MBX Centre Coupling Joint Upgrade for MUGEN - Arrowmax AM-MBX-E0229  [AM-MBX-E0229]

Centre coupling joint for MBX platforms

Arrowmax created the AM-MBX-E0229 centre cup joint as a service spare for MUGEN MBX drivetrains, using spring steel to stand up to repeated stress. The component joins central driveshaft elements and establishes a repeatable pivot that influences centre driveline behaviour and the car's on-track feel.

This part targets MBX-series configurations; verify the match with your chassis layout before you buy. Typical replacement involves pulling the centre shaft assembly, swapping the cup joint, and reinstalling the original fixings. Standard hex drivers are normally all that is required, and you should inspect mating surfaces and retainers for wear during installation.

As a wear-prone tuning item, the joint can change drivetrain smoothness and transient response. Use a conservative run-in and check for free play after fitting to preserve consistent centre torque transfer and to help prevent binding in more aggressive setups.

This Arrowmax centre cup joint serves as a direct replacement for MBX drivetrains and is suitable for routine maintenance and precise setup work on MBX-based RC models.
