Rancho, when I put them on my wife's truck had just change the length on the front end for 4x4 2001 in their new catague. the orginal front shocks, that 4 wheel suppled looked short to me , they were correct per their catogue, however Ranhco newest catagoe now recomends a longer shock, I exchanged within a week and they longer one worked a lot better, it took 150 footpounds of torque to pinch the lower fronts close to get rid of the rattle. I really like them so far, 5 seting in front, 2 in the rear. About 20,000 miles so far.
I purchase a second hand in the cab kit to install, but have never need it yet. as the rears are easy to get too.
