Gear & Axle (SK CSGM8.5) Crush Sleeve Eliminator Kit For GM 8.5 Differentia

Crush Sleeve Eliminator Kit for GM

This crush sleeve eliminator kit replaces the standard collapsible pinion spacer in compatible differentials, referencing part number SK CSGM8.5.

Overview

This crush sleeve eliminator kit provides a solid spacer solution for maintaining pinion bearing preload. Designed for high-stress differentials, this crush sleeve eliminator kit prevents pinion nut loosening during heavy acceleration. Mechanics rebuilding differentials will find this crush sleeve eliminator kit essential for a reliable build.

Built For Performance

• Precision-machined steel spacer ensures consistent pinion bearing preload
• Includes a variety of shims for micro-adjusting bearing clearance
• Eliminates the risks of over-collapsing a traditional crush sleeve
• High-strength construction resists deformation under severe torque loads

Fits These Machines

• for GM 8.5 inch Differentials

On-The-Job Use

• Rebuilding and setting up performance 10-bolt rear axles
• Preventing pinion bearing failure in drag racing and off-road vehicles
• Replacing worn factory crush sleeves during differential gear ratio changes

Good To Know

Q: Why use a crush sleeve eliminator kit instead of a standard crush sleeve? A: Solid spacers do not compress further under high-torque situations, maintaining accurate pinion depth and bearing preload over time.

Q: Does this kit require professional installation? A: Yes, setting up a differential requires precise measurements with a dial indicator and specialized tools to ensure proper gear mesh.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
