Fine Tune Your Mugen MRX-5 with the Arrowmax 17T Pinion

Swap in the Arrowmax AM-MRX5-H0758 17T clutch pinion gear on your Mugen MRX-5 to improve drivetrain efficiency and part longevity. Made from 7075-T6 aluminum, this lightweight pinion keeps rotating mass low while offering the strength needed for sustained track use.

CNC Finish and Durable Hard Coat

The Arrowmax 17T pinion is finished with a hard-coated surface to resist wear and maintain a consistent mesh with the MRX-5 spur gear. Reduced friction means smoother acceleration and fewer surprises during race runs.

Multiple Tooth Counts for Setup Tuning

Arrowmax supplies this pinion in a range of tooth counts so you can tune gear ratios for more torque or higher top speed depending on course layout. Swapping pinions is a straightforward way to adapt a Mugen MRX-5 setup between tracks.

What is the best way to check pinion to spur mesh?

Fit the Arrowmax pinion to the Mugen MRX-5 motor, install the spur, then use a single sheet of paper or feeler method to achieve a snug but not tight mesh. Spin the drivetrain by hand and inspect for smooth engagement.

How should I maintain the 7075-T6 pinion for longevity?

Keep the pinion free of grit, check teeth for burrs after running, and replace it if you see deformation. Regular inspection and clean mounting hardware will extend service life on the Mugen MRX-5.
