2011 GMC Sierra 3500HD Specs

May 1st, 2011 by By auto # GMC

The 2011 GMC sierra 3500HD is available in three body styles (regular, extended cab and crew) and a single or double rear axle. There are over sixty different combinations of truck available with these options. All trucks have a bed available long. The bulk of these trucks is equipped with steel wheels of 16 inches. Other exterior features found on various cabins includes a locking rear differential, tow package truck, fog lights, a rear sliding window, sunroof, rear parking sensors, electrically folding mirrors and extending camper electric folding mirror, greater stability and suspension package.

The 2500 and 3500 come with a 6.0-liter V8 engine standard, though a 6.6-liter turbo-diesel V8 is available. All Sierras come with a heavy-duty 6-speed automatic transmission. The 2500 and 3500 can be had as either a regular, extended or crew cab, with a standard or long bed, and with either a 2- or 4-wheel drivetrain. Dual rear wheels are available on some models. There are four trim levels, Work Truck, SLE, SLT and Denali.

The standard engine is a 6.0L V8 engine that is capable of 360 horsepower and 380 pound-feet of torque. A 6.6L turbo-diesel engine capable of 397 horsepower and 765 pound-feet of torque is also available. A new fully-boxed chassis has been introduced for 2011, which GM says is 125 times stronger than the unit it replaces and allows for a smoother ride as well as a much greater towing capacity. When equipped with the diesel engine, the trucks are now capable of towing up to 20,000 lbs.

In addition to the redesigned frame, new stronger front and rear suspension systems have also been added, yielding a 25% increase in strength on 4×4 models. Now rated at 6,000 pounds, all 4×4 front suspension systems can easily support a snow plow when properly equipped. Rear leaf springs have also been updated, with the 2500 utilizing 2-stage leaf systems and the 3500 making use of 3-stage springs.

Some standard features cross all Sierra lines, such as driver and passenger air bags, 4-wheel disc brakes with anti-lock brakes and tire pressure monitoring. GM’s OnStar system is standard on the SLE trim and better. It includes crash response, roadside assistance and remote door unlock services. There are two suspension packages available for the 2500: the Z85 handling and trailering suspension and the Z71 off-road package, which adds high-performance shocks and a bigger stabilizer bar.

The Sierra Denali brings the Sierra HD pickup’s towing/hauling capabilities in a luxury and style-oriented package. Available in both 2500 and 3500 trim and both 2-wheel and 4-wheel drive–but only as a crew cab. The Denali comes with heavy-duty trailering gear, an electronic shift-on-the-fly transfer case on 4-wheel drive models, special wheels, body-color panels and molding and chrome trim, fog lights, power, heated mirrors, a high-performance Bose audio system and leather power-adjustable seats.
