Machined 21T Second Gear for Precise Spur Engagement

Designed with the Mugen MRX-5 in mind, the Arrowmax AM-MRX5-H0762 21T second gear uses 7075-T6 aluminium to deliver a robust yet lightweight upgrade. The hard-coated surface reduces wear from repeated runs and helps maintain consistent gear contact over time.

Advantages of Choosing the Arrowmax 21T

Careful machining and a tight tolerance profile mean the gear meshes cleanly with common MRX-5 spur gears, cutting down on friction and noise. Racers can select from different tooth counts to fine-tune acceleration and top speed for each circuit layout.

Can I swap this into other Mugen MRX-5 variants?

Yes, the gear fits common MRX-5 variants that use the same second gear mounting. Verify tooth count and mesh for your specific spur gear.

Should I change motor gearing after fitting this part?

You may need to tweak pinion or spur tooth counts to achieve the desired final ratio. The Arrowmax 21T is intended to give predictable changes when tuning gearing.

Is the hard-coating necessary for hobby use?

The hard-coating improves surface wear resistance, especially useful for regular track use where metal-on-metal contact is frequent.

How do I maintain the gear to extend service life?

Keep the gear free of grit, check mesh regularly, and inspect for burrs. Light lubrication on mates can help reduce wear without attracting debris.
