Brinker88, So, you said to go with the 44?  I have a Dana 35 on the rear with a Detroit Locker, and Chromolly shafts.  I know that the Dana 30 isn't the best, but it was what was affordable at the time.  I am running 4.56 gears in the back, and the cost to switch out gears in the front would be almost as much as to change out to the axle.  Any ideas?
