Yukon Gear Grizzly Locker For GM 10.5in 14 Bolt Truck w/ 30 Spline Axles - YGLGM14T-30

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.

This unit installs into a bare factory open case. This unit does NOT use the factory thrust washers. Failure to remove the factory thrust washers will cause the unit to act improperly and can cause damage to the unit.
