I bought a set of 4inch skyjacker lift springs from a guy online. I have received them and 2 of the springs are 2.5 inches lower then the other 2. :-\ So it looks like i have 2 2.5inch springs and 2 4inch springs. This wont make the truck sit level will it? I thought the 4inch lift kit from skyjacker had 4 4inch lift springs? :-[ Is this kit maybe made for a shackle reversal? Do the pro's out weight the cons for shackle reversal on a daily driver? Thanks Rob.
