Looking to lower my 05 KC and i see several people using the McGaughy 2/3 kit. I see that belltech also makes a 2/4 kit with shocks. Just wondering what you guys reccomend. Also i was reading something about having to make shims for the rear end so it doesnt bind the driveshaft. If anyone can give me some suggestions on the best kit to go with i would appreciate it. I just want it done right and dont want to get the wrong thing.
