MRX5 Rear Drive Axle Pair 7075-T6 - AM-MRX5-H0277-Al Arrowmax for MUGEN  [AM-MRX5-H0277-Al]

Rear axle shafts for MRX5 drivetrains

This rear axle shaft set is an RC-scale replacement intended for the MRX5 chassis and is supplied under Arrowmax code AM-MRX5-H0277-Al. The AM-MRX5-H0277-Al specification denotes 7075-T6 aluminium construction, chosen to cut rotating mass while retaining greater strength versus softer alloys.

Functionally, the shafts transfer torque from the gearbox output to the universals and play a significant role in drivetrain stiffness and rotational mass. They arrive as a matched pair so both rear sides share identical dimensions and material characteristics for balanced performance.

Installation uses the standard MRX5 rear axle routine: remove wheel and hub, extract the old axle from the drive cup, then slide in the replacement shaft ensuring correct seating in the drive cups and bearings. After assembly, check free rotation and move the suspension to full travel to confirm there is no binding before track running.

Use this matched aluminium axle pair when you want predictable rear drivetrain feel on MRX5 cars; pairing with fresh bearings and proper universal cups gives the best results.
