Narrow year range (drag arrows to filter):
For 2014, the gasoline-powered GMC Sierra gets a new standard 4.10 rear axle. The previous 3.73 axle remains optional. Also new are an available spray-in bedliner and the expansion of the bi-fuel gas/CNG 6.0-liter V8 to the 2500 model line.
For 2013, extended-cab 2500 HD models equipped with the standard 6.0-liter V8 can be had with a new bi-fuel system that accommodates both gasoline and compressed natural gas (CNG). Two new exterior colors (Sonoma Red Metallic and Heritage Blue Metallic) round out the changes.
The 2012 GMC Sierra HD sees a few improvements for this model year. A new hard-drive navigation radio is offered, while Work Truck models gain cruise control and lockable spare tire. Denali trims gain as standard equipment heated and cooling front seats, a heated steering wheel, a rearview camera and, on 3500 dually models, 17-inch polished wheels.
The 2011 GMC Sierra HD's Duramax turbo diesel's power, torque, maximum conventional and fifth-wheel tow and payload ratings are best in class. Its fifth-wheel tow capability is 21,700 pounds, it can tow up to a 17,000-pound conventional load with its factory-installed hitch, and the Duramax is fully B20 biodiesel compatible.
Technical upgrades include the addition of Bluetooth hands-free communication technology to OnStar 8.0, as well as Destination Downloads for vehicles equipped with DVD navigation. Extended and Crew Cab trims offers a rear backup camera, while a stability enhancement system is made standard on the 2500 HD with single rear wheels.
When you need a full-size truck to haul heavy objects, the muscle provided by the 2015 GMC Sierra HD will be more than sufficient. Like the 2015 Chevrolet Silverado 2500 and 3500 HD, the Sierra HD is General Motors' other answer the Ford F-Series and Ram HD trucks. Both the Sierra 2500 and 3500 HD offer you the choice of a 6.0-liter V8 gasoline engine or a 6.6-liter Duramax turbodiesel V8, as well as rear-wheel-drive and 4-wheel-drive configurations. The choices go on from different cab configurations and bed lengths to trim levels. Even though it's not the best heavy-duty truck in its class, the Sierra HD offers plenty of muscle to get the job done.View GMC Sierra 2500 HD Regular Cab vehicles for sale near you.

"Now that i outright OWN the 2015 GMC Sierra 2500HD Crew Cab (6.0L V8 Vortec) SLT 4x4 (Z71 Off-Road Suspension Pkg) i can relay some of my initial driving experience w/it as an owner instead of just test-driver. It gets better gas mileage than my old Jeep Cherokee V-6 2WD (both city/hwy mileage), so i can't kick. To all y'all that want better MPG's: you might best stick w/the ½ ton GMC Sierras w/Eco-Tec or Duramax engines (or whichever mfgr. brand you favor). As far as the "on-the-column" gear shifter (automatic transmission) - I didn't find mine to be "jerky" at all. My old vehicle had the on-the-console automatic shifter, & 1 before that had gear shift on the steering column. Same function but shifting on-column is NOT something you ram or slam into gear, you "slow & easy" position the shifter into proper gear otherwise "you overshot the mark" & need to re-position to correct. I checked the on-the column automatic transmission gear shift a bunch before I full-on bought mine- on account i read a review posted here that made mention of "jerky" shifting probs. Mine works just fine & IF it DIDN'T, I WOULD'T buy it. If it came up faultering after I bought it, oh boy!..you can bet I'd have it looked at, right QUICK, while under warranty. Mine shifts proper & to my liking. The truck itself is a champ! On the subject of off-road, well, I'm NOT "ditch jumpin" w/it but the 4WD (hi & lo) is just plain fine, IMO, for general all-terrain purposes. Haven't hauled "heavy" with it yet. I'm real pleased i opted to have the 20" FORGED polished aluminum GMC wheels instead of 18" alum. clad wheels! The factory spray-on bedliner is better than I expected. The paint around the very bottom of the chassis could've been finished better (I found one tiny 1/4 globule that formed a stray droplet along the very edge near the underside of the wheelhouse - slight "orange peel" where GM applies a protective undercoat beneath exterior paint color alongside to the lower left of where the assist steps normally are situate . This undercoating near bottom edge of chassis is resident on most all 4x4 Sierras I inspected while shopping, and was/is limited to the area near the rear wheel housings, drips or were visible more in some than others (i found that dealers are commonly blaming that on automated mechanical paint application). More on this in immediate follow-up."

"Truck is stylish. Very quiet. Very little road noise. Pleasure to drive during the day. Has lots of nice features. HOWEVER, the headlights are absolutely terrible. Far too dim. Extremely hard to see on back roads. Wish I would a known this prior to purchase. Previous models have great LIGHTS. No excuse for this other other than poor engineering."

"Very quiet ride. Nice looking. Steps in rear bumper great idea. Sharp looking interior. Great gas mileage. 19.6 mpg on 2800 mile trip carrying 900 lbs cargo. Engineers overlooked some small but important things. Projector headlights are terrible, no peripheral lighting on hi beams, interior dome lighting is bad, outside temp reading doesn't update frequently enough, speakers in front doors stick out too far and get kicked when exiting, piping on leather seats is very irritating when exiting or entering frequently, no provision to turn off auto door locks, infotainment screen is too bright for night driving and cannot be dimmed independently from the dash lighting, interior is super quiet but I still have to listen to the key fob rattle against the steering column on uneven roads, side mirrors are too small and can't see rear wheels with them, steering wheel mounted controls are no longer at your fingertips but are now smaller and mounted higher up and can't be felt with gloves on. Less vision out windshield compared to previous model. I use this truck for work and a lot of times at night with entry and exit at least 50 times a day. This truck is not as convenient or comfortable as the previous model."
