Improve Drivetrain Consistency with Arrowmax AM-348045

The Arrowmax AM-348045 pinion is aimed at enthusiasts who want dependable mesh and clean power transfer. Crafted from 7075 aluminium, the 48-pitch, 45-tooth specification offers a precise fit with common 48P spurs.

Precision Machining for Smooth Operation

Careful machining of the tooth form helps reduce backlash and noise, while 7075 aluminium keeps the pinion light yet able to handle repeated runs without rapid wear.

Adaptable for Different Racing Styles

Whether tuning for quicker acceleration or higher top speed, the 48P 45T choice allows straightforward ratio swaps and works with a wide selection of spur sizes to suit your setup.

What checks should I make before fitting?

Confirm the motor shaft diameter and the pinion bore match, ensure the set screw seats on a machined flat if present, and verify clearance to nearby chassis parts.

Can I use this with composite spurs?

Yes, 48P aluminium pinions pair well with composite or steel spurs. Monitor wear patterns over time and avoid mixing heavily worn components.

How do I spot early wear on a pinion?

Look for hooked or chipped tooth tips, uneven contact across the tooth face, or metal shavings in the gearbox. Replace the pinion at the first sign of significant damage.

Is any break-in required?

A short run at moderate speed to seat the teeth is recommended, followed by a recheck of gear mesh and set screws before full-power use.
