The Yukon Spartan Diff Locker has been designed to provide the Dana 44 with better traction properties. This differential locker features a 30-tooth spline, and includes a heavy-duty cross pin shaft.
This particular design eliminates the need for thrust washers, and employs a spring and pin design that provides for an easy installation. Additionally the Spartan Diff Locker replaces the spiders in a standard case, and makes for a cost effective means of acquiring more traction.
