yes, you keep boxes 10 years after you buy a product.
a ratcheting locker, if you would ever see one, uses springs to compress 2 gear looking things onto a center plate. on the side of the gear things that face the plate, they have a set of teeth or pins if you will. These cause each side to mate appx 5* offset from the other side into the center plate into sets of grooves that are wider than the pins. this allows the axle about to speed up get a head start to cause by force the gear thingy to push away from the plate - hence the cli-clunk cli-clunk noise. (unless you are going fast and it sounds like spinning a ratchet - the kind that works sockets)
the center plate is nothing more than this grooved plate with large pins in the shape of a bearing cross that hold this all in the carrier housing. simple. been around since 41. completely bought and owned by eaton corporation and no one else.
there are no actual gears in it, other than the oce sided gear like things. there are no clutches.
a limited slip - as the name applies - will prevent the wheels from turning at different speeds until a preset TORQUE differential is applied (they call it breakaway torque) its fairly pitiful. (I think our ford trucks are specced to fail and replace the units at 80ftlbs)
the ratchet, when torque is applied, locks SOLID like a spool. the ratchet becomes open only when axle speed differentials are encountered. from a dead stop, the axles move at the same speed
cmon, this stuff is not rocket science and its all over the web, which begs, why is this a topic? your posts have thrashed today from telling us the device did not exist, to it was never offered in gm, to it was never built by its company, to its insides are completely different than reality. WTH?
I beleive you will also find the detroit name is used because of eatons relationship with GM. I previously thought it was a separate company. eatons webiste btw, lists all the companies and divisions they bought and sold over thier history.

I will let you live with your locking rear axle. Heck I have what I would call a limited slip rear axle from the factory in my truck which is a 04 f250 4x4. Although it does say locking rear axle on the spec sheet and I have cracked the rear to change the fluid once this year and I can plainly state as with all of my previous trucks it has a limited slip. Now my 91 cherokee..... It is a locker and looks totally different. And drives way different

I'm not brand centric and have owned all of the big three. Currently an 09 GMC 2500HD w/ Z71. It's a great truck. I like having IFS and don't think it's a disadvantage offroad...otherwise the Humvee and Landcruiser wouldn't have IFS. now, the latter two likely have beefier stock tie rods.
I don't think the offroad packages should be available on 2WD models for any of the makers- it's just for pose appeal. Also, FX4 like Z71 could offer more than it does like taller tires and better shocks. Oh well, I still like the locking rear and skidplates.

Actually, the Z71s have an automatic locking differential, which is better than the limited slip on the FX4. They also have more skid plates and better shocks than the FX4...not to mention 4-wheel disc brakes. If I had to pick a truck ONLY based on it's off-road package, the Chevy would win hands down. I hate to admit that.

A couple of questions.
What does 4-wheel disk brakes have to do with off-road operation? That option, IMO, makes a truck more "car like" for city driving.
and
Snow-ice driving conditions (which is why I have a 4x4) also have nothing to do with off-roading.
The other "package" to mention is Toyota's TRD, or Turd, option. It is also a tire/shock/limited slip/stickers combo. My non-TRD Tundra still has skid plates and decent gas shocks, but not the bright yellow ones. The joke is the TRD Tacoma package when added to a 2WD model. Yes they do that.

anyone who has any mechanical knowledge would know chevy is a far better built truck than ford, tires and lifts mean nothing chevys locking front and rear dif. alone make them a far better off road vehicle why do you think the military uses HUMMER built by gm which has basically the same drivetrain as a z71 because they are beasts, limited slip sucks not to mention the 5.4l is the most underpowered pos engine ever the only way ford makes their engines powerful is with superchargers which destroys the engines life and even with superchargers they are still slower then any chevy in the same vehicle class the company i mechanic for has all fords and i have done 3 trans. on trucks with under 110k 04 models and up not to mention the million other problems they have fords are junk
#53
oh and lubbock you say you would rather have disc brakes in rear, disk brakes are far better performing than drum brakes and most all your braking comes from the front so why would you put the better brakes on the rear...i guess all vehicle manufacturers have my same thoughts cuz you wont find any vehicle with drums on front and disks on back

Weaker axles, lower frame/ride height, a 5.3ltr engine that overheat's when you work it, crappy drum brakes on the back, god awful styling, interior that fall's apart, squat's like my dog with a piece of firewood in the bed, and did I mention the dash and door switches that corrode and quit working, o the abs system that corrodes and make your brakes useless.
FYI They never put a locker in the front from the factory! The locker in the rear blow's apart when you need it, and the 10blt rearend is barely adequate for a cavalier let alone a truck.
Yep Chevy is the greatest! When the world bought them in 2008-present, they shoulda gave us all one.
O the Z71 does have a clapped out version of bilstein's on it. (Just like the clapped out version of rancho's ford uses)
O Chevy tried Disc's on the back for a couple years, their setup and design was a major fail.............kinda like the accounting department!

Oh no the GM fanboy troll is angry.
FYI GM doesn't make the H1 Hummer used by the military, AM General does. They made that bloated mallcrawler H2 and hideous H3 turd. BTW the Hummer brand was deemed so worthless the Chinesse even backed out of buying them so they went out of business.
If it wasn't for the US government GM may no longer be making there turd vehicles anymore. As a matter of fact GM biggest fanboy (Barry O) is trying to bump up the hybrid/electric vehicle tax credit to $10000 so GM can sell more of their junk Volts that catch on fire and go a whole 10 miles on battery power. Must be nice to have the taxpayer picking up the tab so you can continue to put out garbage. The average idiot that buys a Volt has an average household income of $176,000 per year but Barry still thinks they need a tax break to buy a car.

the first thing i think of when i hear off road package is clearance and that is one thing chevy doesnt have its embarassing to even call them an off road package locking diffs do nothing when your saddlebaged.....heck my dads stock 98 f150 xlt sits higher than pretty much every Z71 ive ever seen

1. Ford doesn't build the 5.4L anymore. Yes, it wasn't the end all be all motor but finally Ford killed it and gave the blue oval faithful NEW motors. Can't you still get a 4.8 or 5.3 in a 1/2 ton Chevy/GMC?
2. Superchargers that destroys engine life.....really? I guess I wouldn't want to bet my lucky dollar on a ZR1 or Caddy...seeing they are supercharged....It's not like Chevy to bank such a risk on their flagship vehicles.
At the end of the day...they all have their faults.

...Now what was that you were saying about Ford not being able to make a powerful naturally aspirated engine?
Yeah I know you...Your going to say, (Well I was talking about the 5.4L)...Alright, 5.4L vs 5.3L...Going to sum it up for you real quick.
Yes the 5.3L generally was a little bit faster than a comparibly equipped 5.4L...But who buys trucks for racing in the first place?...The 5.4L ALWAYS towed much better than that guttless no torque 5.3L.
Next time think before you run your mouth you troll.
You need to find a new occupation becausing trolling the internet is not your thing.
