Howdy. Yes I have read the what lift do I have thread and things just don't seem to add up. I have measured the front springs at 17.5" and the rear springs are 13", which would equate to a 5.5" lift. I have found part numbers on the shocks and they appear to be old Pro Comp E3000 series with part #323509 (rear) and 324510 (front.) According to the interwebs these shocks are for a 4" lift on the rear and 2-4" on the front with these part numbers. This thing also has the transfer case dropped skid plate (without the linkage drop) and the lower control arms are definitely not factory due to them being tubes and manufactured with a bend in tjem to adjust the rear pinion angle. Any thoughts on if this is a 4", 5.5", or 6" lift? Also given the existing shock part numbers what would be recommended replacements?
