yes just make sure you get a k member that will accept stock a-arms and has spring perches. YOu can also run tubular a-arms instead of the stock ones as long as they have spring perches and k member has spring perches. It's usually an option when you purchase the kits
no problem.. I ran thier kmember and stock springs and a arms for a long time... love it, helped weight transfer a ton, and rode just fine esspecially compared to how it rides now with the a arms, coilovers, lakewoods, and kmember spacer.
