GM 10.5-Inch 14-Bolt Crush Sleeve Eliminator Kit

The Zumbrota Drivetrain SK CSGM14T is a crush sleeve eliminator kit specifically engineered for GM 10.5-inch 14-bolt full-floating rear differentials. This kit replaces the traditional crush sleeve with a solid spacer and shim kit, allowing for precise setting of pinion bearing preload. Each component is precision machined and tailored for the application, ensuring a reliable and proper fit for your differential setup. By utilizing a solid spacer, it removes the variable nature of crush sleeves, which can be prone to over-tightening or loosening over time, potentially leading to bearing damage. The included shim kit allows for fine-tuning of the bearing preload, crucial for the longevity and performance of the differential. While the provided evidence focuses on the product's function and compatibility with GM 10.5-inch 14-bolt trucks, it's important for users to consult with Zumbrota Drivetrain or a qualified mechanic to confirm specific year and model fitment, especially concerning the '88 and older variations, and any exclusions like the '84-'85 models mentioned in some listings.
