T Pinion by 3Racing

The 3Racing 3RAC-PG4839 pinion is crafted from 7075 aluminium to provide a lightweight yet robust replacement option. A hard coating is applied to improve wear resistance so the gear maintains consistent mesh under regular running conditions.

Why Choose This Pinion for Tuning

With 39 teeth, this pinion lets you adjust final drive ratios to favour acceleration or top speed depending on your setup. It is compatible with standard 48 pitch gears and the hard coated surface helps reduce tooth wear for longer service life.

Can I swap this into my existing gearbox easily?

Yes, the 3Racing 3RAC-PG4839 is intended for standard 48 pitch systems and will install like a typical pinion when the bore size and grub screw align with your motor shaft.

Does the coating affect gear mesh adjustment?

The coating is thin and should not significantly change mesh settings, but it is good practice to check and fine tune pinion to spur engagement after fitting.

Is this pinion suitable for bashing as well as racing?

Its 7075 aluminium construction gives a solid balance of strength and weight, so it performs well for both club racing and general hobby use, though heavy impacts can still damage any aluminium gear.
