3Racing 3RAC-PG4837 durable 48 pitch pinion

If you are replacing a worn pinion or tuning a drivetrain, the 3Racing 48 Pitch 37T Pinion Gear is a practical option. Made from 7075 aluminium, it offers strong mechanical properties while remaining lightweight. The hard coating helps guard against tooth wear, lengthening usable life between replacements.

Key advantages of the 3Racing 48 Pitch Pinion

Material Strength: 7075 aluminium gives a good balance of stiffness and low weight.
Protective Coating: Hard coating helps reduce abrasive wear on the gear teeth.
Precise Tooth Geometry: Promotes steady meshing and efficient torque transfer.
Multi Use: Handy as a spare or upgrade across many 48 pitch applications.

Will this fit my existing spur gear?

It pairs with spur gears using 48 pitch geometry; confirm tooth count and pitch match before fitting.

Is any bedding in required after fitting?

No special bedding in is required, but check mesh and run the drivetrain at low speed initially to verify smooth engagement.

When should I replace the pinion?

Replace it if you notice visible tooth wear, uneven contact patterns, or increased noise from the gearbox.
