Product Introduction
The 3894110411 / 6544110511 Flange Fork is an important drivetrain connection component used in Mercedes-Benz SK, NG, MK, Actros MP1 and Beiben NG80 trucks. Installed on the propeller shaft assembly, it connects with the universal joint and flange structure to transmit driving torque from the gearbox to the axle while allowing flexible movement caused by suspension changes.
Manufactured according to OEM specifications, this flange fork features high-strength alloy steel construction, accurate mounting dimensions, and excellent resistance to heavy loads and vibration. It is widely used for propeller shaft repair, drivetrain maintenance, and replacement applications for commercial trucks.
