The Yukon Gear Grizzly Locker for Ford 9-inch axles is a high-performance mechanical positive-locking differential designed to enhance traction and durability in demanding off-road conditions. Constructed with a robust casing and advanced gear tooth design, this locker delivers 100% power to both tires while allowing for disengagement during turns. Its patented design features larger radius inner clutch teeth, providing up to 350% greater strength compared to back-cut designs, and resisting breakage caused by shock-loading or catastrophic axle failure. Built for serious off-road use, it offers improved performance, strength, and reliability in challenging environments.
This locker is compatible with Ford 9-inch axles equipped with 31 spline axles and fits load bolt housings. It is suitable for applications such as rock crawling, trail running, off-road racing, and drag racing. Designed as a direct replacement, it provides a bolt-on upgrade for vehicles with the specified axle configuration. Installation involves replacing the existing differential with this unit, making it ideal for off-road enthusiasts seeking increased traction and durability in extreme driving conditions. The kit includes the locker assembly, ensuring a straightforward upgrade process.
