I want to move my axle forward and lift my truck enough to clear 38.5's so what I am wondering is what springs are better, waggies or rears? also by running either of those springs I am wondering what to run in the rear. I was thinking of running f150's, chevies or marlin springs in the rear? I want flex and lift without cuttin up my truck! details please like what shackles, X member, block etc. Thanks Cody
