2014 GMC Sierra 3500HD Regular Cab Photos, engines & full specs

GMC introduced the fourth generation of the Sierra pickup truck in December 2012, and the new vehicle came with a completely new exterior design, chassis, and drivetrains. Customers could get it with a two-door Regular Cab version, fit mostly for work.

While its Crew Cab sibling was a mix of everything, being able to work all day long and carry a family of five with a big trailer attached at the back during weekends, the Regular Cab was mainly a regular workhorse with a cabin where there was room just for maximum three occupants, seated abreast on one row.

Thanks to the new design, the 3500HD Crew Cab didn’t look like a regular workhorse anymore. Its front fascia showed a bold, commanding look on the road. The redesigned headlights were no longer split into two halves by a horizontal line as on its predecessor and featured corner-mounted turn signals. In addition, depending on the trim level and options, the massive grille, covered with a chicken-wire style mesh, was available with a chromed finish. Owners could order the pickup with a set of fog lamps mounted on the outer sides of the lower bumper and with a pair of towing hooks. From its profile, the Sierra retained one of its best-known design elements, the angular cuts for the wheel arches. Behind the two-door Regular Cab version of the Sierra 3500HD offered the option of either a bed or a flatbed for various applications. Moreover, GMC delivered the Sierra 3500HD as a chassis cab for additional aftermarket equipment. The automaker installed wider quarter panels for versions fitted with dual wheels at the back.

The base version of the Sierra 3500HD Regular Cab was offered with the Work Truck trim level, which featured a bench seat for three at the front, with a fold-down center armrest. When the middle seat was not needed, it was lowered to provide additional comfort and a pair of cup holders. The driver fronted an instrument cluster filled with two large dials for the speedometer and tachometer, plus four other smaller gauges for various information. In addition, GMC installed a TFT display for other information provided by the vehicle’s onboard computer. The gear lever for the Allison six-speed automatic gearbox was mounted on the steering column. Upper trim levels featured two individual seats, better upholstery, and even an infotainment unit with a touchscreen mounted on the upper section of the center stack.

GMC built the Sierra 3500HD on a sturdy ladder-frame chassis fitted with front independent suspension and an axle in the back. Depending on the engine and version, the pickup was available with either rear or all-wheel-drive systems, with a low-range gear for the transfer case. The 3500HD could also pull 19,000 lbs. (8,618 kg) trailer on the hitch or 23,200 lbs. (10,523 kg) on a fifth-wheel system.
