The Yukon Ford 10.50" 4.30 ratio ring-and-pinion gear set is a direct replacement for 1999–2010 Ford 10.5-inch differentials when a taller numerical ratio is desired. Yukon engineers finish the gear tooth surface to reduce friction and heat and use advanced heat-treating with high-grade steel for durability. The set features a 10.50" ring gear with 12 bolts and a 31-spline pinion at a 4.30 ratio and is manufactured to OEM fitment standards with Y.E.S. coverage.
