Yea I think it was a 4 inch block now that I think about it, I really need to drop the front end down a tad bit because the alignment wasnt the way I wanted but it drives good as far as in 2wd but when I get into 4wd it shakes at higher speeds which makes me wonder if I sould have gone to a longer axle, the only reason I didnt was that skyjacker never said anything about it but most other lift kit brands said I would have to if I wanted to go over 35 mph in 4wd. I just like the way the truck looks being level but if theres any way of going bigger with out screwing to much up id be nice!
