XRAY RX8 19T Pinion Gear - Arrowmax AM-RX8-348519  [AM-RX8-348519]

Dedicated Pinion for the RX8 Chassis

This Arrowmax AM-RX8-348519 pinion is produced as a replacement component for the XRAY RX8, intended to serve as a direct-fit motor pinion within the clutch and gearbox layout of the car.

Manufactured in 7075-T6 aluminium and finished with a hard coating, the tooth geometry is matched to XRAY spur gears for dependable engagement. Arrowmax supplies this design in 16T, 17T, 18T, 19T, 20T and 21T so you can alter the ratio by swapping pinion sizes while keeping the same spur.

Fitting notes: confirm correct mesh and axial alignment before operating, employ the appropriate shims or a pinion spacer for the RX8 motor mount, and tighten the pinion set screw to the recommended torque. Small adjustments to mesh and backlash will affect wear and drivetrain noise, so inspect after a short run.

Tuning guidance: reducing pinion teeth increases acceleration at the expense of top speed, while adding teeth raises potential top speed. Make incremental moves when testing and check both pinion and spur for wear to ensure reliable performance.
