The Yukon 8.8" Ford 3.73 rear ring-and-pinion master install kit pairs a 3.73 ratio ring and pinion with bearings, seals and the small parts required to rebuild a 10-bolt 8.8" Ford rear. Yukon uses advanced heat-treating and quality testing, and this combo includes Timken-level bearings and Yukon’s Y.E.S. lifetime protection plan to simplify re-gearing for larger tires, towing or worn gears.
