Hi, I just got the 4" shakle flip installed and the shocks that came with the kit seem too long to me. With the weigh of the truck on the ground, the shock only has ~4" of travel left before it's fully compressed. Once I put the seats and gear in the back, there won't be any travel left. Anyone have any menasurements for how long the shock should be for a 4-6" lift on a 71k5? The Tuff Country web site lists the part numbers as correct so either they put the wrong shocks in the box, or my truck isn't a stock frame, or one of us is just dumb. Hopefully not the last one.
