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 thats engineered for rock crawling, serious trail running, off-road racing, and drag racing.
The unit provides 100 percent 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 percent greater strength versus back-cut designs. The Grizzly Lockers larger teeth also resist breakage caused by shock-loading or catastrophic axle failure.
Its a serious piece of mechanical engineering for serious driving conditions. The Yukon Grizzly Locker is the ultimate in mechanical locking differentials for street, off-road, and drag racing.
Grizzly Lockers provide 100 percent power to both tires, while still allowing for disengagement while negotiating turns.
