16T clutch pinion for MRX-5 tuning

Designed for use with the Mugen MRX-5 chassis, this 16-tooth pinion is made from 7075-T6 aluminium and finished with a hard coating to resist wear while keeping weight down. It is intended for the clutch/pinion stage on 1/8 scale competition and club cars.

Fitment notes: mount the pinion onto the clutch pinion shaft using your chassis service procedure, set mesh to the recommended clearance and check that the motor and spur turn freely before driving. Be cautious with clutch preload adjustments and perform engagement checks after any gear change to avoid excessive wear.

Tuning role: changing pinion sizes shifts final drive ratios and alters engine or motor response on clutch-driven setups; a 16T option provides a single tuning step useful for improving acceleration balance versus top speed on MRX-5 vehicles.

Is this pinion an original Mugen part?

No, this is an aftermarket Arrowmax component made to be compatible with the Mugen MRX-5 clutch and pinion assembly.

How do I verify correct mesh after fitting?

Set the pinion to the recommended clearance, rotate the drivetrain by hand to check for smooth contact, then run a low-speed check to confirm no binding or excessive noise.

Can this pinion be used with different spur sizes?

Yes. Changing the spur gear in combination with this 16T pinion adjusts the overall ratio, allowing tuning for acceleration or top speed depending on track needs.

Does the hard coat affect fitment?

The hard-coating improves surface wear but does not change the nominal dimensions; fitment follows the same steps as an uncoated aluminium pinion.

What maintenance is recommended?

Regularly inspect mesh, grub screw tightness and clutch condition. Replace the pinion if you notice significant tooth wear or damage to avoid harming the spur.
