If you have 3.92 and above gears, then you won't need a new carrier. If not, then a new carrier is about $80, give or take. I can get you the whole kit and kaboodle (including carrier) for right around $485, give or take for shipping. Installation is your worry, unless you want to drive down here to Mobile, then I will do it for a minimal fee, say $200 for both axles. Gotta hook up my Ram brothers, right? :wink:
