this is what I picked off from eBay. The coil springs bolted up perfectly because GM hasn’t change the rear frames of these trucks for almost 20 years I left the rubber coil spacer in at the top and after a couple hundred miles everything settled and it sits perfectly level at exactly 2 inch drop. It rides really well to and with a load of people it does really well. Just one tip, there’s two different springs, one for the models with auto ride with the air shocks and one for the models with just the basic premium ride. The ones here are the ones for models with the premium ride suspension without the air adjustability.
and honestly having it down 2 inches really helps with loading and unloading. The rear hatch height isn’t a big of a deal because I’m only 5‘7“. But for those closer to 6 feet in height they’ll have to duck their head a little bit.
