Yukon 11.25in Dana 80 4.88 Rear Ring & Pinion Install Kit 4.375in OD Head Bearing

The Yukon Gear & Axle YGK2177 kit is built around a 4.88 ratio ring and pinion gear set specifically for the Dana 80 rear axle found in 1999-2016 Ford F-350 Super Duty trucks. This kit is designed for those looking to re-gear their differential, whether you're adding larger tires, increasing towing capacity, or simply replacing worn-out factory gears. The 4.88 ratio is a popular choice for significantly larger tire sizes, helping to bring your engine's RPMs back into a more efficient range on the highway.

Inside this comprehensive package, you'll find not only the high-performance Yukon ring and pinion gears, but also a complete Yukon Master Install Kit. This means you get all the necessary Timken bearings, seals, gaskets, and small parts required to properly rebuild your differential. Yukon engineers use advanced heat-treating techniques and rigorous testing to ensure their gears meet exacting specifications for durability and smooth operation. The 11.25-inch ring gear diameter and the 4.375-inch OD head bearing are specific to the Dana 80 application, ensuring a correct fit for your Super Duty's rear axle.

Choosing a complete kit like this saves you time and money by consolidating all the essential components into a single part number. This makes the re-gearing process more straightforward, getting your truck back on the road with improved performance and efficiency. Yukon also backs this kit with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for peace of mind.
