Yukon Gear Grizzly Locker For Dana 60 / 4.56+ / 35 Spline

If you're tackling serious off-road challenges like rock crawling, trail running, or even drag racing, you need a differential that can handle extreme conditions. The Yukon Gear Grizzly Locker is built for those demanding situations, providing mechanical positive locking for 100% power to both tires. This means you get maximum traction when you need it most, whether you're climbing a steep incline or powering through a tough trail. It's designed to work with Dana 60 axles that have 35 spline shafts and a gear ratio of 4.56 or numerically lower.

What sets the Grizzly Locker apart is its robust internal design, featuring a patented system with larger clutch teeth that have a greater radius at the base. This construction offers significantly more strength compared to other designs, helping to resist breakage from shock loads or catastrophic axle failures. The internals are made from 8620 steel, known for its durability, and the entire unit is assembled in the USA. This locker allows for full engagement when you need maximum grip, but it also disengages while turning, making it manageable for street use or navigating tighter trails.

This locker fits a wide range of heavy-duty trucks and SUVs, including popular models like the Chevrolet C10 Pickup (1967-1972), Dodge D200 Pickup (1968-1974), and Ford F-250 (1973-1979). When installing, it's important to follow the manufacturer's instructions carefully, as differential work requires precision. You'll also need to ensure you have the correct gear oil and any other necessary installation components for a complete setup.
