Ok, Ive read a lot of topics on the conversion. In fact, Ive read to many, they are all starting to run together and confuse me. What Ive got is an 2006 GMC Envoy denali with the rear air suspension. They are leaking out overnight and need replaced. I am going with the coil spring conversion. I have read that the arnott stuff is overpriced. Ive read that the suncore stuff isnt any good. Ive read that I can get the moog stuff from my local parts store, but I dont remember/cant find the part numbers. I also dont trust the counter guys enough to figure it out. What I would love is the correct part numbers for the rear springs I need and the rubber isolators. Also, while Im there Im thinking I might as well change out the shocks. Should I get the stock shocks, or will I need something special after the new springs are installed?
