I've bought them off Rockauto before and used all 3 brands they offered. The AC delco shocks are made by Gabriel, they're the same as the high jackers with a different sticker. The Monroe shocks are junk, there is NO WARRANTY on them (as ridiculous as that sounds) and the last set I bought was assembled wrong, had to twist them to install them which tore the airbag.
I don't recall if the Gabriel/AC Delco set came with it, but you'll need a tee to attach them to your air ride setup, IIRC it was Monroe part number AK16, Rockauto sells that too.
