Yukon Gear Grizzly Locker For Dana 60 / 4.56+ / 30 Spline

Yukon Gear & Axle is known for building tough drivetrain components, and their Grizzly Locker is a prime example of that commitment. If you're looking to significantly improve traction for serious off-road adventures, rock crawling, or even drag racing, this mechanical locker is designed to handle extreme conditions. It's built for Dana 60 axles with 30 spline shafts and requires a gear ratio of 4.56 or lower.

What sets the Grizzly Locker apart is its hardcore construction and patented internal design. The casing and gears are built for durability, and the advanced gear tooth design offers up to 350% greater strength at the base compared to other designs. This means it's much more resistant to breakage from shock loads or catastrophic axle failures. This locker provides 100% power to both tires, ensuring maximum grip, but it still allows for disengagement when you're navigating turns, making it surprisingly manageable on the street. It's a serious piece of mechanical engineering for those who push their vehicles to the limit.

This locker fits a wide range of heavy-duty trucks and SUVs, including popular models like the 1967-1972 Chevrolet C10 Pickup, 1971-1980 Dodge B300, and 1981-1993 Dodge D250. Installation will involve setting up a new differential, which typically requires specialized tools and knowledge of gear setup. Make sure to consult the manufacturer's installation instructions for detailed guidance.
