Upgrade Drive Smoothness with Arrowmax AM-348045

The Arrowmax AM-348045 pinion provides a simple route to improved gear contact. Made from 7075 aluminium, the 48-pitch 45-tooth profile aims to keep power transfer smooth while standing up to routine track use.

Durable Construction, Accurate Teeth

7075 aluminium gives the pinion good fatigue resistance without excess bulk, and the accurate tooth cut reduces chatter and improves efficiency between motor and spur gear.

Swap Ratios Easily

Use the 48P 45T pinion to fine-tune your gear ratio for corners or straight-line speed, fitting a broad variety of spur sizes and setups without losing reliable engagement.

Do I need special tools to fit this pinion?

Basic tools like an allen key for set screws and a motor holder or pliers for shaft alignment are sufficient. A gear mesh gauge or a strip of paper helps set correct clearance.

Is 7075 aluminium better than steel here?

7075 aluminium is lighter and resists corrosion, offering good durability for most hobby use. Steel can be tougher but adds weight and may wear matching spur gears differently.

Will this affect motor temperature?

Changing pinion size alters load on the motor; a higher tooth count can slightly reduce motor RPM and heat for a given spur, but always monitor temps after gear changes.
