2012 GMC Sierra 3500HD Overview (See Available Styles)

For out of this world towing and payload capacities, the 2012 GMC Sierra 3500 heavy-duty pickup is an excellent choice to handle all of your rugged needs.

There are only a few changes for 2012, including the addition of heated and ventilated seats, a USB port, satellite radio, and a hard-drive-based navigation system. Trailer-sway control and hill start assist are now part of the stability control system. The 2012 Sierra 3500HD is available in four trims: WT, SLE, SLT, and the upscale Denali. The GMC Sierra 3500HD shares the same platform/powertrain options as the Chevrolet Silverado 3500HD, but is slightly more luxurious.

Choose between several cab configurations, including regular, extended, and crew-cabs, in addition to several different bed lengths that vary from 5-feet, 9-inches to 8 feet. Powering the 2012 GMC Sierra 3500HD is a 322-horsepower, 6.0-liter V-8. If you need more oomph, a 397-horsepower, 6.6-liter turbo diesel V-8 that generates a whopping 765 pounds-feet of torque for prime hauling and towing capability is also available. This engine is mated to a six-speed automatic Allison 1000 transmission with manual shift control. Choose between a traditional floor-mounted transfer case and an Autotrac knob-controlled electric transfer case that engages when wheel slippage is detected. An available smart exhaust brake provides greater control on downward grades and reduced brake-pad wear

Due to its strengthened cargo box, revised shocks and cushier rear springs, towing maxes out at 23,000 with a fifth wheel trailer, while the Extended and Crew Cabs can tow up to 18,000 pounds. The Regular Cab with a gas engine offers a maximum payload capacity of 7,215 pounds.

In terms of the interior, the 2012 Sierra 3500HD features an available power-sliding rear window, rear-seat entertainment system, leather-wrapped heated steering wheel, backup camera, 10-way power-adjustable driver’s seat, Bose audio system, power moonroof, and Wi-Fi system for mobile internet access.

Safety is a priority for the 2012 Sierra 3500HD with four-wheel antilock brakes, rear parking sensors, front-seat side-impact airbags, curtain airbags, traction control, rollover mitigation technology, seat belt pretensioners, and OnStar, which automatically alerts authorities in the case of an accident.

There is no job too big for the monstrous 2012 GMC Sierra 3500 heavy-duty pickup.
