Precision Pinion for Better Gear Engagement

The Arrowmax AM-348020 pinion is a precision 48P 20-tooth component made from 7075 aluminium for consistent performance. Its machined profile helps maintain clean mesh and reduces the chance of uneven wear during spirited running.

7075 Aluminium for Strength and Weight Balance

This Arrowmax pinion uses hard-anodized 7075 aluminium to combine strength with low mass, making it suitable for racers who value responsive acceleration without unnecessary rotating weight. The accurate machining improves life span against softer materials.

Suitable for Many RC Chassis Types

Designed with standard 48-pitch gearing in mind, the AM-348020 fits a broad array of electric RC cars and buggies. It works well as a replacement or a ratio change part when testing different setups on track or dirt.

Will this mesh with my existing spur marked 48P?

If your spur is 48P then tooth geometry should match. Double-check the motor shaft diameter and set screws to ensure the pinion mounts securely.

Is hard-anodized aluminium better than plated steel?

Hard-anodized 7075 aluminium balances durability and reduced mass, but steel still offers higher wear resistance for very high torque or nitro conversions.

How should I set gear mesh with this pinion?

Use a single sheet of paper to set a small clearance between pinion and spur, then tighten the pinion while holding mesh. Recheck after a short run to confirm nothing has shifted.

What tooth count changes handle better traction?

Lower tooth counts typically increase acceleration while higher counts favour top speed. Try swapping one or two teeth to find the balance that suits your surface and driving style.
