The Yukon electric selectable locker is a replacement OE-style unit for Ford 8.8-inch differentials with 34-spline shafts, specified for 2015 and up Ford 8.8" applications. Electronically actuated, it delivers full 100% lock-up on demand yet operates like an open differential when disengaged for streetability. The unit uses forged case construction and premium alloy internals for long-term service.
