For the past two decades or so, the Sierra 3500 has been GMC's most capable full-size pickup. Thanks to its stiffened suspension, sturdy frame, powerful engine choices and available dual-rear-wheel axle, the heavy-duty Sierra is a go-to choice for those with big towing and hauling needs.

For that same period of time, however, the truck has suffered from lackluster interior design and below-par interior materials. Happily, interior quality improved considerably with the GMC Sierra 3500HD's 2007 redesign. Mechanically, the beefy Sierra is pretty much identical to the Chevy Silverado 3500HD, with differentiation coming mainly through exterior styling and minor interior and feature alterations.

Current GMC Sierra 3500HD
The GMC Sierra 3500HD is available in regular, extended or crew cab designs. Rear-wheel or four-wheel drive is offered, as is a dual-rear-wheel axle. The extended cab and crew cab body styles are offered in four trim levels: Work Truck, SLE, SLT and top-of-the-line Denali. The regular cabin can only be had in Work Truck and SLE trims. Moving up through the ranks obviously adds more style and features, culminating in the Denali.

Standard on all Sierra 3500HD pickups is a 6.0-liter V8 that makes 360 horsepower and 380 pound-feet of torque, paired to a six-speed automatic transmission. The burly Duramax 6.6-liter turbodiesel V8 that puts out 397 hp and 765 lb-ft of torque is optional. Its standard Allison six-speed automatic is well-suited to towing and hauling large loads.

The Sierra 3500HD is arguably the most competent, refined and easy-to-drive heavy-duty pickup on the road. Although multigenerational brand loyalty may dictate which heavy-duty pickup you take home, sticking with (or switching to) the Sierra 3500HD would no doubt be a solid decision if you want a full-size heavy-duty truck.

The present-generation GMC Sierra 3500HD debuted for the 2007 model year. Two years later the truck received Bluetooth and an updated version of OnStar with turn-by-turn navigation. For 2010 the standard 6.0-liter V8 saw output increased to 360 hp and 380 lb-ft of torque (previously 353 hp and 373 lb-ft). The following year saw a number of significant changes such as all-new frame and suspension components (for greater towing capacity and a smoother ride), a more potent turbodiesel engine cranking out 397 hp and 765 lb-ft  (previously 365 hp and 660 lb-ft) and the debut of the ultra-plush Denali trim level.

Previous to the current truck, there were two past generations of the Sierra 3500. They were still known as the 3500 but lacked the "HD" moniker.
