What up guys.

 

I'm just wondering if an axle swap is possible. I want the 3.0 and Front/Rear lockers. Looking for any thoughts/ideas/opinions from the experts.

 

Thx in advance.

You'll probably save money by installing aftermarket lockers and the SSV shocks. IF you can find the axles in a salvage yard, you will be paying a premium.

there are no aftermarket lockers for our trucks yet, so your only option is to fit the ZR2/AT4X diffs to your truck.  Being electronic lockers, it shouldn't be too hard to wire them up to an aux switch panel.

I couldn’t find any aftermarket lockers that are offered for this generation of the Sierra/Silverado.

Some guy on the Duramax forum reached out to Auburn gears. Sounds like they're making one for the 1500/2500/3500's. Limited slip and e-locker. Dunno the eta

Just curious where you’ll even get axles. 

 

That's a future me issue, after I figure out if it would work...haha

I'm curious what Auburn gears is planning to do for the front differential. I've heard mixed things about the carrier possibly being welded. If it's not, then I'm not sure what the delay has been for aftermarket gear companies.

I'm not sure, the guy hasn't responded back on the other forum. Usually lockers entail replacing the whole carrier anyways. Or do you mean the gears are welded on? That'd be insane, pop your cover open and let us know.

There’s not a lot of guys wheeling these trucks hard. They’re also relatively new with new axle designs. If this was a Jeep with Dana 44’s or these axles were the same as other more established axles they’d have more options a long time ago. 
 

The gears aren’t welded to the carriers. That wouldn’t make any sense from a functional or production standpoint.

But not need. The front has a traction-based system that will get you and pretty much 99.98% of any situation that off road these trucks will find themselves in. For a front locker to be useful it has to be in an extreme situation that no one but a small handful of people may put these trucks in. Save the money and time for other things that are more useful. Unless you want it for a talking point, there are much better things to spend money on that can be actually used.

Probably a use/necessity thing. These trucks even though they sell in high numbers aren't put in situations where people are clamoring or utilizing a front locker. Why design something so few will use? It isn't like a midsize where maybe 20% off road, full size trucks just aren't trail vehicles and those front lockers are pretty much useless when they already have a traction system up there. Comes down to a business case. These are more for towing and hauling and ranch work, mid size trucks are more for the hard core trails that might necessitate one.

I had a 72 K20 with detroit lockers front and back that was uncontrollable on snowy roads due to the front locking so lt wouldn't steer. Eventually it climbed a snowbank onto a telephone pole and landed on its roof. After replacing the cab I removed the front locker and never missed it

      Trading 7.3 (Godzilla) for G.M.C gas

      By James Beyer · Posted

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
