Stable Gear Mesh for Hobby Builds

The Arrowmax AM-348025 pinion is built for stable power transfer in 48-pitch drivetrains. With 25 teeth and precision machining from 7075 hard aluminium, it gives consistent engagement and predictable wear patterns.

Engineered for Routine Running

7075 hard aluminium provides a strong, wear-resistant surface that copes well with regular use. Its stiffness helps keep tooth profiles accurate under load, reducing premature deformation.

Designed for 48P Versatility

This 48P 25T pinion suits many common RC applications, letting modelers change gear ratios for different track types or driving styles without compromising mesh quality.

Does the pinion require any modification to fit common motor shafts?

Most users will not need to modify the pinion; simply match the bore and set screw style to your motor shaft. If necessary, minor reaming for a perfect fit is common practice.

How does tooth count affect performance?

A 25-tooth pinion changes the final ratio compared with larger or smaller pinions, affecting acceleration and top speed. Choose tooth count based on your chassis gearing goals.

Are there recommended checks after first installation?

After the first run, recheck mesh, set screw tightness and look for any abnormal wear. Small adjustments to pinion height can eliminate noise and uneven tooth loading.
