@@SoCal_rnr clearly you don't work on trucks much. Outside body panels will not interchange for years. Tailgate might before 19 & the door would but the line curves are different so it would look getto. Interior panels would be the only thing if they weren't badged. The seat would bolt in bitut the designs are different so it would have to be all of them swapped.
First 3 minutes...GMC: hmm maybe we should have added a front locker on an off road truck when building a rock course we can't always climb without it.
They should be offering it with a Torsen style limited slip in the front. Combined with the current traction control system it would make that truck miles better in off road and snowy situations.
Until they change the design of their front diffs a locker is a death sentence off-road. It's been an aluminum case bolded together since they went to IFS in the late 80s. The pinion gear acts like a wedge and splits the diff. Can't even get a aftermarket locker for the 8.25" in the half tons and only like 1 is available for the 9.25" in the HD trucks. Lol sad sad
I was so excited to see this truck off road, and realized how terrible it is when the front axle refused to split power.. come on GMC, how is your most capable truck, WITH a rear locker, your most off road truck when the front differential wont split power 50/50 over obsticles?!?!?!
@@pulvermacher80 I have a 7.3L Powerstroke and a 6.0L Powerstroke that I bought used for both. Granted I bulletproofed the 6.0L Powerstroke, but they are both dead reliable.
@@richfarfugnuven6308 the problem now days is the younger generation tuning these trucks then running them hard then putting them back to stock and selling them. Then a new owner has all these expensive repairs.
@@pulvermacher80 right. Thats the issue. Not the engine itself. Most diesel engines arent fully broken in until about 100,000 miles or so. But like you said when these young hipsters buy these diesels and put crazy lifts and wide skinny tires on em and tune the engines then put it back to all stock is where the new buyer runs into issues.
Chevy/GMC needs a zr2 half ton (basically this with better approach and departure angles and diff locks) and a HD power wagon competitor with diff locks. I mean come on Chevy/GMC just do it. Why not?
Exactly! I’ve been saying this ever since the TB and AT4 was released... they are half-assed attempts at an “off road package”. They are merely appearance packages as far as I’m concerned. They aren’t that much more capable than any other Silverado and Sierra with a good set of tires.
They need to totally go through that ifs system. It hasn't really changed since they designed it in the 80s. The diff is terrible and can't survive with a locker in it. I'm not gonna even get started with the BS links. It's sad too because they could have really competent off-road machines but don't think it's worth their effort
My buddy had a 6.2 diesel in a 3/4 ton. Had 10,000 pounds behind it, took a big run at this .5 mile long hill, couldnt make it. Put it in 4 low range and it refused to even move under its own power.
Do RC ...broken into 14 shots of it partially climbing one carefully paced pile. And I think there were actually 4 broken shots of it going under logs...I’m not sure why anyone thought going under logs was part of a “capability course” lol Shows you what soy drinking, impossible burger eating men call “difficult” lol
I agree there 6.2L needs to be standard with the Duramax as an option on ALL trims. The 5.3L needs to be either the base engine or just dropped completely from the truck lineup.
@@nikko3853 here we go again and the 5.3 under power comments. Side by side the 5.0 and 5.3 are fractions of a second difference. I have driven both many times towing and there is NO noticeable difference. 35 more hp or so and 15 ft lb tq with the 5.0. however the 5.3 tw curve is flatter.
I hear them talk a lot about "Looks, Looks, Looks", yup GM with their 35 different Looks "Packages" and still ZERO performance upgrades on their 1500s. Let's face it they put a $35 lift block kit with Slightly upgraded OEM shocks and a badge kit and call it a few thousand dollars good. Also that line "Yeah we made a truck for those willing to pay for it to look rugged" smh
The lift costs 2k installed. There is a block in the back. But a longer and tuned strut body upfront. Longer CV shafts, diff spacers too The best part of the trail boss /AT4 is they offer a slightly better than a level lift, but with full factory warranty .
Terrence Jones you must be new to the aftermarket parts world. Nearly every major suspension company offers lifetime warranty on their products AND mileage warranty on the powertrain thrusting said products. There isn’t a 2” leveling kit out there that costs $2,000. Hows that kool-aid taste?
@@nikko3853 That's hilarious. For the record I've been in auto parts for 20 years. 10 of them in the aftermarket. I currently work for GM in auto parts. I know exactly what the lift kit costs. Because I can see the part numbers, and the break down of the lift kit/what comes in it. If you install an aftermarket lift in your truck. Your suspension , hub bearings parts of your OEM warranty is void. Move along junior.
