I've read around a little on here, but thought I'd put up a thread as I searched. I've got a 4x4 2010 king cab and wanna go up 4". Can't use the shackles because of the 4wd, so what're my options? I've seen 3" and 5" kits. Are there any 4's out there that are kitted, or do you have to just put them together yourself? If so, what components have y'all used?
