2005-2018 Cummins G56 Manual Transmission 3rd Gear Mainshaft (ZMG56-11)

Your mainshaft is responsible for transferring power from your engine to the gears within the gearbox, then to the wheels. Like the majority of transmission internal components, if you have difficulty changing gears or notice grinding, clunking, or unusual noises, this could be a sign of a failing mainshaft. USA Standard Gear manufactures some of the best OEM replacement transmission and differential components for your truck, making building or maintenance a breeze.
