I got the 6/7 kit from crown. Issue i had was the shocks they sent me were too short. Kind of a wierd deal i had going on if you can find the thread "rear flip issues" you can read all about it.Also in addition to kit had to buy u bolts, plates (could of reused originals but figured might as well get new). No complaints on quality of products everything seemed well made and fabricated. And there prices are pretty good to. Haven't installed front coils or spindles yet. Gonna wait till i get bigger wheels so i dont have to modify lower control arm.