@@nikko3853 Magnuson- Moss does not apply if you are alternating how the suspension functions. If you claim to be in the industry you know that even a simple spacer block changes your upper and lower ball joint angles. As well as tie rod end angles You reduce the lift span of those components in doing so. Show me a lift company that warranties failure of the OEM ball joints. I'll wait. A larger 4-6" lift with a new spindle can change wheel bearing loads, as well as offset wheels and larger tires. This is basic stuff. You should know better.
Had an '02 2500 Duramax and despite it only having 300hp/520 ft lbs, it just pulled hard. Loved that diesel. The 3.0L Diesel will be a great truck with 30 mpg hwy and all that torque down low - in a much lighter vehicle. The camera system the GM developed is just the best. Hope this engine is installed in the SUV's and maybe a hotter version for the Escalade, like Audi did for their Q7 (in Europe). Can't wait to try one out.
This shows super clearly why the G80 sucks. Get rid of it and add a manually engaging locker. Wearing out your tires to get the locker to lock (if it even does) is stupid.
@@joshpolzin3704 the g80 is garbage for off road the counter weight is to heavy to stay locked kicks out cause that's what its designed to do ......that's why I cut off half the counter weight that kicks in the locker then they will lock under a heavy right foot.
I agree on the need for a selectable or better locker. However I would also add that my work provided 2019 F250 with an E-Locker will frequently fail to disengage without stopping and hitting reverse and back to drive, and the truck has 20,000 miles on it. I only suggest that whatever is put into the truck should actually work properly.
So, i began to think when he was going up the rocks. When i was in the military some of the trucks had a CTIS built in that would air up and down the tires depending on the terrain. You would think jeep or any manufacturer would lead with that tech in off road vehicles
This truck is intriguing, but is ridiculously overpriced, by at least $10K+. I also am waiting for some automotive "journalist" to corner one of the engineers and ask them what they suggest a diesel 4WD driver should do when he/she gets a "DPF full, Drive To Clean" message when the vehicle is 10 miles back on some rock-crawling trail where the engine can't be run in a manner to allow a DPF regen. This is not a hypothetical situation--I've seen diesel pickups in exactly that difficult position. Ford at least offers and optional software program on their 6.7 Super Duty XL and XLT pickups that will allow a driver to initiate a stationary re-gen if the driver gets a "Full DPF" warning and can't, for whatever reason, drive the truck down the highway for 20 minutes to re-gen the DPF. By the way, slow speed-up/slow down rock-crawling is one of the driving regimens that will produce the most diesel particulates and fill the DPF most quickly. Why don't you TFL guys EVER report on this? I've been around diesels for about a half-century now. Why don't you hire me?--I'll ask those questions without hesitation.
rockymountainjazzfan the DPF is simply a filter. Sensors measure the amount of back pressure and determine when a regen is needed. It will attempt to do a regen until it’s able to do so and regardless of what the manual says it will do a regen it stop and go conditions - it just takes longer. There’s no need to force it to do a regen unless you just don’t like looking at the alert on the dashboard. Source: owner of a modern Chevy diesel. Don’t make a mountain out of a mole hill for arguments sake - you want drive like you described then get a Jeep.
GMC knows that most of the guys buying this truck would be performing a DPF and DEF delete within the 1st year so they would never encounter that issue with the regen
Oh my, a carbon fiber box... and people were complaining about the cost to repair the fords with their aluminum panels. I bet that box is astronomically expensive!!
If the camera views allow you to see "through" a trailer behind the truck, It would have been nice to have something similar to Land Rover and see "through" the hood and engine compartment with your virtual tires shown for direction of travel. Not a big difference but cooler.
I was at a dealer and there is no skids plates only on the engine and it to tin :( that’s all :( They need to put the interior from 2021 Yukon :) and electronic lockers to :(
Was that Cherokee Canadian? I thought only the liberty had a diesel 4cyl in the entire US jeep lineup. And wasn't the diesel VM unit originally a MB clone? I was looking for diesels years ago and really wanted a Cherokee diesel, but only found Canadian vehicles for sale
Outside of the front camera, i think my 13 FX4 F150 has pretty much every off road thing this truck has. The Ford has a selectable rear locker and doesn't need a 2 inch lift to clear the factory 32" tires. 33's Fit a stock F150.
@@artiaga1547I came from a gm family. I don't think we ever owned a Ford. My first one. I owned 3 GMC pickups prior to buying my Ford. I used to be a GMC guy but a man's wallet can only take so much of a beating before you try something else. This Ford hasn't been perfect but compared to the GM stuff I had, it's had a small fraction of the issues. Had it almost 7 years and it's not going anywhere anytime soon. Almost went back when the 16 Chevys came out because they were sexy... But damn the interiors suuuuuucked compared to my Ford. It felt like going to a midsize from my F150 and soooooo cheap feeling. Too bad, that was the best looking truck they've made in a decade plus. GM used to set the bar for design IMO but they've fallen off a cliff this century in that department.
