The ability to pull and haul the heaviest loads with the available Allison® 10-speed transmission while delivering a smooth, comfortable ride: This heavy-duty truck dream is a reality in Sierra Heavy Duty. GMC engineers achieved capability and comfort by using an optimized body structure, isolating cab mounts as well as components.

Knowledge is powerful. It’s also the foundation of your confident trailering experience. Sierra Heavy Duty offers you the tools to help stay in control of your truck and trailer with the available ProGrade Trailering System. This suite of intelligent trailering technologies streamlines the hitching and trailering process to help give you more control and confidence.

Sierra Heavy Duty offers a number of available active safety and driver-assistance technologies that help in driving and trailering situations. Many of these innovations use a combination of cameras, short- and long-range radars and ultrasonic sensors to help you avoid potential collisions and make you and your companions feel safe, secure and confident.

Sierra Heavy Duty offers beds that are long and wide to handle your biggest loads with the available 7,442 lb. max payload. The bed height makes for comfortable lift-in loading and is optimized for gooseneck/fifth-wheel trailer clearance. To help protect the floor, a spray-on bedliner is standard on Denali and AT4 and available on other trims. The available factory-installed Gooseneck/Fifth-Wheel Prep Package includes a frame-mounted hitch platform ready to accept a fifth-wheel hitch or gooseneck ball, a bed-mounted trailer wiring connector and stamped bed holes with removable caps installed. And don't forget the world's first, six-function Multipro™ Tailgate and industry-first, available transparent trailer view.
