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

Aftermarket centre cup for MBX drivetrains

The Arrowmax AM-MBX-E0229 centre cup joint is an aftermarket RC spare built for MUGEN MBX drivetrains, made from spring steel to resist repeated loading. It serves as the central link between driveshaft elements, creating a consistent pivot that influences centre driveline behaviour and the vehicle's overall feel.

Fitment is intended for MBX-series layouts; always verify the part against your chassis diagram before fitting. Installation generally entails removing the centre shaft assembly, replacing the cup joint, and reassembling with the existing hardware. No specialist tools are needed beyond typical hex drivers, but take the opportunity to inspect mating surfaces and retainers for wear during the job.

Viewed as a consumable tuning component, this joint can affect drivetrain smoothness and transient response. Perform a modest break-in and check for unwanted play after installation to maintain reliable centre torque transfer and avoid binding on tighter setups.

As a direct-replacement part for MBX layouts, the Arrowmax centre cup joint is suitable for routine maintenance and fine tuning of driveline behaviour on MBX-based RC vehicles.
