The Mack Clutch Cable Assembly is a genuine OEM air-assist control component designed for CXU, CXP, CHU, GU, and CTP model trucks. This complete assembly features an integrated pressure regulator and a high-tension steel cable housed within a reinforced, corrosion-resistant conduit. Unlike a basic loose cable, the Mack 20804977 is engineered as part of a specialized air-operated system that reduces pedal effort by approximately 20% while shortening travel for improved driver comfort. The unit includes pre-installed threaded rod ends and seals to provide a permanent, airtight connection between the cab controls and the transmission-mounted assist cylinder.
