In 2007, GMC's focus in the heavy-duty truck market was devoted to an all-new one-ton model. A replacement to the conventional 3500-level, the 2007 GMC Sierra 3500HD achieved new level of maximum towing and hauling capacity. A 353-horsepower, 6.0-liter V-8 gasoline provided standard momentum for the Sierra 3500HD while an optional Duramax turbocharged diesel delivered 660 pound-feet of torque. As well as boasting strong performance and a rigid truck backbone of a GMT900-based platform, the 2007 model year Sierra 3500HD also featured technological advantages such as a gasoline engine utilizing Active Fuel Management and standard four-wheel anti-lock disc brakes. For 2011, the GMC Sierra 3500HD received an extensive refresh that included a revised front suspension. Developing up to 765-pound-feet of torque, an all-new Duramax 6.6-liter turbocharged diesel engine allowed a maximum fifth-wheel towing capacity of 21,700 Pounds to be achieved with the one-ton truck. The 2011 model year was also the first time the Sierra 3500HD could be trimmed as a high-end Denali model. The GMC Sierra 3500HD was completely reworked for 2015 with greater emphasis on both brute power and technology.
