Even though it is pricey - it is about $6-8k cheaper than putting a diesel and leather in the Ram 1500 or Ford F-150. You might get a slightly cheaper trim at Chevy, but there is no comparison in price when you look at the complete package. Needless to say, my AT4 is on order...
Any updates?
Selective rear locker is ok for off roading if your willing to turn it off and on when making sharp turns so your not dragging your rear end but the automatic locking rear is better when your not expecting slipping in every day situations.
Agreed. Also better for most drivers who wouldn't know what a locking diff is and when to turn it on.
@@NukePooch1 Ford just started offering e lockers in 2012 these Ford guys just started to learn what a locker is lol
I hate to say it, but I kind of like the setup Toyota uses on their vehicles with locking diffs. My 4Runner has a selectable locking rear diff, but it also has traction control (ATRAC). If I get into a situation where a rear wheel starts slipping, it will apply the brakes to that wheel and send power to the other. I tried it a few times, it actually is effective. If that fails, then it's easy to hit the button and turn on the rear Locker.
The ATRAC also works on the front wheels, which is kind of like having a limited slip in the front.
Or on the first generation Jeep Rubicon, I believe it's axles were limited slip, and then you could lock them up as well. Best of both worlds there.
@@trailrunnah8886 ATRAC is a mountain goat! I have been more than impressed with how good it works off road.
@@JAMESWUERTELE haven't had the opportunity to take mine anywhere that I really needed it, but hopefully this year I'll get to utilize it more!
Were I looking for a new half-ton 4WD pickup (I'm not), the GMC AT4 with the diesel would be about #1 on my list. The two biggest downers: the ridiculously high price (true of all new pickups these days) and the stupid design belt-driven oil pump (the belt requiring a labor-intensive replacement at 150K miles). Instead of all the blather about electronic locking vs. limited slip differentials (I have lots of experience with both on my 4WD vehicles), here is the SOLUTION: install a Detroit Locker in the rear--it stays locked all the time except for turning corners. It's always there when you need it and is bulletproof (I have one that has given zero issues in 13 years in a 4WD). Then, install a Detroit Truetrac differential in the front axle. Another bulletproof design. Neither the Detroit Locker nor Torsen are outrageously expensive, and they both are more effective than the factory offerings. Problem solved.
Good comment, auto lockers.
Well said and I agree the prices of these new trucks these days are out of control. Even with all the technology the prices are out of hand. In my opinion to try and get something affordable the options are almost to basic.
Agreed and agreed. Here in Canada they’re going for 80 grand after taxes and fees. 80 grand for a half ton 🙈 I’m sorry that’s just nuts.
150000 miles is pretty good for a belt considering I've seen lots of regular gear drive pumps fail before then so 🤷 not a big deal to me
Even on NY's Day you guys are pumping out the quality content! Keep it up, guys, and here's to an awesome 2021!
I've put 10k on my AT4 since September. It's a great blend of on road comfort and off road capability. The Diesel is quiet and very responsive....and gets good economy especially when filling up at Costco for $2.10 per gallon. Love it. Does great in snow and slush as well...but I put Michelin LTX's on. Love them as well. Had Duratracs on my old All Terrain and didn't care for the dry road performance.
Super excited about this engine! Sad to see a hwy tire as the spare. I hope it's at least the same size tire. I hope GM comes out with a mid-to large offroad SUV (like the Bronco) and puts this engine in it!
Great video Andre.
I bought an identical twin to that truck. Every option even the same color.
I got 10k off sticker witness employee pricing and rebates. It’s super nice truck for the money.
Love this turbo diesel I6 . Best driving diesel I have ever owned. Very impressed with it.
I wonder if we're watching these snow videos for the purposes of, 1 - they're good content and informative and 2 - Andre choosing his next truck, lol.
Love me some TFL snowy videos
This gmc gets excellent traction in the cemeteries too. I’ve never gotten stuck driving over a fresh grave.
Handsome looking truck. Much better than the Silverado.
