This Arrowmax item is an RC-scale front/rear drive shaft supplied as a pair, intended for Mugen MBX series maintenance and setup work. The component uses spring steel to balance torsional response and fatigue resistance, serving as a direct replacement or upgrade within the MBX drive train.
Use this part where predictable shaft flex and consistent engagement are required, for example when adjusting driveline stiffness during on-track tuning or replacing worn drive components after frequent running. The part is presented as two pcs to cover one axle position set.
Choose this drive shaft when you need a like-for-like spring steel replacement for MBX driveline tuning, and check spline fit and bearing condition during installation to preserve drivetrain reliability.
