Ok, I've got 2.5 yrs on my 4inch skyjacker short arm lift and it's served me well (after I scrapped the t-case drop brackets and bought a double cardan rear drive line, and adjustable uppers, and an adjustable track bar). However, it's time to bite the bullet and do it right. I'm running 285 75 16s and don't want to go any bigger, but I'd like a little more clearance. I'd like a 5 or 5.5 inch lift. I'm hoping for a smoother ride, actually, as the articulation doesn't matter quite as much to me. Any one have experience with the RE or Terra flex kits? Any other first hand knowledge?
