This JR-AS213 steel main centre drive shaft is an RC-scale replacement made for use with the Axial SCX10 II chassis. It is a direct drivetrain component intended to transfer torque between the transmission and axles for slow-speed technical trail driving and scale rock crawling.
Pay attention to fit during installation: confirm spline and yoke engagement and check for binding or endplay through suspension travel. The steel construction alters rotational inertia and wear behavior compared with common stock materials, so plan lubrication and bearing checks when you fit the part.
Use the shaft to correct play or substitute a worn centre drive element, and confirm clearance with suspension links and skid plates while articulating. Regular inspection after demanding runs will help spot wear at mating surfaces and universal joints.
