The JK 44 axles are a steal for the price I think. The axle tubes are small...I have seen two or three people break a tube...and the C's seem to like to bend with bigger tires. Off road evolution has some brackets you can weld on to reinforce the C's tho. The locker does a pretty decent job, I think they are like anything else...there are always a few issues here and there. Also, it is easy to hook up a switch to activate the locker.
