Yukon 10.5in Ford 4.56 Rear Ring & Pinion Install Kit 35 Spline Positraction

Starting with the 10.5-inch ring gear diameter, this Yukon Gear & Axle kit is built for serious work. If you're looking to re-gear your 2008-2010 Ford F-250 Super Duty, perhaps to handle larger tires or improve towing capacity, this package bundles everything you need into one part number. The 4.56 ratio is a popular choice for trucks that see a mix of highway driving and heavy hauling, offering a good balance between fuel economy and low-end grunt.

Inside this kit, you'll find not only the Yukon ring and pinion gear set, but also a complete Master Overhaul Kit. This means you get high-quality Timken bearings and all the small parts necessary for a full differential rebuild. It also includes the Yukon Dura Grip clutch-style limited-slip differential (LSD), which is fully rebuildable and designed to put power down effectively, especially when traction is limited. Yukon engineers use advanced heat-treating techniques and rigorous testing to ensure these gears meet exacting standards for durability and performance.

This kit is designed for applications with a 12-bolt rear cover and a 12-bolt ring gear, common in the specified Ford Super Duty trucks. Yukon also backs these kits with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for the gear set, giving you extra peace of mind for this significant drivetrain upgrade.
