I mistakenly ordered new Delco Z95 vs. Z55 rear shocks for my 2011 AV LTZ and installed them prior to realizing they were the wrong ones. I have no errors and the air leveling/ride works fine. Does anyone know the difference? Someone from a Tahoe Forum said "Per Robert at Arnott, the Z55 & Z95 are the same suspension units. Cadillac cleverly created a new part number and began calling autoride magnetic to justify charging a premium for high line parts." Rather then tearing my truck back apart to change them out with the correct ones, I would like to leave them installed, but don't know what issues they may cause, anyone?
