4.70 Ring and Pinion Gear Set

The Yukon Ring and Pinion Gear Set is engineered to be a high-performance upgrade or replacement for your Dana 44 M220 rear differential. With a precise 4.70 gear ratio, this set is designed to optimize your vehicle's traction and performance, whether you've increased horsepower or upgraded to larger tires. Yukon Gear & Axle utilizes state-of-the-art design, advanced heat-treating processes, and leading-edge quality control to guarantee that each gear set meets exacting specifications. This commitment to quality ensures structural integrity and a superior surface finish, making them a benchmark in the automotive gear industry. Installation of this gear set may require a programmer for the ratio change; failure to do so could result in the vehicle entering 'Limp Mode.' Additionally, for Broncos with factory 3.73 or 4.46 gear ratios and a standard open differential that features a welded gear/differential, a differential replacement will also be necessary. It is recommended to consider a Master Overhaul Kit for a more straightforward installation process. Backed by decades of experience, Yukon products are a trusted choice among automotive professionals, racers, and enthusiasts worldwide. Yukon also offers an optional Y.E.S. Plan, a lifetime, no-questions-asked protection plan for your gear set.
