Yukon Gear & Axle has built a solid reputation for making top-notch drivetrain parts, and this comprehensive kit is a prime example of that. If you're looking to re-gear your rear differential for better towing, to handle larger tires, or just to replace worn-out components, this package has everything you need in one convenient part number. It's designed for vehicles with an 11.5-inch ring gear diameter and a 14-bolt rear cover, commonly found on heavy-duty trucks like the Chevrolet Silverado HD, GMC Sierra HD, and Ram 2500/3500 models.

This kit doesn't just give you the gears; it includes a Yukon Dura Grip clutch-style limited-slip differential, ensuring improved traction. The ring and pinion gears themselves are engineered using advanced heat-treating techniques and rigorous quality testing to meet exacting standards, promising durability and smooth operation. You also get a master install kit packed with high-quality Timken bearings and all the necessary small parts, making the rebuild process more straightforward. This means you can get your vehicle back on the road with confidence.

Beyond the core components, Yukon backs this kit with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for the gear set. This offers significant peace of mind for such a critical drivetrain upgrade. When undertaking a re-gear project, having all the right pieces in one box saves you time and hassle, letting you focus on the job at hand.
