Precision pinion for RC drivetrains

The Arrowmax AM-308020 pinion is built to help tune gearbox performance and reliability. Crafted from 7075 hard aluminium, the 0.8 module 20-tooth design delivers consistent tooth contact and reduced deformation under load.

Why 7075 hard aluminium matters

7075 alloy offers a high strength-to-weight ratio and superior abrasion resistance compared with common aluminium blends. That means the pinion keeps its tooth profile longer, reducing the need for premature replacement.

Where this pinion excels

This pinion suits enthusiasts refining gear ratios on racers and basher builds alike. The Arrowmax AM-308020 is a versatile option for durable, repeatable performance across a range of 1/10 scale drivetrains.

How do I check shaft fit for this pinion?

Measure your motor shaft diameter and compare it to the pinion bore; some setups require a grub screw or adapter for correct mounting.

Is a locker or threadlock needed on the grub screw?

Apply a light threadlocker on metal-to-metal grub screws if you want extra security, but avoid heavy compounds that make removal difficult.

Can I use this with brushless setups?

Yes, the 7075 material handles higher torque from brushless motors, but confirm gear ratio and motor pinion compatibility for your setup.

How do I clean and inspect the pinion?

Remove debris with a soft brush, wipe with isopropyl if needed, and check teeth for wear or burrs after hard impacts.