TB looks better than AT4
I think so too. I'm a ford guy so I don't keep up with GM products every year but I thought the new Silverado was uglier than sin. This GMC though is a very attractive looking vehicle. The RAM trucks look pretty good I think. The front of that Silverado though 🤢🤮.
@@TheMeanmarine13 all I have to say is my truck doesn’t need a 6 inch lift to fit 35’s like the GMC lol, I’m running a level kit and it’ll clear 35’s lol
I'm with you about a front locking axel and a selectable rear differential. I think we need to sue the manufacturers for false advertising saying they are 4 wheel drive and they are not. Yes I want a 10% form what ever Lawyer takes up this Class Action Suit. 😎
When I bought my AT4 I was convinced I wanted the 6.2. After adding a set of 34s, its noticeably slower which is to be expected. While it was in the tire shop I took my friends 3.0 Duramax for a spin. I quite like the power delivery of the diesel compared to the 6.2. In the next year or so, I’ll likely trade into the diesel. It’s power delivery is perfect for moving a heavy vehicle through traffic.
The 6.2 will have lower maintenance costs, and doesn't have after treatment and def to cause you issues.
I bought a diesel elevation..... I Don't think I can ever go back to a gasser...
Grass is always greener. Keep your truck. No emissions no fuel filters etc. just change gearing
Nice review of the AT4 Andre. Thanks for the video TFL.
Get the ZR2 if you want a fully capable GM vehicle and don’t want to break the bank. But if you like full size and have the money this AT4 is pretty cool.
I got a 2014 ZR2 and I love it....except for GM disabling my truck fob apps on my phone this year and deciding its now part of onstar for 20 bucks a month. Assholes.
As to the AT4 that's allot of money for a front lift, smaller chin spoiler and painting the tow hooks red instead of black. Yeah get the ZR2. You can remove the spoiler yourself if you want and the front lift is a simple enough upgrade.
I love my 2021 AT4
2:30 Although the Goodyear Duratrac tires are not winter tires, they do have the three-peak mountain snowflake symbol. According to TireRack.com that symbol means it is "severe snow service" rated. From TireRack.com:
"A three-peak mountain snowflake (3PMSF) symbol branded on a tire's sidewall indicates the tire meets required performance criteria in snow testing to be considered severe snow service-rated. Originally used as a designation for winter tires, the 3PMSF symbol is now featured on some all-season and all-terrain tires with snow performance that meets the testing criteria."
Yup TFL is against everything that's not Ford. They have alot of biased opinions.
I thought thats what they were referring to when they said no snowflake. That's strange. I got Coopers with the 3 peak rating and they're fantastic. Decent offroad and pretty good in the snow.
Most do, but it seems some sizes aren't rated
It is weird. Goodyear only lists one size of Duratrac that is not winter rated (three peak and not this size ) yet the duratracs on the gm trucks do not have that symbol on them. Same tire though......
@@vernhardie9500 it's not the same, OEM get to choose compounds, gm chose longer life over the peak certification.
Since when was a half inch of snow considered a snowstorm in Colorado?
Or anywhere?
In southeast texas it is
That’s what I thought
You don't have the full amount during the storm. Notice it is still snowing.
I don't get the hate for the g80. You don't have to stop to engage it and if you adjust your driving habits to how it works its fine. Its never left me stranded in my 2014 and I've seen guys get stuck because they never engaged their locker and then had to stop in the middle of some pit to engage it.
Love my g80
I just bought this truck!
Funny how the DuraTracs are on the floor, but the spare isn't the same (shown by camera underneath tail). M & S still no flake on a high end 4x4 truck.
Pretty sure mine has a flake on the tire, different size duratrac
The DuraTracs on my ZR2 have the three peak rating, and the spare is a matching DuraTrac too. Surprised they didn’t do the same on this more expensive truck.
I love how you guys keep testing new vehicles let it be any weather. Looking forward to see how well mach e performs in snow comparing with Tesla
That same truck in 23’ is like 76k…. Kind of nuts when you think about it. Hopefully dealers bring back incentives soon
Nice review Andre, very relaxed look at the very nice looking truck. You seem to do really good reviews by yourself with the bike men as cameramen. Good job on the camera Kase. Stay safe.
