8 bolt hub?

[traveldadof3]

Hi everyone, I'm new here but couldn't find much to help me figure this out.

Alright, now that that's out of the way. I recently purchased a used 2015 Yukon XL Denali. I didn't really notice anything unusual about the wheel hubs due to a cover on them. I have now noticed that my wheel hubs are 8 bolt as opposed to the standard 6. Could this mean that the previous owner had the axles swapped out for 3/4 ton axles? I also noticed I have a shiny aluminum rear drive shaft. Is that normal on the Yukon Denali? When I was looking over the car at the dealer I did notice that it had a class IV hitch as well. I assumed this was standard. However now I'm wondering if this was also upgraded.

I guess what I'm really asking is, is it possible the previous owner attempted to upgrade my Denali to a 2500 version? If so, would that change my towing/ payload?

Thanks for everyone's help on this!

Please post a picture of your RPO sticker in the glove box. Also, go chat on the GM Customer service website and ask for your build sheet.

Now just to make sure I am understanding correctly, the rear axle has an 8 lug pattern and the front of your Yukon has a 6 lug pattern? If both front and rear are 8 lug you simply have a 3/4 ton truck. No way anyone would chop apart a 1/2 ton suspension like that it just would not be worth the cost. It would be a bear to even adapt a 3/4 ton rear axle much less do the required mods for the front . Naw you just got a 3/4 ton truck I think. Post some pics if you have some. Sounds like a cool rig.

No, both front and rear are 8 lug.

I'll get some pics in the morning. We like it. Well, my youngest keeps saying we should jack it up or add wheel spacers, but he's 13 and just wants a big truck.

all we need is the vin number and the details can be checked to verify

Unless its a 2500 then it should have 6 lug. Towing would change if they changed the suspension also. Im also guessing but the gear ratios would be different in a 2500 too. Like the others said your vin will tell.

You must have a 2500. Sometimes there is no badge.
