Yukon Gear Grizzly Locker For GM 8.5in & 8.6in / 30 Spline / 2.73+

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 GM 8.5” and 8.6” with 30 spline axles, 2.73 and up ratios. Grizzly Lockers are a mechanical locking differential designed for off-road and racing use. Patented design reduces common locker failures.
