Yukon Gear and Axle YK GM11.5-B Master Overhaul Kit GM/Dodge 11.5 in. Differential (4.375 in. Pinion Race)

The Yukon Gear and Axle YK GM11.5-B is a Master Overhaul Kit designed for the mid-2011 and later GM and Dodge 11.5-inch differential — specifically the updated design featuring a rear pinion bearing race outer diameter of 4.375 inches. (Note: the earlier pre-mid-2011 design used a 4.125-inch O.D. race; this kit is not compatible with that version.) Yukon offers more tailor-made differential rebuild kits than any other manufacturer in the industry, and each kit is the result of extensive research to ensure every necessary component is included for a complete, professional-quality installation.
