Well, I may have found as big of a lift kit as I am going to find for my truck (as well as the only kit I could find). It is a Fab-Tech 3" in front and 2" in the rear. The only thing that concerns me is how this kit lifts the truck. It relocates the upper ball joint from bolting through the top of the upper control arm to below and adds a 3 " spacer between the arm and ball joint. It also adds a 3" lift spring. The 2 things that concern me are 1) adding spacer on one of the most crucial points in the suspension, and 2) wouldn't this increase the angle of the lower control arm thereby decreasing the travel room of the lower ball joint? How reliable of a lift kit would this be? Granted, it is the only suspension lift kit I can find, but if this type of lift is not reliable, I will just go with a body lift. Of course, if this kit is CK5 approved, I may still get a 2" body lift to get the 5" that I was hoping for.
