Yukon Gear & Axle Grizzly Locker Dana Spline Down Differential

The Yukon Grizzly Locker is a mechanical locking differential (automatic locker) for street, off-road, trail, rock crawling and drag racing. It replaces an open or limited-slip carrier. It sends 100% of available power to both tires, and it can still disengage so the axle can turn corners.

Key Features:

• Mechanical positive-locking design that gives both wheels full drive power
• Disengages when turning, which helps with on-road manners
• Patented internal design that reduces common locker failures
• Inner clutch teeth with a larger base radius than back-cut designs. Yukon says this gives up to 350% more strength and better resistance to shock loading
• Hardened 8620 internals for added strength
• Forged case construction for heavy-duty use
• Assembled in the USA
• 1-year manufacturer warranty against defects

The Grizzly Locker is built for drivers who need dependable traction and durability from a Dana Spicer axle. Choose the child item that matches your axle's spline count and gear ratio range.
