Arrowmax AM-364051 7075 Hard Pinion 64P 51T  [AM-364051]

Reliable 7075 Pinion for RC Drivetrains

The Arrowmax AM-364051 pinion provides a strong, low-mass gear choice for model builders and racers. Machined from 7075 aluminium, the 64P 51T configuration maintains consistent tooth spacing for dependable meshing.

Why Choose 7075 Aluminium?

7075 aluminium combines high tensile properties with a light footprint, which helps resist deformation under load while not adding excessive rotating weight. That makes it a sensible material for pinions used in frequent running.

How It Affects Drive Quality

Precision gear cutting on the 51T pinion leads to improved contact patterns with the spur gear, reducing vibration and helping your motor apply power more evenly across different driving conditions.

Compatibility and Practical Setup

Before fitting, check that the motor shaft spline and bore match the pinion. Set mesh accurately and use the appropriate grub screw torque. A short test run followed by a recheck will ensure stable operation.
