Hey gang, What's the maximum lift on these front suspensions on a 2500 without causing the upper "A" arm coming in contact with the spring perch ?. I don't want to change out spindles because then I'll need to purchase new wheels with less backspace, just want to do it with new springs and or spacers. Can't seem to find much info from other members lifting their 2 WD Rams. Yes I said 2WDs, lol.
