Upgrade Your Gearset with a Precision Pinion

The Arrowmax AM-348020 pinion is a 48P, 20-tooth unit machined from 7075 aluminium to provide accurate engagement and dependable operation. It is well suited for hobbyists tuning gearing or replacing worn pinions on electric models.

Durable Machining and Finish

Featuring a hard-anodized 7075 aluminium construction, this Arrowmax pinion balances toughness with low rotating mass. The precision tooth cutting helps reduce vibration and prolongs spur gear life when set up correctly.

Broad Compatibility for Tuning and Repairs

As a standard 48P pinion, the AM-348020 adapts to a broad range of electric RC cars and buggies, making it useful for quick ratio swaps during practice or race day adjustments.

Which checks ensure a correct install?

Check that the motor shaft diameter matches the pinion bore, tighten the set screw securely, and set a small mesh clearance before running to avoid tooth damage.

Will this suit high-rev brushless motors?

Yes, when fitted with correct mesh and alignment, the 7075 aluminium pinion works well with modern brushless setups; monitor wear if running very high power levels.

How often should I inspect the pinion?

Inspect for burrs or deformed teeth after heavy sessions and check the set screw regularly. Routine inspections help prevent spur damage and unexpected failures.

Are there simple upgrades to improve durability?

Consider switching to a steel pinion if you run very high torque, or ensure your spur gear is hardened. Regularly checking mesh and alignment also extends component life.
