Yukon Gear Grizzly Locker For Ford 9in w/ 31 Spline Axles / Racing Design

The Yukon Grizzly Locker features an advanced gear tooth design with inner clutch teeth that have a larger radius at the base. This patented design offers up to 350% greater strength compared to back-cut designs, helping to resist breakage from shock-loading or catastrophic axle failure. This mechanical positive-locking differential is built for demanding conditions like rock crawling, serious trail running, off-road racing, and drag racing.

Constructed with 8620 internals for added strength, the Grizzly Locker ensures 100% power is sent to both tires simultaneously. This aggressive design is specifically intended for racing applications and provides the ultimate in traction when you need it most. While it locks both wheels for maximum grip, it still allows for disengagement when negotiating turns, making it a serious piece of mechanical engineering for those who push their vehicles to the limit.

This locker fits a wide range of Ford 9-inch rears with 31-spline axles, including popular models like the Ford Bronco, F-100, and Mustang from various years. It's assembled in the USA and is a robust option for anyone looking to significantly improve their vehicle's drivetrain performance in competitive or extreme off-road environments.
