Durable Pinion for Precise Power Transfer

The Arrowmax AM-348039 pinion offers a robust, precisely cut option for RC drivetrains. Built from 7075 aluminium, it balances durability with a lightweight profile to help maintain consistent gear contact. With a 48P pitch and 39 teeth, it integrates into many common gearsets for smooth power delivery.

Precision Machining Reduces Wear

Careful machining of the tooth form on this 7075 pinion encourages even load distribution across the gear mesh. That accurate profile helps reduce uneven wear and supports longer service intervals when paired with a correctly matched spur gear.

Fitment and Easy Swap

The 48P 39T specification makes the pinion a versatile choice for model upgrades and repairs. Swapping this gear is straightforward when your model uses standard 48-pitch components, allowing quick changes trackside.

How do I verify fit before buying?

Confirm your vehicle uses 48-pitch gears and a 39-tooth pinion option, and check motor shaft diameter and mounting to ensure proper fit.

Can this pinion be used to alter gear ratio?

Changing to a 39T pinion will alter your overall gear ratio within 48-pitch systems, allowing fine tuning of acceleration and top speed depending on the rest of your drivetrain.
