Arrowmax AM-RX8-348518 18T Hard-Coated Aluminium Pinion for XRAY RX8  [AM-RX8-348518]

Race-ready 18T pinion for XRAY RX8

The Arrowmax AM-RX8-348518 18T pinion is turned from 7075-T6 aluminium to reduce rotating weight while keeping tooth strength high. The hard-coated finish improves wear resistance so the gear keeps a clean mesh under racing loads.

Balanced lightness and toughness

7075-T6 aluminium gives a low inertia feel without sacrificing durability, which helps acceleration response. The hard coating limits surface wear and lengthens usable life between replacements.

Simple fit and tuning range

Engineered to mesh with XRAY RX8 spur gears, the pinion is offered across a typical tuning spread of 16T to 21T. That scope lets you tune driveability and top speed to match track layout and surface grip.
