If you're looking to re-gear the rear differential on your 2000-2010 Ford F-150, this Yukon Gear & Axle kit has everything you need in one convenient package. You get the 9.75-inch ring and pinion gear set with a 3.55 ratio, designed to improve your truck's performance, whether you're adding larger tires, increasing towing capacity, or just replacing worn-out components. This kit also includes the Yukon Master Overhaul Kit, which contains all the necessary Timken bearings, seals, and small parts for a complete differential rebuild.

Beyond the gears and bearings, this package features a Yukon Dura Grip clutch-style limited-slip differential (LSD) with 34 splines. This positraction unit is fully rebuildable and helps put power to the ground more effectively, especially in slippery conditions. Yukon engineers use advanced heat-treating techniques and rigorous quality testing to ensure their ring and pinion sets meet exacting standards, making them a popular choice for serious drivetrain work.

This kit is designed for applications with a 12-bolt rear cover and a 12-bolt ring gear. It includes 2.99-inch OD axle bearings and seals, ensuring a proper fit for your F-150's rear axle. Yukon backs this kit with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for the gear set kit.
