Yukon Gear & Axle YPKGM9.5-PC-SHI Eaton Positraction Shim Kit for GM 9.5 Inch

The Yukon Gear & Axle YPKGM9.5-PC-SHI is an Eaton Positraction shim kit specifically designed for GM 9.5-inch differentials. This precision shim kit allows you to restore proper clutch pack preload in limited-slip differentials, ensuring optimal traction and performance.

Purpose and Function:

Shims are used to add thickness and preload the positraction unit with higher breakaway torque, and are placed either between the clutch pack and the case or between the clutch pack and the large side gear. When the differential housing spins easily, adding more shims to the clutch pack helps restore proper limited-slip function. This kit provides the precise shim thicknesses needed to properly tension the clutch packs without replacing the entire clutch assembly.

Key Features:

• Fits GM 9.5-inch Eaton Positraction differentials
• Features higher quality materials and better manufacturing techniques than OEM to ensure longer lasting performance
• Allows fine-tuning of clutch pack preload for optimal limited-slip operation
• Essential for rebuilding or servicing Eaton-style limited-slip differentials
• Sold as a complete shim kit

Application:

This shim kit is designed for use during differential rebuilds, positraction service, or when restoring limited-slip function to a worn unit. Proper shimming is critical to achieving the correct breakaway torque and preventing single-wheel spin under acceleration.
