Precision clutch pinion for MRX-5 tuning

The Arrowmax AM-MRX5-H0759 1st Gear 18T is produced for compatibility with the Mugen MRX-5 chassis and is built from 7075-T6 aluminium with a hard-coated surface to resist wear. It functions as an upgrade or direct replacement in MRX-5 clutch and gear assemblies.

This gear transfers motor torque to the spur and the durable finish helps maintain reliable contact for accurate meshing. It fits the MRX-5 spur arrangement and supports consistent tuning changes when you alter tooth counts.

Available tooth counts include 16T, 17T, 18T, 19T, 20T and 21T so you can adjust the overall gear ratio without replacing the motor pinion. When swapping the 1st gear, confirm spline alignment and clutch interface on your MRX-5 to guarantee correct engagement and acceptable backlash.

Yes, Arrowmax AM-MRX5-H0759 is intended as a direct replacement for the MRX-5 1st gear when spline and clutch fitment match the stock assembly.
7075-T6 offers higher strength than common alloys and, with a hard coating, improves surface wear resistance which preserves mesh accuracy over time.
Keep a record of mesh and backlash before swapping counts, test one change at a time, and monitor motor temperature and clutch behaviour to find the best setting for the track.
