Yukon Gear Replacement Bare Case For GM 8.5in & 8.6in Yukon Dura Grip

This Yukon Gear & Axle replacement bare case is cast and machined to exacting specifications, ensuring tight tolerances for a long and reliable service life. It's designed specifically for the Yukon Dura Grip positraction differential and fits GM 8.5-inch and 8.6-inch rear ends. This case is built to handle the demands of your drivetrain, providing a solid foundation for your differential's internal components.

You'll find this case fits both 28 and 30 spline axle applications, making it a versatile option for many GM trucks and SUVs from the early 80s through the early 2010s, including popular models like the Chevrolet C1500, Cadillac Escalade, and Buick Rainier. It's important to note that this is a bare case and does not include spider gears; it is intended as a replacement for an existing Yukon Dura Grip unit, not as a direct swap for a stock open or factory limited-slip differential. Ensure your axle ratio is 2.73 or numerically higher for proper operation.
