Fine Adjustment Pinion from 3Racing 7075 Alloy

The 3Racing 48 Pitch Pinion Gear 45T, model 3RAC-PG4845, is built from durable 7075 aluminium and finished with a hard coating to resist wear. This 45-tooth pinion is aimed at hobbyists who want accurate increments when dialing in speed and torque for track setups, helping maintain consistent gearing under repeated use.

Features Overview

Material: Constructed from 7075 aluminium for solid strength.
Coating: Hard-coated surface to reduce surface wear.
Tooth Count: 45T for precise step changes in gearing.
Compatibility: Designed for RC drivetrains that use 48 pitch pinions.
Application: Suited to tuning and setup adjustments in competitive club racing.

Is this pinion suitable for high top speed setups?

Yes. The hard-coated 7075 aluminium construction helps handle stresses typical of higher speed gearing when paired with a compatible spur and drivetrain.

How should I inspect the gear for wear?

Check teeth edges and the bore for scoring after each race day, and clean debris before re-oiling or reassembly to prolong life.

Will this fit my 48 pitch motor pinion location?

If your drivetrain specifies 48 pitch pinions and the motor mount accepts a 45T pinion, this unit will fit; confirm shaft size and set screw type before installation.