Wow 😮 i love the GMC
Happy New Year Thanks for doing your program. It’s the best Michigan
Love that diesel sound
Regarding the video's comments around 9 min for putting bigger tires on-good luck going much bigger on the AT4-even with its 'factory 2 in lift'! I have a 2017 All Terrain, put 2.5 inch Fox front coil overs in and Fox rear shocks and upgraded the tires to 34 in Falken Wildpeaks, and get front rubbing when I crank down hard to the drivers side. I could probably take out the wheel well insert on that side, but I just ignore it-its not leaving marks on the insert or the tire. With the even more square wheel wells on the AT4, you'd probably have to do some cutting/trimming for bigger tires or get a bigger lift I guess-but I still think the shape of the wheel wells is problematic to size up to a bigger tire. Would love to upgrade to a diesel, but got a heck of a deal on mine as an end of the year factory close out. Would go with a diesel SLT though and put on the suspension and wheels/tires I want-think the cost would come out about the same as the AT4 w/ a upgrades better than spacers/Rancho shocks/decent tires on factory wheels.
Good thing it comes with all those cameras so you can see in real time where you can't go without lockers.
🙂👍
😅
My 2010 GMC AT has front locker. I believe , all 4 wheels turn in 4 wheel drive, but not in Auto. No crawl. I take of sync. In mud. Works much better
There was no front locker available from Gm
polsok44 thanks arne
The 4x transfer case has a clutch that engages the other front wheel. Technically not a locker but it works well when used in Auto mode driving in the rain and snow.
The look of this truck is really growing on me, I like it better than the Silverado. I just wish the GM would make a truck with radiused wheel wells. Tires are round, yet GM loves their square or trapezoidal shaped wheel wells. A rounded off wheel well would probably allow for a 35 on this truck, and there's no reason one shouldn't be able to run a tire that big on a truck this big.
Love your guys videos and watching them, you guys always pack in the info👍👌 Just as a suggestion for what the vehicles are capable of. You should start in 2 wheel drive traction control on off, then switch to 4 high traction control on off, then switch to 4 low track control on off, and diff lock if that's an option on and off. I know it would make the videos quite a bit longer but it would be very informational, and cool to see the capability of each vehicle in each mode 😉🙃🙂
When’s tfl just gonna buy one of these?
Beautiful truck and great review! I'm amazed at all the camera views!
Love you guys!!! Wish you could test a deleted titan xd 😆
Thank you so much for this. I had thought of this truck as a possibility. But now, not sure, Like to find a vehicle for hunting, fishing camping. I'm just not sure which one
Those Rancho never get old! Lol!
The 1500 looks way better than the HDs but it still look like it has buckteeth. That said, I really like the diesel option.
Hey guys 38M live in Ca. and we don't get snow, focus!!!
Andre, will this be your replacement to the H2?
I have wrangler duratracs and they got the snowflake rating
Love the video Andre
Nice silver n black for me 👍
Pretty sure duratracs have the snow ❄
Some do not like some ko2 do not
Lets have that Landrover Defender on here already but be sure to take a tow motor for when it breaks down lol.
Duramax makes the best diesel engine in North America
"duramax" isnt a company that makes anything.
problem with these diesels offered by GM is they can only be purchased with high end models and it cannot be purchased with an 8ft bed. this makes zero sense. The trade contractor, owner operator are the customers that can take full advantage of these types of diesels, not high end trucks buyers which for the most part use these trucks as a commuter vehicle and for 5% of it's use pull a trailer on the odd weekend. Shame.
GM was going to offer it in a reg cab, but accounting said it would be a $6K upcharge, due to new computers etc. that's why RC does not have 10 speed.
General question about American trucks and offroading. Has anyone damaged or sheared off the overly exposed rear shocks mounting? They hang awfully low and I fear it getting damaged if accidentally hitting a rock. Not sure how it impacts the function, but I would think it would be better if mounted closer to the wheel. Thoughts?
