This JR-AS213 steel main centre drive shaft is an RC-scale replacement built for the Axial SCX10 II chassis. It serves as a simple, robust drivetrain link to transfer torque between the transmission and axle assemblies in slow-speed rock crawling and technical trail running.
Because the shaft is steel, expect altered drivetrain inertia and different wear characteristics compared with stock parts; factor this into lubrication choices and bearing inspection routines when you swap it in. During fitment check spline engagement, yoke seating, and ensure there is no binding across suspension travel.
Maintain the shaft by inspecting mating surfaces and universal joints regularly after hard use. Promptly address any visible wear to prevent secondary damage to bearings or adjacent drivetrain components.
