High Precision 2nd Gear Housing for Mugen MRX5

Fit the Arrowmax AM-MRX5-H0289 to your Mugen MRX5 for a finely machined 2nd gear housing produced from 7075-T6 aluminium. The lightweight alloy increases structural stiffness around the transmission, helping maintain consistent gear alignment at speed.

Strength That Holds Up on Track

The design focuses on resisting repeated race stresses. 7075-T6 aluminium delivers a stiff, fatigue-resistant housing that helps protect internal gears and bearings during prolonged use.

Why Experienced Builders Choose Arrowmax

Arrowmax parts combine tight tolerances with race-minded design. This housing is a straightforward way to refine drivetrain performance without significant weight penalty, making it popular among hobbyists who tune setups for grip and balance.

Can I use stock bearings with this housing?

Yes, standard MRX5 bearing sizes are used. Check fit tolerances and press bearings squarely into the housing for best results.

Does it change gearbox maintenance?

Maintenance is similar to stock; however, inspect mating surfaces and hardware regularly as the stiffer housing can transfer more load to other drivetrain parts.

Is painting or anodising recommended?

Anodising offers corrosion protection and a neat finish. If you paint, avoid overspray in bearing seats and mating surfaces.

Does it affect gear mesh settings?

The housing maintains stock geometry, but always recheck gear mesh after installation since machining tolerances can differ slightly from OEM parts.
