Fits select 1967-2015 Chevrolet and GMC C/K series trucks, Suburban, Silverado, Sierra, and Express/Savana vans with the 10.5-inch 14-bolt rear axle.

The Yukon Gear Crush Sleeve Eliminator Kit (SK CSGM14T) is an essential upgrade for heavy-duty towing, off-road use, or high-performance applications. This kit replaces the standard, one-time-use factory crush sleeve with a precision-machined solid spacer and a comprehensive shim pack. By utilizing a solid spacer, you can set an exact pinion bearing preload that will not compress further under extreme torque loads, ensuring the longevity of your ring and pinion set.

Using a solid spacer also simplifies maintenance; if you need to replace a leaking pinion seal in the future, you can simply remove the yoke and re-install it without the risk of over-crushing a standard sleeve and ruining your bearing preload.

• Axle Fitment: GM 10.5" 14-Bolt Truck
• Function: Replaces OE crush sleeve with a solid spacer and shim stack
• Performance: Maintains consistent pinion preload under high-stress conditions
• Included Hardware: Solid pinion spacer and multi-thickness shim kit
• Manufacturer Part Number: SK CSGM14T

Fits select 1975-2014 Ford, Lincoln, and Mercury vehicles with 7.5in or 8.8in differentials.

The Yukon Gear & Axle Crush Sleeve Eliminator Kit (SK CSF8.8) is a critical upgrade for high-performance and heavy-duty differential builds. Standard crush sleeves are designed to collapse to a specific length to set pinion bearing preload, but they can continue to compress under extreme torque or shock loads, leading to a loss of preload and eventual gear failure. This kit replaces the collapsible sleeve with a high-strength solid spacer and a series of precision-machined shims.

By using a solid spacer, you can achieve exact pinion preload by adjusting the shim stack thickness. This creates a more stable assembly that maintains its settings even under the stresses of racing, towing, or off-road use. This kit is tailored for Ford 7.5" and 8.8" applications to ensure a professional-grade setup every time.

• Replaces standard collapsible crush sleeves with a solid spacer
• Maintains consistent pinion bearing preload under high torque
• Precision machined shims for exact adjustment
• Fits Ford 7.5" and 8.8" differentials
• Manufacturer Part Number: SK CSF8.8
