The Yukon Gear & Axle Dura Grip limited slip differential case is engineered for Ford 8.8-inch rear axles with 31-spline axle shafts. This bare case provides the foundation for building a high-performance limited slip differential using your choice of clutch packs and spider gear sets.

Key Features:

• High-strength nodular iron construction for maximum durability under demanding conditions
• Precision CNC machining ensures proper tolerances and smooth operation
• 31-spline configuration for Ford 8.8-inch applications
• Bare case design allows custom clutch pack and spring setup
• Accepts standard spider gears, clutch plates, and preload springs (sold separately)

This Dura Grip case is ideal for rebuilding worn limited slip differentials or upgrading from an open differential.
