Race-ready Arrowmax 48P 43T pinion

Serious drivers seeking a robust upgrade can rely on the Arrowmax AM-348043 48P 43T pinion gear. Manufactured from 7075 aluminium, it delivers the stiffness and low weight needed for competitive runs.

Strength and lightness of 7075 aluminium

Using 7075 aluminium gives a high strength-to-weight ratio, helping the gear resist deformation while limiting additional rotating mass. That combination supports sharp throttle control and longevity.

Balanced 48P 43T setup for handling

The 48-pitch, 43-tooth design provides a predictable gear step that helps with traction modulation and corner exits. It improves consistency in acceleration and response across different track layouts.

Easy fitment for most 48P systems

The pinion fits a broad range of 48P-compatible motors and is simple to install. Verify shaft diameter, align the pinion to the spur, and set the mesh correctly to avoid premature wear.

Is extra reinforcement needed for high torque motors?

Often no extra reinforcement is needed thanks to the 7075 aluminium strength, but on very high torque setups check for play at the motor mount and consider a hardened steel pinion if you see rapid wear.

How do I check mesh under load?

After initial setup, run the car briefly and then recheck mesh for any settling. Listen for noise and inspect teeth for even contact to ensure long life.
