Slimmer axle shafts built for sharper MRX5 handling

For drivers tuning a Mugen MRX5, Arrowmax presents rear axle shafts made from 7075-T6 aluminium to trim rotating mass without sacrificing strength. These components are aimed at improving the car's feel on the circuit.

Why 7075-T6 is used here

The 7075-T6 grade offers a high tensile strength with relatively low weight, helping the axle resist deformation while keeping the car nimble. That makes it a popular choice for performance hardware.

Engineered to match MRX5 geometry

Produced with accurate dimensions to match MRX5 driveline interfaces, the shafts are intended to reduce play and support smooth power transfer during aggressive driving.

A straightforward upgrade for club racing

Swapping to aluminium rear shafts reduces unsprung mass and can sharpen throttle response and turn-in. It is a simple modification for hobbyists looking to refine balance and predictability.

Can I use these with my existing dogbones and cups?

They are designed for the MRX5 driveline standard, so confirm your dogbone length and cup interface match the MRX5 specification before fitting.

Are aluminium shafts more fragile than steel?

7075-T6 is strong for aluminium but has different failure modes than steel. It handles race loads well but inspect regularly for wear or impact damage.

Do these need any break-in?

No special break-in is required, but check fitment and run a few gentle laps to confirm there is no unusual noise or binding after installation.
