Just got my truck back from the shop after they installed the 501's and aligned the front. Looks like I could have done the install, but it would still need to be aligned, the toe was out on both sides and the camber on one side. I set the 501's at 2" and right now I'm at LF 38 1/2 RF 38 1/2 LR 38 3/4 RR 38 1/2 don't know how I came up 1 /4" more in the LR as the garage floor is level. The ride is firm not harsh, I also have Fox shocks in the rear. I'm just hoping the front settles about a 1/4" lower as I only have 20 miles on the install.
