The Yukon Grizzly Locker is a mechanical positive-locking differential built for rock crawling, trail running, off-road racing and drag racing. It provides 100% power to both tires yet allows disengagement while turning, using a patented internal design and larger inner clutch teeth for strength. This unit fits Dana Spicer 30 with 27 splines, requires 3.73 and up ratios, and uses 8620 internals; assembled in the USA.
