Yukon Gear & Axle Grizzly Locker Ford Spline Differential

The Yukon Gear & Axle Grizzly Locker is a high-performance mechanical positive-locking differential (also called a locking differential or locker) for Ford applications. It is built for rock crawling, trail running, off-road racing and drag racing. It sends 100% of the power to both tires. It can still disengage when you go around a corner.

Key Features:

• Mechanical locking design that delivers full power to both wheels for maximum traction
• Disengages through turns, which allows controlled cornering
• Patented internal design that reduces common locker failures
• Inner clutch teeth with a larger base radius, which Yukon says gives up to 350% more strength than back-cut designs
• Larger teeth that resist breakage from shock-loading or axle failure
• 8620 high-strength steel internals for added durability
• Assembled and quality tested in the USA

The Grizzly Locker has been tested in off-road and drag racing competition. It is a heavy-duty traction upgrade for drivers who need more grip than an open or limited-slip differential gives them. Select the child item that matches your Ford axle and spline count.