The problem with Diesel engines is people want to immediately "Delete and Tune it" I understand why, I do. However I like cleaner air better. Ever get behind a diesel blowing all that black smoke on a nice day and you can't get around it? Yeah that's why they put all the emissions on it, those particulates are a known cause for Cancer. Might as well leave the emissions on it anyway. States are going (from what I am reading) to start enforcing these emissions as diesels become more popular. Dealerships are already getting to where they don't want to touch a deleted and tuned truck for fear of not being able to move the product. Looks like a great truck, good job Roman.
Enough with the lousy Rancho shocks. It's time to put some proper shocks on there instead of those bargain brand pieces of crap from a budget lift company.
87gunsnroses Rancho isn’t the problem. GM gives Rancho the specs and design for the shocks that Rancho must follow to the T. GM is far too conservative in bringing on performance products which is why the ZR2 is so unique with its proprietary shocks.
I would like to know why gm did not slap turbos on the 4.3L. Please ask this question tfl. They did back in the early 90's and had a performance machine that could keep up with the muscle cars of that era.
Explain how it's not a locking differential? Its certainly not an open diff and locks the wheels together once 100rpm wheel speed difference is met, below 20mph.
@@hogrod when rock climbing and you lose traction and then have to start spinning your other wheel to 20mph for the "locker" to engage a lot of things can happen you would definitely lose your forward momentum. Tfl has a few videos of it struggling. Where the actual rear diff lock didn't even sweat.
GM rep: Ok stop here, now shift into 4hi Roman: This truck has 4hi? How do you do that? GM rep: I've watched your channel, we know you love 4lo but 4hi is only one small turn of the dial, not the full turn Roman: Oh! That's what that is? Lol 😅
I'm starting to have a better understanding of what a rear-locker does and is for (the G80 for the GMC's) but I'd like it if TFL could do a video to better explain how the front locker works when the AT4 is in "auto".... specifically, is there a G80 under the front axle? if not, what's making the "auto" work for those two wheels? EDIT: Also, if you go into 4Hi or 4Lo, how does the G80 stay in continuous "locked" mode? I'd like to understand how this works too....
"The camera revolution has made off roading so much less stressful." Are you serious right now??? These trucks are designed for people who want to look cool but dont want to do cool things. Go to moab in the off-season and look what real cool trucks are, 80s Toyotas and 90s jeeps with very little electronic babysitters built in!
Brian Mattingly anything from Bilstein, Fox or Old Man Emu will be a good improvement. Within those brands there are everything from entry level (already better than anything rancho) to more committed off road builds. Personally I think the DSC fox shocks are the best of both worlds. Nice smooth adjustable city driving and a separate adjustable off road driving. But you’ll pay more of course.
Nic Restrepo I have a 15 Duramax , it doesn’t get off road a lot. Just around the farm I’ll never need the high dollar fox shocks but I would like to replace my ranchos soon they are getting rusty . Ive been looking at Bilsteins . Thank you for your time and answering my question!
In that case def look into Bilstein 5100 series. They’re the go to reliable performing shock. They’ll be softer around town but still have plenty of performance on washboard and dirt roads. Fox 2.0 would be the equivalent but at a higher price and they’ll ride a bit too firm around town...no need since your HD Silverado already rides a tad firmer than LT trucks. Oh... and they won’t rust, they might show some oxidation, all cosmetic, but nothing that will make the shock fail overtime.
Well curious to see a *0-60 & mpg run on the 3L Duramax* . I like it personally so far definitely the #AT4 package & so does everyone else in town its popular along with the Denali. They have Silverados running around but mostly LT, RST, Custom, TrailBoss & below not many High country, LTZs. Unlike the Gladiator which i have only seen 1 literally to date on the road & 1 other at a shop. 19 newgen Rams are kinda semi-rare see one here & there but quite a few 19 classics which is what i like as well.
Yup, a locker would pop that aluminum diff like a grape. It’s possible to make a real steel/Iron ifs (Tacoma/H3) but modern day GMC sells mall crawlers to the uninformed.
@@jamescalvert240 more reliable? lol sure they make more power and torque, but they are definitely not more reliable. They also are built to be disposable. 150,000 miles, maybe 200,000, then the junkyard. I prefer an engine built to last.
Couldn't agree with you more, having drove an ecodiesel for 3 years and saw first hand how it performed and the fuel economy improvement with the emissions removed, I had to wonder if the big 3 had shares in the DEF companies lol
The mud was just a puddle. If you had buried it so just the tops of the tires were showing then came to a stop before you crawled out I would have been impressed, a car could have made it through that puddle!
