So my neighbor just bought a new Chevy Colorado with some squirrel diesel ZR-2 and tells me HIS truck is a "real" four wheel drive and my Silverado Z-71 (I have the original window sticker that says Locking Real Differential" tells me it is not. i don't get it.. Over to you experts to enlighten me...

He's probably a little confused. Don't know about the Colorado, but I do know that some GM trucks had permanent All Wheel Drive, and others had a selectable "Auto 4WD" mode, that would engage the front axle automatically in low traction conditions. The more traditional trucks had 2WD, 4WD and 4WD Low selectable modes with a conventional transfer case that locked the front and rear axles together, fine for off road but hard on the drivetrain on solid surfaces. True AWD (All Wheel Drive) uses an open transfer that allows different front and rear driveshaft speeds, fine for all surfaces. If that's what he has, then I guess he thinks he's special

To anger a conservative, lie to him. To annoy a liberal, tell him the truth.
The Colorado ZR2 comes with a locking rear differential (activated electronically) as well as a selectable locking front differential. Thus, "true" four wheel drive. If you don't have locking diffs in both axles, you can't count on getting power to all 4 wheels. A few other factory 4x4s have this, mostly Jeeps with the Rubicon package, and Ram Power Wagons.

The electric locker is the ticket in any truck front and or rear, the GM locker in the their 15-2500s will lock but only after spinning for a bit and then will unlock at about 20 mph, at times my old truck would stay locked at slow speeds chirping tires on corners.
So yes what he is saying is somewhat true if he has the electric lockers and the diesel with a good set of tires his little truck is a pretty serious off road contender.
Like K1500 said though I wouldn't let it worry me much, you can haul a larger suit case than him and get out of the way of traffic if you need to.
Real 4x4 trucks should have locking differentials, but they should also be solid axles. IFS is fine for sand racing and pavement trucks, but lockable solid axles are what constitutes a real 4x4 to me.

You should go buy a Unimog to one up him. Or stop worrying what a neighbor says. BTW it’s locking rear differential, not locking real differential.
Thanks for being a psychic or appealing to your estrogen clairvoyance. In case you missed it (you did) it has nothing to do with one-upsmanship, but rather a technical question, but on the plus side, you have the rectal orifice schtick down pat...

This makes it easier to understand, especially the electronic locker. Mine just says "rear locking", thank you

Didn’t mean to offend, the UNIMOG thing was obviously a joke. In all seriousness what I read is as follows:
1. Your neighbor says HIS truck is a ‘real’ 4 wheel drive and your Z71 with a G80 locking rear isn’t a ‘real’ 4 wheel drive. 2. You don’t get it and want to be enlightened. Is that correct?
My opinion (and the point of the UNIMOG joke), he wants to engage in a ‘my truck is better than your truck’ argument for self gratification. Any vehicle without a locker on the axle could be viewed as 1 wheel drive on that axle, but no one says it that way. You don’t see a car with an open diff and say “there goes a 1 wheel drive car”. Yes. He has a locker front and rear and you have a locker in the rear only. So I suppose he means you have a 3 wheel drive.
But what he really means is he wants to get in a d*** measuring contest with you. I don’t ever see a reason to go down that road, especially with an idiot of a neighbor. The only way you can ‘win’ a contest like that with your neighbor is to go get something that is so clearly superior to his new toy he will shut up about it. Obviously that’s foolish, which is why I would just smile and nod when he starts engaging in a ‘my truck is better than yours’ discussion.
Center diff lock is for AWD vehicles (not 4WD), which have a center diff that allows a power split between front and rear axles. This is so the vehicle can turn easily. You lock the center differential on these vehicles in low traction and they become equivalent to a regular truck in 4H.

Sorry I jumped on you then,

Nailed it!
I love the ride on my 18 Ram, but I wish it had a solid front axel.

You should have asked him what he means. He's likely the only one that would know that.
To have all four wheels fully engaged, you need lockers front and rear. Maybe he meant he had a front locker as well as a rear. Maybe he's just crazy. IDK

... or you could throw a football at his groin.
