Precise gear engagement from the 3RACING 3RAC-PG4840

This 3Racing 48 Pitch Pinion Gear 40T is manufactured from 7075 aluminium and treated with a hard coating to resist wear. It gives model builders a precise tooth profile that supports consistent performance in varied running conditions.

Why this pinion helps drivetrain efficiency

The hard-coated surface reduces friction and slows down wear on contact points, which keeps gear mesh stable and supports predictable power delivery during acceleration and braking phases.

Where to use this pinion

Suitable for many 1/10 scale vehicles, the pinion can be used across on-road racers and versatile off-road machines. Confirm compatibility with your spur gear pitch and mounting details for a trouble-free fit.

Is shaft size important for fitting this pinion?

Yes, matching the pinion bore to your motor shaft or adapter is essential; check the diameter and secure the pinion with the correct grub screw or clamp system.

Will changing to this pinion affect my gearing ratio?

Tooth count determines speed and torque tradeoffs. Moving to a different tooth count will change the effective gearing, so plan changes according to track layout and motor characteristics.

Any installation hints for longer life?

Ensure correct mesh, avoid overtightening fasteners, and periodically check for wear or looseness after running sessions to extend service life.