It would be nice to see a Torsen style front limited slip like the Raptor has. Even the Tremor is getting a limited slip in the front as it should. I also like that GM hasn't went to the huge screen display on the dash. The Dodge has that and it just looks stupid to me. If I'm not going to watch movies on it I only want the screen big enough to do the job and not look like an I-Pad got stuck to the center stack.
Kills me when they put a dirt bike in the back don't close the trail gate. I guess it's just to show size of bed but it's not good for tail gate straps over time. Especially if you do it with a much heavier bike.
Leave it to Roman to get stuck in a manufacturer's event. Out of the 4 clips I saw he's the only one. It was a gnarly obstacle but the others made it with the same truck. Maybe wet tires?
He asked "will it figure it out", at that price point, yes the GMC should have figured it out. I do believe Toyota's crawl control would've figured it out with open diffs to boot.
@@joshmclain2152 sure it would have, and then the engine would have blown because the sump wouldnt be pulling oil in at that angle. With all due respect, I love all these Toyota fanboys making assumptions. Meanwhile the ZR2 already put the Tacoma out to pasture. Full size trucks are not comparable to a Tacoma. A Tacoma is much lighter. Even despite that Im not sure it would have done any better. As stated by others here, Roman was the only person with an issue. I like Roman, but hes like my wife. He seems to have issues no one else has.
Man.. I’m mad at GMC. I had a bad experience with my GMC 2018 Canyon duramax. Seeing this makes it hard not to stay mad. That truck looks and sounds amazing
I had diesel exhaust problems. Radio problems. Power steering problems. Check engine light was on a lot. Derated warning symbol. I bought the truck on December 31, 2018. In March I had enough. The truck was at the dealership most of the time. It had to go
B TL the gas motor gas I think 350 lb-ft and it gets about the same miles per dollar of fuel. I think most diesel fans are actually turbo fans. They talk about torque - yeah, gas turbo has it also.
777jones - 350lb ft is impressive for the turbo 4 banger and any modern truck with a Diesel engine one has to weigh the time it takes to recoup the price premium on initial investment BUT 110lb ft is nothing to sneeze at as well as 20/23mpg vs 23/33mpg , at least 2000lbs (probably more like 2500lb) higher tow rating and more range with a full tank of gas
TK BRAYER That has been addressed already. DEF fill is now located next to fuel cap behind fuel door and tank is mounted above the frame rails. I agree though the previous DEF tank and fill location was straight up ignorant.
@@mgp-bct7723 the electronic locking rear differential is so smooth and quick that you really dont lose a whole lot of steam. However, a manually locking rear diff would have been nice, it is not necessary. Hear we can see the rear axle locks, but front passenger tire wedged against a rock, all three other tires were on smooth rock allowing the tires to spin.
@@mountainmanjim6366 if it was so smooth and quick why did it not engage. You're out of the middle of nowhere and going up something like that I don't want to have to put in Reverse to get over the top we should be able to engage that lock ourselves and leave it there.
Cool truck and all but the people I see driving these Trucks don’t even use them as trucks and keep them in their garages all day until they go to the grocery store.
I LOVE the matte gunmetal color grill and foglights. I have a 2019 Sierra SLT and wonder if I can order the new color grill and swap it out with the chrome that is on the 2019 SLT?
Thanks for the awesome off road, daily, work truck and Chevy/GMC content video, I love my 2010 Sierra Crew Cab SLT (I’ve had for 6+ years, 90 of 160k miles) and look forward to buying a NEW AT4 1500 or 2500 in a couple years but still not sure on which. I’m thinking Duramax 2500; but for as little as I tow my little show truck bagged S10, I’m still thinking 2500 at the moment. I’ll see what the 2021/2022 has and then I will know. I just hope Chevy/GMC keeps the 1500 Diesel for my options later on. Thanks TFL truck, love the videos. All you guys are awesome and I hope the more words I type help you out, lol. Thanks again. Love the Hummer H2, Land Rover, Toureg stuff and more, too. So many cool trucks and SUV’s all the time, I need a bigger garage and driveway. You guys are the best.
I’m sure it’s extremely expensive 😬 I won’t buy new again, I thought $60,000. Was a lot... it’s getting ridiculous! The truck is becoming more of a princess, they need an off road version, that’s not an off road version, it needs a locker for the front axle too, less traction control please, it got me stuck once because I forgot to turn it off.
HELLO GM YOU LISTENING . . . . . WE WANT FRONT AND REAR LOCKERS . . . . . ON ALL OFF ROAD FOCUSED MODELS. I'm fine with just a rear Locker on the regular 4x4s but on an off-road Focused truck like the AT4 you better put them on the front and the rear otherwise what's the point.
Best half ton GM in a long time, but they need to put in the effort they did with the zr2, higher clearance front bumper is a must. And they at least need something in the front, either a limited slip a locker or something similar to Toyota's ATRAC.
