I'm looking to buy DIY's inboard shock kit. But dont know what kind of shocks to buy. My K5 has 6 inch lift in rear how do I tell how long to get? And do I get a soft shock or a firm shock or remote reservoir shocks???? If this helps I run rocks no mud some dirt trails the ft has the Ford towers and 9012. Let me know what you think before I wast my money on the wrong shocks.
