High Strength 18T Pinion for Mugen MRX-5

The Arrowmax AM-MRX5-H0759 18T pinion delivers a sturdy, low-weight option for Mugen MRX-5 cars. Manufactured from 7075-T6 aluminium and finished with a hard surface treatment, this pinion resists wear while maintaining the lightness that helps drivetrain responsiveness. It is intended to mesh cleanly with compatible spur gears.

Available Tooth Counts

Arrowmax offers pinions from 16T up to 21T so you can alter gear ratios to match circuit demands or personal setup preferences. Selecting the right tooth count is a simple way to adjust acceleration versus top speed balance.

Is the 18T intended only for the MRX-5?

The design is targeted at the Mugen MRX-5. While it can be fitted to other cars if shaft and spline are compatible, many models will need different mounting arrangements or a different pinion size.

Does the hard finish affect break-in or run-in?

The hard surface treatment does not require a special break-in. Still, set correct mesh and check for any interference during the first runs to ensure smooth operation.

What parts pair well with this pinion for upgrades?

Pair this pinion with a quality spur gear and secure clutch hardware to get the most from the drivetrain. Keeping mating components in good condition helps extend overall longevity.
