But it did do it! Once. 🤪

Tom Smith — And I’d like to see you try! LOL! Chevy’s do not have a viable 4x4 system intended for serious use, no locking differentials, no fancy faux simulated 4x4 drive, just a badge on the side that says 4x4. Subaru while not perfect, has a respectable system. The funny thing here is that you believe what you say and WANT to try! Hilarious! And before you go getting all defensive, why not realize that neither of these vehicles are intended to go off-road! They are just meant to be a little safer or better to drive on roads during messy situations. They are what they are! Like yours, great! But just know to take your HEAVIER, non locking-diff’s Chevy up this sandy hill is pure insanity. LOL!

Sammy Duran — No, Chevy has no vehicles with factory lockers, YOU must add them and it voids your warranty.

Sammy Duran — Perhaps, so? A rear locker gives you rear wheel drive without a locking center diff. With a center locking diff or limited slip you have a great 3 wheel drive car without locking front diffs. I don’t have a stick up my bum, I’ve been stuck and towed a lot of people out of sticky situations. It’s called experience.

Sammy Duran — What did it cost you to add those?

Sammy Duran I’ve looked at and considered buying a few Chevy’s, Dodge’s and Fords and never found a stock unit you describe. Ever.

Sammy Duran — I’ve towed many vehicles out of tough spots. Owners see 4x4 on the side and go off-roading, not realizing what’s needed or their vehicles capabilities and shortcomings. I am 60 years old, so... not a little boy. No Chevy, Dodge or Ford I’ve ever seen has had FACTORY locking diffs all around, which is why people get stuck. I will do some research and see if there are any facts to what you say.

Sammy Duran — O.K. Done. No locking diffs front center or rear it does have a “Autotrac® active 2-speed transfer case” though! LOL! Low gears are good! LOL!

Sammy Duran — The Tahoe Z71 says nothing at all of locking diffs.

Sammy Duran Gawd I hate homework...

Sammy Duran Chevrolet.com has zero matches for G80

Sammy Duran — Looking at Colorado, Tahoe and Suburban Z71’s, no mention of any locking diffs, just autotrac and 2 speed transfer cases. Are ya sure?

@rauland — You do know there are 3 diff’s right? Front, center and rear. If you have all 4 wheels in mud and just a rear locking diff... wait for it... ALL POWER WOULD GO TO ONE OF YOUR FRONT WHEELS. Why? Because with an open diff, all power goes to the wheel with the LEAST resistance. So the wheel that looses traction first, as in spins, gets all the power. I have winched a few dozen dolts in Chevy pickups out of the mud because they, like you, had trucks with 4x4 printed on the sides. Doubt me, go play in the mud. Don’t get me wrong, locking rear diff’s HELP, on roads in bad weather, especially if you are towing.

@rauland — Well, you’re right, I did say no locking diff’s. My bad. There’s only 2 vehicles sold in the USA w lockers all around (to the best of my knowledge), Jeep Rubicon and Mercedes G-wagons. All others have some sort of lesser/cheaper setups. Even the highly regarded Toyota Off Road Pro versions use a (cheaper/not better) computer controlled braking system to fake 4x4. They work great in most mild situations, but if you get them stuck in muck or sand, they will give up the fight. Meaning the computer tries a few too many times, gets confused and just pukes. You’ll hear people commenting here on YouTube to tow truck operators “Don’t know what’s wrong, everything seemed O.K., but now it’s like no power is going to the wheels.” That’s the system saying it ‘got so confused, I’m sick!’ Restarting the car sometimes works, turning off traction control seems to resolve the issue too. You can buy locking diff’s for a lot of vehicles aftermarket, but only two come stock. This might help, Most RWD cars use open differentials, meaning power goes to the wheel with the least resistance. Get one wheel on ice, and you’re stuck. FWD cars ditto, but some just feed one front wheel all the time, the other wheel is essentially a trailer wheel that steers. The next step up are limited slip diff’s which diverts power to the wheel w the most resistance. The best use locking diff’s, and trust me, old school is better. Front and rear differentials direct power to the front or rear wheels, center diff’s split the power between the front and rear diff’s. In AWD’s it’s usually a 60/40 (60% rear/40% front) split. Better ones have a locking center diff which sends power to the front and rear diff’s equally. AWD means power can be or is always going to all 4 wheels, but they are almost always allow plenty of slippage as they are driven on pavement. Most AWD systems also have open diff’s so getting them stuck is easy too. Subaru uses viscous couplings to do the work of diff’s, which I think operate as a kind of clutch system that automate icky uses the pressure of the spinning wheel to divert power. I used to be skeptical of Subaru’s system, but there’s a ton of YouTube vids that show them in action... and it is impressive to watch. The newer method of faux 4x4 is CCB, computer controlled braking already mentioned. Good for most street conditions, but not “true” 4x4.

@dklein8207 — It just that I’ve helped pull several dozen Fords, GMC’s/Chevy’s and Rams out of the mud, ice or snow. They are intended to help with traction on city streets, in mild conditions, and can be a great assist when towing. The Chevy website just says auto-trac or something like that. Not doubting you, just saying that without a center differential locker your power is going to go to the front or rear wheels with the least traction. So if they have a front locker (very extremely rare) and a rear locker, if the front or back wheels break free, you’re stuck in the mud because the center diff is going to send all of the power to the wheels without traction. And bud, I’ve been going off-roading for 45 years now, owned a few rigs, gone on several trips every year, and helped the people in their street vehicles get on their way more times than I can count. People see 4x4 on the side and think my pickup can do anything... not understanding their own trucks systems. As of 2019. The ONLY two vehicle lines sold with true 4x4 systems, with locking front, center and rear diffs were 1. Jeep Rubicon models, and 2. Mercedes G-500 series wagons. Overseas there are a few others like MAN trucks and whatever, but they aren’t sold in the USA. Doubt me, google it. Everything else sold stock in the USA does not have front center and rear lockers. And don’t misunderstand me, Chevy ZR whatever’s may have locking rear diffs. Great when towing. Not good in mud, sand or ice and snow. Better than nothing, but not a “serious” off-road machine. Sorry.

@breakawayadventures6650 — Yes it did.

@stevey500 — To the best of my knowledge, you can ADD/REPLACE your Chevy diffs with locking diffs. I’ve never seen a Chevy with factory locking diffs front center and rear. My experiences winching many a Chevy 4x4 out of tight spots I’ve never once ran across one with FACTORY locking diffs. I’m getting older, and haven’t kept up with chevy tech, so IF they are or have options available from the factory now… GOOD FOR THEM! I’m not perfect, just saying I didn’t think they had serious factory 4x4 systems as I’ve helped many dolts who “thought” they had 4x4 systems out of being stuck. To the best if my knowledge there are only 2 vehicles with factory F/C/R locking diff’s, the Jeep Rubicon and the MB G-Wagon. Please correct me if I’m wrong. And 2 years… no biggie. 😊

@stevey500 — Ahh, I disagree. If a 4x4 has an open center diff, power WILL go to the two front/rear wheels that lose traction. Subaru uses a viscous coupling that acts like a limited slip center diff. Toyotas uses electronic braking control to force power to the wheels that aren’t spinning.
