There’s really no better setting to reveal a new pickup truck than Texas. Specifically, the Texas State Fair. And that’s just what GMC did with revealing the new, highly revised 2015 GMC Sierra 2500 and 3500 HD trucks — vehicles that we refer to as “brutes in suits”. With these new power tools comes reworked sheetmetal that provides improved aerodynamics, while a slew of user-friendly features make work easier, and a quieter, more thought-out cabin with more technology and higher-quality materials gives us gains in overall refinement. But for you number buffs, here’s the important stuff:
The 2015 GMC Sierra 3500 HD delivers a best-in-class payload rating of 7,374 pounds – and the highest conventional tow rating of 19,600 pounds (with a factory-installed, frame-mounted box-tube hitch), while the maximum fifth-wheel rating comes at 23,200 pounds. These are all improvements over the outgoing ratings of 21,700 pounds from the fifth wheel, 17,000 pounds of hitch towing, and 6,635 pounds of max payload.
It’s important to note that the updated line of 2015 GMC HD trucks still utilize the GMT900 frame and not the K2xx frame that the 2014 Sierra 1500 introduced — much like how the frames of the outgoing models kept with the GMT800 frame until the 2011 model year. We await a chassis refresh of sorts in the coming years. The 2015 GMC HD trucks also keep with the same 6.0L V8 and the proven 6.6L Duramax diesel and Allison Transmission powertrains. Though because this is the case, GMC can continue to offer a bi-fuel option that pairs the gas engine with a compressed natural gas system, just as with the outgoing HD model.
The 2015 Sierra HD models will be available with 6’6″ and 8’ box lengths that are said to be stronger, more durable, easier to use and offer greater cargo flexibility with features like the integrated CornerStep rear bumper, a trickle-down from the all-new 2014 Sierra 1500. The Double Cab body style also replaces the less practical extended cab variant. Also integrated into the new HD Sierra trucks is the new interior layout from the 2014 Sierra 1500, which means it’s more intuitive than before, with the GMC IntelliLink infotainment system front and center, and the row of toggle-switches that control features like Lane Departure Warning and Rear Park Assist.
The 2015 Sierra HD line will also offer the Z71 off-road suspension package on SLE and SLT models, which adds 35mm deflective disk twin-tube shock absorbers, off-road jounce bumpers, 33mm front stabilizer bar and a skid plate package. The Denali HD model also comes back, for those who desire glamour to go with their grit.

Living in the high chaparral cattle country of Central New Mexico – these new HD pickups are not only the vehicle of choice here, but are an inspiration in how much work can be accomplished. A 2015 GMC HD Denali 4X4 please!
Very disappointing no upgrades for the Duramax
WAGER PERFORMANCE ,how much torque do you want?
Someone Help me out here………..Since 2015 1s still about 15 moths away….Why is these Truck so Outdated before they even go into Production……I mean Beautiful Exterior/ Interior, but No New Frame and Engines that are (to Keep it Clean) so OOOOLLLDDD Scol vs. the Competition??? C’mon, I just praised how the New GM is Bringing it on All Fronts and you do this to me…..For Shame!!!! 🙁 🙁 🙁 I hope you got something Really Crazy Killer for us in store with Powertrian/Frame Really Really Soon.
I have to agree with you Dmax in that regard. Neither did they boost the HP on the 6.0 ! Why isn’t the 6.2 available ?
T-Mac.
Supposly the 6.2 isn’t ready yet from what I have heard. Because of being the 6.0 is a Bi fuel engine now. Where the 6.2 isn’t yet
No sure I understand the frame issue …. what was wrong with the current one? Even when GM went to hyrdoformed frames I never met anyone who cared as long as it held up to the demands of the job.
The frame complaint is just ridiculous the current or future frame has no problem pulling or hauling what it needs to
The engine is something I wonder what people really expect, how much hp/tq does a street truck need to pull 20k plus pounds?
These trucks have really strong frames, that’s not the issue. The issue is that you can see that frame sagging underneath the truck, on top of that, some genius decide to bolt a DEF tank on the side which sticks out like sore thumb!
I really like the way these trucks perform, but it also needs to look right! I’m not really satisfied with Silverado look, why go back couple of decades with that front end styling?? I was happy when they stopped with that crossbar all the way across, now they brought it back?? And splitting headlights again?? Why not move on and design it more modern?? Also I’d like to swap those torsion bars with coils, and have solid axle as an option.
I was wondering how long it would take for the solid axe crap to start! There’s is nothing wrong with GM frame hanging lower and that box you refer to my be a I sore to you but that’s on you and if you don’t have a strong enough back bone to drive a truck not pretty enough to make your friends happy speaks of your lack of character!
I think these trucks are outstanding in current form and I have every reason to believe that the next ones will be even better!
We need 801 ft/lbs from the Duramax to beat Ford!!!
This truck will pull what 90% of people are pulling. Will it pull the 30,000lb backhoe like a Ram? No. But I’ve pulled 28,000 lbs with a light duty tractor trailer with a single rear axle and had all I could do to control that weight when a car ran an intersection and I had to do an emergency braking. At some point, Government safety regulations are going to require these 30,000 lb 3500 series one tons to have dual rear axles to provide more tire contact with the ground to control these weights.
When one ton trucks are rated for 25,000 – 30,000 lbs, I’d be very concerned using them with that weight not because they can’t pull that weight, but because they can’t control that weight in certain emergency situations.
How about a 6.9L DMAX with 900 to 1000 Ft/lbs
@dpach
I agree Not to mention about having to have a CDL to drive it
Just so ya know in California, Ohio and few other states if you pull a trailer MORE THAN 19,000 lbs,
the state troopers on duty at the speed taps over the mountain passes or interstate exchanges
WILL PULL YOU OVER to make sure you have a Commercial Drivers License OR the Class B non-commercial license which applies to
gross vehicle weight plus trailer combos
greater than 21,000 lbs.
They ALWAYS go for the 3500/F350/3500HD guys pulling 5th wheelers because the larger 5ths
end up being around 21,000 lbs. So it’s $473 on the first try, $620 on the second and $1200 for
the 3rd NO CDL/Class B ticket.
You should get one anyways since a good CDL course will TEACH YOU how to pull the
basic and extended trailers SAFELY using the single rear-axle 1-tons.
It’s a BASIC safety issue because of only the SINGLE-axle towing capabilities of modern 1-tons
Yes very much so. Being I live in Ohio thats why I brought it up. Which isn’t a problem for me because I do Have my Class “A” Just people need to Watch what they are doing to STAY LEGAL
