The Revolution Gear & Axle gear package for 1987–1996 Jeep YJ and Cherokee XJ with a Dana 44 thick rear supplies a 4.56 axle ratio and Koyo bearing fitment. Intended as a direct replacement for the thicker Dana 44 rear, this package enables proper ratio swaps or differential rebuilds on those models to match tire upgrades, towing needs, or to replace worn gearing while preserving the Koyo bearing configuration.
