Everything about the Yukon Grizzly Locker is robust, from its casing and gears to its advanced gear tooth design and its impact on traction and performance. The Yukon Grizzly Locker is a mechanical positive-locking differential engineered for rock crawling, serious trail running, off-road racing and drag racing. The unit provides 100% power to both tires while still allowing for disengagement when negotiating turns. The Yukon Grizzly Locker is a patented design featuring innovations that make it tougher than the competition. Its inner clutch teeth have a larger radius at the base, offering up to 350% greater strength compared to back-cut designs. The Grizzly Locker's larger teeth also resist breakage caused by shock-loading or catastrophic axle failure. It is a serious piece of mechanical engineering for demanding driving conditions.
