So the Airlift site shows to use the 60779 Airlift 1000 kit for Envoys, however I'm going to be installing the Belltech 3" rear drop springs. I'm assuming I need a different kit since the height of the spring is going to be different. Just wanted to know if anyone is already running the 3" belltech rear springs with the Airlift 1000's, and if so which one fits? I would email them spring specs but apparently it's back ordered till Sunday so I won't be receiving them for like a week or so lol.
