Technical Summary for the 3RACING 48 Pitch 38T Pinion

The 3RACING 48 Pitch Pinion Gear 38T is produced from 7075 aluminium and supplied with a hard coating to enhance surface durability during competitive use. Its construction aims to maintain accurate tooth profiles under sustained loading in tuned drivetrains.

Materials and Finish

Forged from 7075 aluminium, the pinion balances stiffness and mass to limit rotational inertia while resisting deformation. The hard coating improves abrasion resistance to preserve mesh integrity across repeated runs.

Installation and Tuning Notes

Intended for 48 pitch gearsets, this 38T pinion should be matched carefully to the spur gear and motor shaft. Achieve correct backlash with standard paper or shim methods, and verify mesh under load before race use. Replace if tooth profile shows rounding or surface pitting.

Verify bore alignment and tighten fixings, then run the drivetrain at low speed to confirm the mesh is stable. Recheck after a short break-in run.
Yes, provided the bore and mounting method are compatible. Ensure the gearset is correctly cooled and lubricated under high RPM operation to reduce wear.
Monitor tooth profiles after each event; replace when any loss of profile, visible scuffing, or repeated mesh noise appears to prevent secondary damage to spur gears.
