I have 2014 AWD XL Denali
Like to "beef up" the rear diff/axles/ etc if possible.
I did order a new cover that is the cast aluminum last summer in hopes
that the bearing caps preloads along with extra fluid would run cooler...
But , IT Won't Fit with panhard bar, etc... It was the low profile one and still would
not clear
So, What are some options:::?????

I've seen the 2wd versions have the 9.5" Ring Gear.. But don't know if its a direct fit or what.
I have the load leveling air suspension, ETC Also, my gear ratio is 3.42 w G80 Posi

I just don't want to trash out a perfectly good rear end (I'll be towing a lot) if
I can upgrade or replace and recoup some of my money by selling my current rear axle assembly.

Thanks !!

the ta performance rear diff girdle and a QA1 panhard bar will fit, I also put spohn boxed lower control arms and mevotech upper control arms, hellwig sway bars front and rear.
if (when) the G80 goes out then I will put in a Eaton Detroit.
@Rocket Man has some info on that also.

I tried the TA rear diff girdle/cover and could NOT make it fit with
panhard bar/ Etc...
I took my cover off, spare tire,, etc and did everything I could to try to
get it to fit with No success , so I sent it back.

So, Am I wasting money if I replace the axles with aftermarket, put in
a better posi/diff unit,, etc
Or try to find a 9.5 " rear axle assembly and make it fit ???

OH, Yes.. Ive got the helwig front and rear bars to get on still. And I
was going to do the Spohn lower boxed control arms - I talked to them...
Those items help firm up and keep everything from shifting around during heavy towing.
But I'm worried about killing the actual rear end - or am I worrying about nothing ???

The 14-Bolt is a direct replacement provided the donor was a RWD Denali, Avalanche (6.0) or Escalade.

You could also replace the center chunk with an Eaton Trutrac limited slip.

I was on Spohn website and just saw the "tubular adjustable " one.. When
I talked to them a while ago they said for my appl I wouldn't need it as
I'm not changing the ride height..

Doubelieve, That looks really good... I just could not make it work with
the factory panhard.
I'll look into the QA1. They make pretty good stuff.
You don't happen to still have a part # ???
