Its comes with the 9.76 axle, which according to another post on here comes with the 6.2 and according to that post it looks like the 3.0 as well.

So it is the "heavier" axle? just not the lower gears?

You would probably have to find a dealer that would be willing to work through the problem with you.  They will probably charge a pretty penny for it but they might be able to say that they changed th

No you can not get the sticker changed, it is connected to your VIN when it is assembled at the factory.  Honestly you bought too heavy of a trailer man, if you're 8800 loaded, I can guarantee  your t

I just saw that other thread about the 9.76s...leave it to GM to print ONE thing and DO another!  haha  It makes sense, as the high torque of the 3.0 and 6.2 are definitely suited to the 9.76, but I was just going off what GM itself had in print.  Reminds me of the old days when OEMs would have surpluses of this axle or that axle and just stick in what they had laying around!

Is there a sticker or something that I can look for to see which axle it truly has?

If you want to know for sure, get underneath and look at the casting numbers...otherwise, you can email GM and get the build sheet with all of the specific RPO codes for your truck.  But easiest is to just get underneath and look...see the other pictures in this post.  Directly behind the pinion, on a casting rib in the axle housing...

Interesting, just got under my 3.0 Duramax and it has the 9.76 diff too.

So the 9.76” is the heavier rated axle housing? I know springs and the sticker give it it’s rating, but if I did get airbags the axle is good to go, in theory.

Lucky!  Wish they had that package for LTZ, I need power folding mirrors to fit in the 1 car garage door.

Your sticker has a RGAWR- Rear Gross Axle Weight Rating.  I would hesitate to exceed that.

For sure, that # has a lot of room left on it.

Just wanted to show you that my little 4253lb dry travel trailer was able to put me over GVWR and over RGAWR with my family and all of our gear.  I’m going to have to remove and/or move a lot of junk into the trailer to be able to make my truck legal.

Thanks, I do need to weigh it. And also that’s why I will be going to a 2500 sooner than later.

      2027 GMC Sierra: Official Discussion

      Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.

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

      By bluev8 · Posted

      New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.

      No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.

      - I like the outside but not as much as the Chevrolet.  They ICE'd the EV styling and it works, but I think exterior goes to Chevy on this one.     - SLE and SLT dead = Not.  Surprising.  Fits into the rest of the GMC lineup like this which (aside from Pro) matches the rest of the family.  Elevation, AT4, Denali.     - Interior.  Sophisticated Malaise era.  Why do I say Malaise?  Drawn with a ruler.  Rectangles everywhere.  Looks very premium though.
