MUGEN MRX5 Rear Axle Shaft (7075-T6) by Arrowmax AM-MRX5-H0277-Al  [AM-MRX5-H0277-Al]

Rear axle shaft for MRX5

This rear axle shaft is an RC-scale replacement part made for the MRX5 chassis, supplied under Arrowmax part number AM-MRX5-H0277-Al. The AM-MRX5-H0277-Al version specifies 7075-T6 aluminium as the material, offering a balance of reduced mass and dimensional strength compared with softer alloys.

On the model, these shafts act as the final link between the universal joints and the gearbox output, influencing drivetrain stiffness and rotational mass. They are supplied as a matched set so that both sides of the rear drivetrain use the same material and dimensions.

Installation is standard for MRX5-compatible rear axles: remove the wheel and hub, slide out the existing axle from the gearbox/drive cup, then fit the replacement shaft ensuring proper seating in the drive cups and bearings. After installation, verify free rotation and check for binding at full suspension travel before track use.

Choose this axle shaft when you want a consistent aluminium option for MRX5 rear drivetrains; pair with correct bearings and universal cups for best fitment and predictable handling response.
