Introduction to the Project Carbon® AS68RC Input Shaft & K1 Drum Assembly:
One of the most documented problems in the AS68RC transmission, especially in Dodge and Sterling trucks, is input shaft failure. In fact, nearly half of AS68RC transmissions we receive here as cores have a broken input shaft. When the input shaft fails, it destroys the pump and torque converter, a several thousand dollar failure to even just repair.
As a standard practice in all Next Gen Drivetrain AS68RC transmissions, our forged steel Project Carbon® AS68RC Input Shaft & K1 Drum Assembly is used. This product features an updated babbitt bushing as well as a forged steel construction enabling it to support the audacity of these powerful and heavily used vehicles. If your AS68RC transmission does not feature our Project Carbon® Forged Steel AS68RC Input Shaft & K1 Drum Assembly, it's simply not ready to put in work!
