The rear is not adjustable, it's basically the same setup as the front - remove strut, bolt on spacer then re-install on vehicle. Same kit several others on here have used but I have not seen anyone else with this kit on a yukon.

When I picked it up they told me there wasn't any complications with the install but it did take longer than the quoted 5 hours to get it done, and getting it aligned afterwards was a challenge. I think it looks much better now and still rides really smooth, maybe a touch more bouncy over big bumps but not bad at all. Just completed a 600 mile round trip and it did great with 3 adults, 2 kids and the back end full of luggage and Christmas presents and whatnot. Here are a few before and after pics...
