I also read previous reviews that mentioned how nice it was to have two crush sleeves. The kit i received had zero crush sleeves. It was very frustrating when in the middle of the rebuild just to find out i'm missing parts. perhaps my fault for opening the desertcart box when i needed it rather than once i received it. Had to order the parts from a local shop. my kit came with everything else in the pictures. ## Features - This kit uses Timken (or equivalent quality) bearings and races - Contains All Necessary Parts for Installation - Designed for Specific Differential Application - Yukon's Master Overhaul kits are the most comprehensive and complete kits on the market ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003LU108C | | Best Sellers Rank | #33,270 in Automotive ( See Top 100 in Automotive ) #3 in Automotive Replacement Differential Assembly Kits | | Brand | Yukon Gear & Axle | | Customer Reviews | 4.5 4.5 out of 5 stars (1,410) | | Date First Available | May 11, 2010 | | Is Discontinued By Manufacturer | Yes | | Item Weight | 6.7 pounds | | Item model number | YK GM12T | | Manufacturer | Yukon Gear & Axle | | Manufacturer Part Number | YK GM12T | | Model | Yukon Gear & Axle (YK GM12T) 12-Bolt Master Overhaul Kit for GM Truck | | OEM Part Number | YKGM12T | ## Images ![Yukon Master Overhaul kit for the GM 12 Bolt Truck Differential - Image 1](https://m.media-amazon.com/images/I/711AHrXOpjL.jpg) ![Yukon Master Overhaul kit for the GM 12 Bolt Truck Differential - Image 2](https://m.media-amazon.com/images/I/71erG4KkgoL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐ Damaged *by D***N on February 14, 2026* Received opened , used , greasy and missing parts ### ⭐⭐ Missing crush sleeve *by O***E on August 11, 2020* I see in the picture that two crush sleeves should be included in this kit.
