MBX Centre Cup Joint for MUGEN - Arrowmax AM-MBX-E0229  [AM-MBX-E0229]

Centre cup joint tailored to MBX layouts

The Arrowmax AM-MBX-E0229 centre cup joint is a purpose-made RC spare for MUGEN MBX drivetrains, produced from spring steel to resist fatigue under repeated load. It links the central driveshaft components, providing a controlled pivot that affects centre driveline behaviour and vehicle feel on track.

Designed for MBX-series arrangements, confirm fitment against your chassis diagram before fitting. Removal of the centre shaft assembly, replacement of the cup joint, and reassembly with existing fasteners is the usual process. No specialised equipment is needed, though inspect mating parts for signs of wear when you service the assembly.

During tuning this item is a consumable that impacts drivetrain smoothness and transient performance. Follow a modest break-in routine and recheck for play after installation to ensure steady centre torque transfer and to limit binding in tighter setups.

As a direct-replacement centre cup for MBX chassis, this Arrowmax component is suited to regular maintenance and precise driveline tuning on MBX-based cars.
