Yukon Gear Grizzly Locker For Dana 60 / 4.10 & Down / 35 Spline

If you're looking to maximize traction for serious off-road adventures, drag racing, or demanding trail use, the Yukon Gear Grizzly Locker is a robust mechanical locking differential designed for Dana 60 axles with 35-spline shafts and 4.10 or numerically lower gear ratios. This locker engages automatically, sending 100% of available power to both wheels simultaneously, ensuring you maintain forward momentum even in challenging terrain. When you're back on the pavement or navigating tight turns, it disengages to allow for normal steering. This unit fits a wide range of vehicles, including classic Chevrolet C10 pickups, Dodge D200 series trucks, and Ford F-250 models from various years.

What sets the Grizzly Locker apart is its patented internal design, focusing on strength and reliability. It features 8620 internals for enhanced durability and a unique tooth design with a larger radius at the base. This advanced geometry offers significantly greater strength compared to standard back-cut designs, helping to resist breakage from shock loads or sudden axle failures. The larger teeth are built to withstand the rigors of aggressive driving, making it a solid choice for those who push their vehicles to the limit. It's assembled in the USA, reflecting a commitment to quality manufacturing.

When installing a locker like the Grizzly, it's important to note that this is a significant drivetrain modification. You'll need to ensure your Dana 60 axle is set up correctly with the appropriate gear ratio (4.10 and down) and 35-spline axle shafts. While the locker itself provides 100% lock-up, it's designed to work with your existing axle housing and components. Always refer to the manufacturer's installation instructions for detailed procedures and any specific tool requirements.
