Yukon Gear Crush Sleeve Eliminator Kit For GM 10.5in 14 Bolt Truck

Yukon Gear SK CSGM14T Crush Sleeve Eliminator Kit for GM 10.5in 14-Bolt Rear Differential

The SK CSGM14T from Yukon Gear is a solid crush sleeve eliminator kit designed for the GM 10.5in 14-bolt full-floating rear differential. Unlike a standard crush sleeve that compresses during assembly, the SK CSGM14T replaces the crush sleeve with a solid spacer combined with precision shims, allowing the installer to dial in exact pinion bearing preload repeatedly without the need for a new crush sleeve on every rebuild. This is the preferred method for professional builders and performance applications where the differential will be serviced or adjusted more than once.

Features and Benefits

• Solid spacer replaces the factory crush sleeve for repeatable, precise pinion preload settings
• Adjustable shimming allows the installer to fine-tune preload without replacing the spacer
• Eliminates the risk of over-crushing during pinion nut installation
• Preferred for off-road, towing, and heavy-duty performance builds on GM 14-bolt axles
• Allows differential to be re-opened and re-sealed without requiring a new crush sleeve
• Engineered specifically for the GM 10.5in 14-bolt full-floating rear axle
• Manufactured to Yukon Gear quality standards for long service life

Frequently Asked Questions

• What differential does SK CSGM14T fit? The SK CSGM14T fits the GM 10.5in 14-bolt full-floating rear differential used in Chevrolet and GMC 3/4-ton and 1-ton trucks, vans, and Suburbans from 1973 through approximately 2010.
• Does SK CSGM14T include a pinion seal? No. The SK CSGM14T is a crush sleeve eliminator kit for setting pinion bearing preload. A pinion seal is not included but should be replaced during any pinion service.
• What is the benefit of a crush sleeve eliminator over a standard crush sleeve? A standard crush sleeve is a one-time-use component that deforms during installation to set preload. The SK CSGM14T solid spacer with shims allows you to set and reset preload precisely without replacing the spacer, which is especially valuable for builds that will be serviced or adjusted multiple times.
• Is SK CSGM14T required for a ring and pinion swap? No, but it is recommended for performance and off-road builds. The SK CSGM14T provides more consistent and repeatable preload than the OEM crush sleeve, which is beneficial during initial setup and any future adjustments.
• Does SK CSGM14T work with all GM 14-bolt pinions? The SK CSGM14T is designed for the standard GM 10.5in 14-bolt full-floating application. Always verify your specific axle variant before installation.
• Can SK CSGM14T be reused? Yes. The solid spacer in the SK CSGM14T can be reused when the differential is opened for service or gear changes, which is one of the primary advantages over a standard crush sleeve.
• Is this kit covered under the Magnuson-Moss Warranty Act? Yes. As a consumer product sold in the United States, the SK CSGM14T is subject to the provisions of the Magnuson-Moss Warranty Act. Yukon Gear provides a limited warranty against defects in materials and workmanship. Installation of aftermarket differential components does not void your vehicle manufacturer's warranty on unrelated systems under federal law.
• Does SK CSGM14T fit the GM 10.5in semi-float axle? No. The SK CSGM14T is designed for the full-floating 14-bolt axle. The semi-float variant uses different dimensions and requires a different kit.

Installation Instructions

1. Safely raise and support the vehicle. Drain differential fluid from the GM 14-bolt housing.
2. Remove the pinion nut and flange from the pinion shaft.
3. Remove the pinion seal. Remove the pinion shaft from the housing, noting the shim arrangement behind the rear pinion bearing.
4. Remove the old crush sleeve from the pinion shaft area.
5. Clean all components. Inspect pinion bearings and races for wear. Replace as needed.
6. Install the solid spacer from the SK CSGM14T onto the pinion shaft in place of the crush sleeve.
7. Add shims from the SK CSGM14T kit as needed to achieve the correct pinion bearing preload when the pinion nut is torqued.
8. Install a new pinion seal. Reinstall the pinion flange and torque the pinion nut to specification while frequently checking rotating torque with an inch-pound torque wrench until the specified preload is achieved.
9. If preload is too low, add shims. If too high, remove shims. Adjust and repeat until preload is within specification.
10. Reinstall the differential cover with new gasket or RTV. Fill with correct differential fluid to the proper level. Lower vehicle.
