Arrowmax AM-348019 48P 19T 7075 Hard Pinion Gear Track Ready Pinion  [AM-348019]

High-Strength 19T Pinion for 48P Drivetrains

Hobby drivers who demand consistent gear engagement will find the Arrowmax AM-348019 a solid option. Built from 7075 aluminum, this pinion resists wear while keeping inertia down for responsive acceleration.

Strength and Weight Trade Off

7075 aluminum provides robust mechanical properties that suit high-load situations. The material helps reduce deformation at the tooth root and maintains mesh integrity during extended runs.

Compatibility with 48 Pitch Systems

The 19-tooth specification is matched to 48 pitch spurs, allowing straightforward installation in many common motor and gearbox combinations. It is a practical swap when tuning final drive ratios.

Best Practices for Mounting

Ensure a correct gear mesh and secure the pinion to the motor shaft to avoid slippage. Inspect teeth and keep the area free of dust and grit, and recheck alignment after the initial break-in period.
