Yukon Gear Dropout Assembly for Ford 9in Diff w/Grizzly Locker 31 Spline w/4.11 Ratio (w/o Yoke)

What you get here is a complete, ready-to-install dropout assembly for your Ford 9-inch differential, featuring a Yukon Grizzly Locker and a 4.11 gear ratio with 31-spline axles. This unit is built by expert Yukon technicians and comes fully shimmed and set to the correct backlash, meaning you can bolt it into your housing, add the cover and fluid, and get back on the road. It’s designed to fit a wide range of classic Ford vehicles, including models like the Ford Bronco, F-150, and Mustang.

The heart of this assembly is its nodular iron case, which is stronger than standard cast iron. This improved rigidity helps reduce deflection under load, ensuring consistent gear contact for a longer service life and reliable performance. The inclusion of the Yukon Grizzly Locker is a significant upgrade, providing maximum traction by locking both axles together when needed, which is crucial for off-road adventures or demanding driving conditions. This assembly is specifically designed for the Ford 9-inch differential, a well-known and robust rearend used in many performance applications.

Keep in mind that this assembly does not include the driveshaft yoke, so you'll need to source that separately if you don't already have one. This is a serious piece of drivetrain hardware, built for those who need dependable traction and a robust differential for their Ford vehicle.
