4.88 Ring & Pinion Gear Set

The Yukon high performance ring and pinion gear set represents a benchmark of quality in the automotive gear industry. Engineered with state-of-the-art design and advanced heat-treating techniques, these gears ensure structural integrity and surface finish meet exacting specifications. This specific set is designed for 2015 and newer Ford 8.8" F-150 and Mustang applications, featuring a 4.88 gear ratio. Installation compatibility requires a 3.31 - 3.73 carrier case with a 2.400" deck height. It is important to note that a new carrier case is necessary when replacing a factory 3.15 ratio differential. The 2015+ Super 8.8" axle, used in these vehicles, features larger pinion bearing journals and pinion splines compared to earlier Ford 8.8" gears, ensuring enhanced durability. Yukon offers a wide selection of gear ratios to optimize traction performance, accommodate increased horsepower, or support larger tire upgrades. Additionally, Yukon provides a Y.E.S. Plan, a lifetime, no-questions-asked protection plan for the gear set.
