Yukon Gear 8.5in GM Extra HD Standard Open Case (Uses Larger Bearings)

When you're rebuilding the drivetrain on a GM vehicle with an 8.5-inch rear end, a strong differential case is crucial. This Yukon Gear & Axle Extra HD Standard Open Case is built to handle the demands of daily driving and more. It's designed to fit a wide range of GM trucks, SUVs, and cars from the 1970s through the early 2000s, including popular models like the Chevrolet C1500, Buick Regal, and Cadillac Escalade.

What sets this case apart is its construction. Yukon casts and machines each unit to tight specifications, ensuring both strength and precise tolerances for a long service life. A key feature is the larger carrier bearing journals, which significantly increase the case's strength, making it a solid option for applications needing more durability than a standard case. This particular case is intended for use with 2.73 and numerically higher gear ratios and is loaded with its spider and side gears.

This is a standard open differential case, meaning it will function like your original equipment in normal driving conditions. If you're looking for a well-built replacement differential case for your GM 8.5-inch rear axle, this Yukon Gear option offers improved strength with its larger bearing journals.
