Race-Ready 18T Pinion for Mugen MRX-5

The Arrowmax AM-MRX5-H0759 18T pinion is aimed at Mugen MRX-5 builders who want a robust, low-mass option. Made from 7075-T6 aluminium with a hard-wearing finish, the gear gives dependable tooth engagement and stands up well to routine use.

Tooth Count Options

Available in 16T through 21T sizes, this pinion range helps you dial gearing for different track types and driving approaches. Changing pinion size is a straightforward way to tune vehicle behaviour.

Will a 7075 pinion noticeably change handling?

The mass difference at the pinion is small, so handling changes are minimal. The main benefits are strength and wear resistance, which support consistent performance lap after lap.

Can I use this pinion with non Mugen gearboxes?

It may fit other gearboxes if the shaft size and spline match. Check dimensions before fitting, and be prepared to use appropriate adaptors or a different pinion if needed.

Best practice for setting gear mesh?

Use a paper or feeler gauge method to set a slight clearance, secure the pinion clamp or set screw evenly, then recheck after a short run. Proper mesh prevents premature wear and noise.
