Arrowmax AM-RX8-348518 18T Aluminum Pinion for XRAY RX8  [AM-RX8-348518]

High precision pinion for XRAY RX8

The Arrowmax AM-RX8-348518 18T pinion is machined from high-grade 7075-T6 aluminum to balance strength with low weight. Its hard-coated surface boosts wear resistance so the gear can withstand the demands of frequent racing and practice sessions.

Lightweight yet resilient

Using 7075-T6 aluminum keeps rotating mass down while delivering strong resistance to deformation and abrasion. The hard coating adds another layer of protection, helping maintain accurate tooth profiles and consistent gear mesh under load.

Fitment and tuning flexibility

Made to mesh cleanly with XRAY RX8 spur gears, this 18T option sits in a range of tooth counts from 16T to 21T for straightforward tuning of acceleration versus top speed. Swap tooth counts to dial in gearing for different track surfaces and race formats.
