Everything about the Yukon Grizzly Locker is hardcore, its casing and gears, its advanced gear tooth design, and its impact on traction and performance. The Yukon Grizzly Locker is a mechanical positive-locking differential that’s 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 while negotiating turns. The Yukon Grizzly Locker is a patented design that features innovations that make it tougher than the competition. Its inner clutch teeth have a larger radius at the base, which offers up to 350% greater strength versus back-cut designs. The Grizzly Locker’s larger teeth also resist breakage caused by shock-loading or catastrophic axle failure. It’s a serious piece of mechanical engineering for serious driving conditions.
