Precision Pinion for Consistent Track Performance

The Arrowmax AM-348042 pinion is built for hobbyists who want dependable gearing on race day. Machined from 7075 aluminum, it balances toughness with reduced rotating mass to help maintain consistent acceleration.

Advantages of the 48P 42T Option

The 48P 42T tooth count gives a useful step in tuning overall drive ratio, helping you trade top speed for improved low-end response or vice versa. It is a flexible choice when adjusting gear ratios across different setups.

Durability and Lightweight Construction

Using hardened 7075 aluminum results in a pinion that resists deformation while keeping weight down. That combination helps preserve gear mesh and supports efficient motor performance over long runs.

Will this pinion fit my model's motor shaft?

You should verify your motor shaft diameter and gear pitch before fitting. The 48P pitch is specific, so confirm shaft bore and key or grub screw style to ensure a secure mount.

Any tips for installing the pinion correctly?

Set the gear mesh using shims or the motor mount, check backlash, and tighten the pinion fastening as recommended by your model manual. Proper mesh prevents premature wear.

How should I inspect and maintain this gear?

Regularly clean the gear and inspect tooth faces for burrs or rounded edges. Replace the pinion if you notice significant wear and keep the drive train properly lubricated where applicable.
