This comes up every once in a while and my opinion remains the same until they fix it. It's only half a lift kit. There is no way you could ever get me to lift my truck that high in the air and do nothing about the control arms. That, and you can do an SOA in the rear for about $25 (perches, U-bolts, and beer to trade for the welding), not the $120 or whatever it is they charge for the weld-free kit. It's a clever idea that solves a problem that's not really a problem at all.
