Here’s a bird’s-eye view of the front three-link suspension and drivetrain design. The 9.25-inch American Axle Manufacturing (AAM) straight axle sits under a pair of coil springs. A panhard bar provides lateral location of the axle and steering input comes from a traditional powered recirculating ball steering box. Exclusive to this segment of trucks is a front-axle disconnect system used to reduce parasitic loss and improve fuel efficiency up to 1 mpg. Front disc rotors are 14.17 inches in diameter and work with dual-piston calipers.