Did I hear him correctly.? Duratracks no snowflake and mountain symbol? They are up here in Canada. Weird.
GM requested a longer lasting compound, that why the factory tires dont.
@@cordellroberson532 That makes sense, thanks for the info!
You should air down the tire pressure ....
Barely broke a sweat on that trail
I'm just curious why did you cut the traction control off?.. I thought it was supposed to be helpful..
Happy New Years!!
It won’t go up by itself? If it has the hill start brake assist package it won’t , it brakes like it should
BFGoodrich mud & snow tires. Hot Hot Hot Michigan
Can't beat a BFG.
Great truck
Wishing you and the team a Happy, Safe, Healthy New Year. And thank you for a testosterone infused, experiential, informed landing experience, and for providing part of my personal, routine landing choice experience. Thank you.
Correction Andre. Check the sidewall because Wrangler DuraTrac tires are Mountain/Snowflake approved.
Thank you but I will take the Chavey LT Traill Boss with the Duramax Diesel engine!
gm should make a limited edition at4 with a front solid axle
Did you try turning the know to off road see what the difference it makes. If not do a video on it thx
Anyone remember the old days when it took skill to navigate difficult terrain off road. You had to know the dimensions of your truck. Now you don’t even need a spotter. Next you will have LIDAR and you won’t even have to drive. The truck will just navigate the rocks for you.
Does you not taking air out of the tires when you're going off-road for better offroad performance?
I am guessing this video was shot same time as Kase’s 2nd gen ram diesel off-road video posted on TFL classics .
I am wondering which truck made it the furthest up the iron clads trail?
Is the rear diff leaking? It looks like there’s diff lubricant on the exterior.
Michael Hasenstab It's a General Motors vehicle. Need the question be asked?
There is no fluid on the rear diff, there are a couple ribs it looks like must be for pleasure.
For the everyday person I don’t need all that tech. I like having my lt trail boss with not all the gadgets
Do a the same test with the Ford F-250 tremor
Hmmm Andre sounds like you want the 4wd set up from, dare I say it, the Defender. Now let see how much bashing this comment gets. BTW Happy New Year to you Andre and the whole TFL crew!
Wait, did I just suddenly hit that part of UA-cam that I can only like once.... dang it...........
So trail boss or at4? Which truck is a better buy
My durotracs have the snowflake rating
These guys need to get serious about testing snow capabilities. Maybe they should watch a couple Arctic Truck videos. 😂 Ford (or even just snow) fans should check out their modified F150 on 44s.
Are sure they are not 3 peak rated?
Someone in the comments said they were.
I love the new gm trucks but there way to much money and I'm very sure they will not last 500.000 miles with paying for them 3 times over none of the new stuff will it's a shame it's come to all this electronic crap on them it's just not going to work long term but great job showing us
That’s why I got a Chevy ZR2. Has front and rear lockers and you can get them in the high 30k range.
Theres a reason my newst truck is 24yo
Amen!!
Just watchin for research hey.
@@Malc664 good for you!!
You would think that after over 100 years of building vehicle's the issues would be figured out and they would be reliable..
While they got the old problems figured out over the years now there's new ones and the prices are doubled!!
Hey guys, I have a GMC AT4 and will be visiting CO in mid Jan, I am looking for an easy to intermediate trail you would recommend I could go have some fun exploring. Thanks for any advice.
Many of the trails are closed in winter, you can end up with feet of snow in a day on the trail so to keep people from being trapped they close them.
Andre does the heater work well? The price isn't good, $50k I would pay for that.
Why didnt you get the winter rated duratracs with the studs? please!
Can this Diesel engine get tuning. If yes than from the factory or third party thanks for helping
15 different camera views! LMFAO Are we off-roading or staring at the screens?
Both lol.
Wish it was with the 6.2 instead of the diesel...
What are you going to buy to replace Frank the Hummer, Andre? And will we see a video about it?😁
Never mentioned the tires size?
275/65r18
@@cnovak1994 Just 32 inch tires same as stock on my Tundra. Thanks.
