Ratech 4111 Solid Pinion Bearing Spacer Kit for GM 7.5" and 8.2" Rear Axles

The Ratech 4111 is a solid pinion bearing spacer kit designed specifically for GM 7.5-inch and 8.2-inch rear axle assemblies. This precision-engineered spacer replaces the factory crush sleeve design, providing a more reliable and consistent pinion bearing preload setting.

Key Features:

• Solid construction eliminates crush sleeve failure concerns
• Includes shims for precise pinion bearing preload adjustment
• Allows pinion nut to be torqued to proper specifications without over-compression
• Enables pinion removal and reinstallation without replacing spacer
• Direct replacement for GM 7.5" (1982-2008) and 8.2" (1964-1972) 10-bolt rear differentials

This solid spacer kit is ideal for performance builds, gear changes, or differential rebuilds where repeatable bearing preload is critical. The included shim pack allows fine-tuning of pinion depth and bearing preload to manufacturer specifications.
