Precision Pinion for the MTX-5

The Arrowmax 18T pinion crafted from 7075 aluminium delivers a reliable tooth profile and smooth engagement for the Mugen MTX-5. It is suited to drivers who want a durable replacement that keeps drivetrain feel consistent during race runs.

Strength and weight benefits

7075 aluminium is valued for combining high tensile strength with low weight, helping the pinion resist deformation while limiting rotating mass to preserve throttle responsiveness.

Installation and setup advice

This pinion is produced to match MTX-5 gearing geometry for straightforward fitment. Set the gear mesh carefully and recheck after a few runs to ensure optimal contact and longevity.

Will the Arrowmax pinion fit without shims?

Most MTX-5 builds will accept the pinion with standard spacing, but some setups may need a thin shim to achieve ideal mesh. Always check under load.

Should I change pinion size for different tracks?

Yes, changing pinion tooth count alters acceleration and top speed. Use 18T as a baseline and adjust up or down to suit short technical tracks or high speed layouts.

Is 7075 aluminium prone to chipping?

7075 aluminium is strong but can show wear over time. Inspect teeth regularly for nicks and replace the pinion if damage appears to prevent spur gear wear.

Can I run this pinion dry or should I lubricate?

A light application of suitable gear grease on the spur mesh can reduce wear, but avoid heavy coatings that attract dirt and debris.