The Silverado doesn’t come in the 3.0L Duramax. Only the AT4.
GMC LOVE BRASIL
Do duratrac no longer have the snowflake? They used to have it
There are different models now I think. Just like the coopers I use.
Funny situation with the Duratrac on the AT4 and Trailboss. They don't have the snow flake rating on the tire. But if I used my GM parts catalog and look up the tire PN, as soon as I plug that # into the tire manufacturer website, it says they are snowflake rated.
My guess, Goodyear charges for the rating. GM didn't want to pay for it.
Besides overlanding use , why the hell would anyone want a full size offroad rig ? Makes zero sense and wont be able to navigate most trails anyways ..
In Colorado maybe, Where I live its not an issue as everyone drives drives trucks or big suvs mostly. Honestly I think trails get formed by whats the most common offroader where you live. Its nothing but farmers here so trucks.
@@loganholmberg2295 I live in the Rocky Mountain region, and trail clearance is a big issue for full-size rigs. Probably half the 4WD trails in the region can not be safely negotiated with a full size 4WD (though people often try it with sometimes unpleasant results). That said, people here often need full-size 4WD's to carry heavy loads into backcountry work sites, etc. That's me, so I have both--a smaller 4WD for hardcore 4-wheeling and a full-size 4WD pickup for the heavy load hauling. That's actually pretty common around where I live. Sometimes a single vehicle just can't meet someone's needs.
@@rockymountainjazzfan1822 👍
@@rockymountainjazzfan1822 yeah up there I'd probably have a 4x4 truck and a side by side for the trails. My dad likes to do that in the forest here cause he likes to hunt bogey terrain and getting a full size truck unstuck is a sever pain in the ass compared to a side by side. Shit you can get those so kitted out nowadays I think I'd rather have those than a jeep.
There are people that would use this offroad truck for offroad work. If you think about where your food comes from farmers need offroad capable trucks that can also haul stuff for fencing, etc. There are others also that will need a full size offroad truck like cattle haulers, fishermen that pull a bigger boat need it if they fish away from the crowds. There is many uses for an offroad vehicle other than playing on a trail.
my driveway is more of a challenge up by Craig,
Less hp and torque than a EcoBoost, and they still cant make round wheelwells.
Who needs a locker for Walmart wheeling.....🤪
Does the hat come with truck?!
What did we see in this video?
If you buy an “off-road” truck why would you care about the wheels and tires if you are going to change them anyway?
For more news, views, and baby Flintstone chews.
No shit it doesn't wanna go by itself... thats what the skinny pedal on the far right is for...

G80 sucks. Also sucks can't get the diesel in the custom LT 1500 silverado
Never had an issue with mine offroad. As long as you adjust your driver habits for it it'll see you through.
Get a HD they make the real diesel in every trim!
A GM dealer told me that GM does not put the 3.0L diesel option in the Chevy Custom or LT Trail Boss because it would pirate half-ton diesel sales from the GMC division. There are still a number of GMC dealers that are not Chevy/GMC multiple line dealers, and GM wanted to protect their single-line GMC dealers from internal competition from Chevrolet dealers.
@@dtlusk24 True. Also, one can also usually spec a "Plain-Jane" HD pickup with off-road options that will actually cost less in actual "out-the-door" sales price (not MSRP) than many of the "fancy" off-road half-ton pickups like the 1500 AT4. In hard use, the HDs will usually last much longer, too.
@@dtlusk24 no you cannot get the diesel in the custom trim. Only 6.6 gas
TFL is not gonna say it, but GM could do so much better, especially for that price. GM buyers are loyal to he brand but GM is not as loyal to their customers.
You should have compared to other diesels
Youd think that if a truck as expensive as this would use something as LAME as a G80, youd think that at least they'd put one up front.
They don't expect it to be driven offroad all the time, most trucks stay on pavement almost all the time. Even these will be onroad more and if you are a serious offroader you will do a front and rear locker like a detroit.
@@badgerpa9 I understand that but if they're trying to market this as an off roader from the factory, they should offer it with some more capabilities from the factory.
