578793C91 Dana Spicer Gear Kit Set 5.38 Light Axle

The 578793C91 Dana Spicer gear kit set is a 5.38 ratio ring and pinion gear kit for light axle applications. The 5.38:1 ratio puts the axle on the deeper end of the gearing range, favoring pulling power and startability over top-end shaft speed, so ratio matching matters when you replace a set. Gear ratios must match side to side on a tandem and match the mating components in the carrier, so confirm the ratio stamped on your existing ring gear before ordering. Not sure this is your part?
