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.
Fits AAM 11.5'' with 38 spline axles. Grizzly Lockers are a mechanical locking differential designed for off-road and racing use. Patented design reduces common locker failures.
Factory spindles will need to be bored out with tool part number YT H32 in order to accept the 38 spline axles this locker takes.
11.5AAM, 38spl, GM & DODGE GRIZZLY LOCKER
