If you're serious about off-roading or want to enhance your vehicle's traction during high-performance driving, the Yukon Grizzly Locker YGLF9-31-LB is a must-have upgrade. This mechanical positive-locking differential is designed specifically for Ford vehicles equipped with a 9" axle and 31 spline axles, making it an ideal choice for enthusiasts looking to tackle everything from rock crawling to drag racing.
The Grizzly Locker is engineered for durability and performance, featuring an advanced gear tooth design that maximizes traction. With this locker, you’ll get 100% power sent to both tires, ensuring that you can conquer tough terrains without losing momentum. The innovative design allows for disengagement while turning, which means you won’t have to compromise on handling when navigating tight corners.
The Yukon Grizzly Locker is compatible with a wide range of Ford models, including:
Many Ford F-150 owners have shared their experiences with the Grizzly Locker. One F-150 owner mentioned, "I installed the Grizzly Locker on my 1985 F-150, and it transformed my off-roading experience. The traction is incredible, and I can power through tough trails without any worries about losing grip." Another customer with a 1979 Ford Bronco said, "This locker made a huge difference in my Bronco's performance on the rocks. It’s tough, reliable, and I can't imagine going back to a standard differential."
Upgrade your Ford with the Yukon Grizzly Locker YGLF9-31-LB and experience the difference in traction and performance. Whether you're hitting the trails or the drag strip, this is the differential that can handle it all.
