Description

The USA Standard Gear ZG D44R-456R is a replacement ring and pinion gear set specifically engineered for Dana 44 reverse rotation differentials. This set offers a 4.56 gear ratio, a 26-spline pinion, an 8.50-inch ring gear diameter, and utilizes 10 ring gear bolts. This evaluation process ensures that each set passes essential dimensional, material, and fitment testing. These gears are intended for front axle applications with reverse rotation Dana Spicer 44 differentials, including straight axle and Independent Front Suspension (IFS) models from '92 and older, as well as '93 and newer IFS. This ring and pinion set is compatible with a wide range of Ford vehicles equipped with Dana 44 front reverse rotation axles, spanning model years from 1966 through 1996, including Bronco, F-150, F-150 1/2 Ton, F-250, F-250 3/4 Ton, F-350, and F-350 1 Ton models.
