Yukon Gear Grizzly Locker / Ford 9in w/ 35 Splines / For Use w/ Load Bolt Dropout

If you're looking to maximize traction for serious off-road adventures, rock crawling, or drag racing, the Yukon Gear Grizzly Locker is a robust mechanical differential designed for Ford 9-inch axles with 35-spline setups and load bolt dropout housings. This locker engages 100% of the available power to both rear wheels simultaneously, ensuring that neither tire spins out when you need grip the most. It's built for demanding conditions where standard differentials can't keep up.

What sets the Grizzly Locker apart is its patented internal design, featuring larger clutch teeth with 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 for added durability, and the entire unit is assembled in the USA. This attention to robust construction means you can rely on it when you're deep in the trail or pushing your vehicle to its limits.

This locker is a solid option for a wide range of classic Ford vehicles equipped with the appropriate axle setup, including models like the Ford Bronco, F-150, and Mustang from various years. While it locks both wheels for maximum traction, it still allows for disengagement when negotiating turns, making it more manageable on the street than some other locker types. Installation will require removing the differential cover and setting up the gears, so refer to the manufacturer's instructions for the full procedure.
