MRX5 Rear Axle Shaft 7075-T6 Aluminium - AM-MRX5-H0277-Al by Arrowmax for MUGEN  [AM-MRX5-H0277-Al]

MRX5 rear axle replacement

This axle shaft is an RC-scale replacement designed for MRX5 setups and is supplied under Arrowmax part number AM-MRX5-H0277-Al. The AM-MRX5-H0277-Al option uses 7075-T6 aluminium, which lowers rotating mass while keeping greater dimensional strength compared with softer alloys.

On the car, these shafts connect the universal joints to the gearbox outputs and directly affect drivetrain stiffness and rotational inertia. They are supplied as a matched set so both sides of the rear drivetrain use identical material and geometry for consistent behaviour.

Fitment follows the typical MRX5 rear axle procedure: remove the wheel and hub, slide out the existing shaft from the gearbox drive cup, then install the replacement shaft ensuring it seats correctly in the drive cups and bearings. After installation, confirm free rotation and check for any binding through full suspension travel before track use.

Choose this aluminium shaft when you want uniform rear drivetrain behaviour on MRX5 cars; use correct bearings and universal cups to ensure reliable fitment and predictable handling response.
