AM-RX8-348521 Arrowmax 21T Pinion Gear for XRAY RX8 Performance  [AM-RX8-348521]

Track-ready Arrowmax 21T pinion for XRAY RX8

The Arrowmax AM-RX8-348521 21T pinion is produced for XRAY RX8 cars using 7075-T6 aluminium to reduce rotating mass without sacrificing durability. The hard-coated finish gives extra abrasion resistance for frequent practice or race days.

Precision cut teeth for smooth drivetrain operation

Manufacturing tolerances aim to provide an exact match with common spur gears, resulting in quieter running and improved efficiency. A choice of 16T through 21T tooth counts allows gearing tweaks for different track demands.

Materials that support quicker response

Choosing 7075-T6 aluminium lowers inertia on the motor shaft and helps the car respond faster to throttle inputs while resisting deformation during heavy acceleration.
