Fleece Performance TufShafts Axle Shafts

Fleece Performance TufShafts axle shafts are direct replacement upgrade shafts for any 2001-10 GM 2500-3500 with a 9.25 in. AAM front axle. They're designed to eliminate the stock passenger side split axle shaft that is prone to breaking under high torque situations, as well as the short drive side axle shaft that is prone to breaking under high torque situations. The TufShafts are made from high-strength HyTuf material for maximum strength and reliability. These heavy-duty load-bearing components transmit power from the transmission to the wheels. They are the link between the differential and the wheels, enabling your vehicle to move forward or backward. NOTE: TufShaft does not incorporate an axle disconnect, so the front driveshaft will spin when the vehicle is in motion; but with the front differential unlocked, the truck will turn and drive like normal.
