I picked up my Jeep this morning after having a Dana 44 rear axel swapped in and both differentials re-geared to 4.56. All I can say is "wow!" A complete night and day difference from running the 33's on the stock 3.07's. Not only can I use 5th gear again, my Jeep will accelerate while in 5th gear. This upgrade was well worth the money spent. Thanks to all on this forum for the helpful advice and information.
