Figured I'd ask here before creating a dedicated thread...

Presently I'm sitting at stock height front, about a 1.5'ish drop in the rear which has me sitting about dead level eliminating that factory rake.

At some point the plan is to do a 2/3. Doing a 3 on the rear, are the shorter sway bar links needed? I've seen statements both ways. Not needed until 4+, or needed at 3 also.

If the reigning consensus is that even at 3 it's better to have them, is there anywhere to get just the end links? Apparently Tony no longer has/can get the DJM ones. DJM seems to only offer them in a kit. Maybe those two things are related.

'08 Yukon Denali (so 6.2)

For the passenger side I used a Dorman part # 523-240 (the OEM p/n is 23104735)

For the driver side, there isn't a non-OEM option so I used the OEM one, p/n 23104736.

The driver side mount is a little more difficult to find for some reason, and not sure why Dorman would make one but not the other, who knows. Of the two when removed, my driver side one was definitely more worn out.

Passenger side has two threaded studs that pass through the mount pad on the diff secured by nuts and looks like this:



Driver side isn't as flat like the passenger side, is thicker, accepts bolts that pass through the diff carrier case, and looks like this:


You can buy the four bushings cheaper, but then you have to press them out/in after removing the mounts. A little more expensive, but less work/easier in my opinion to just get the whole brackets.

Not a hard job to do, just a little time consuming (at least for me) getting the driver side bracket out. Less room on that side coupled with a thicker and not exactly flat/straight chunk of metal results in lots of twisting, prying, shifting, raising/lowering of the diff to snake it out. Passenger side is super easy.

Just changed out the passenger side O2 sensor. Can't get at the driver's side from underneath, will have to go in through the wheel well another day as we ran out of light.

Magnaflow Y-Pipe moved the sensor just enough to make removal all but impossible from underneath even with an O2 sensor tool. Previously, I'd never had a problem with a 7/8" wrench; the engineers always left enough room to get a wrench in there to loosen or tighten them.
