High Performance Automatic Locker
If you use your Super Duty for heavy applications like towing, off-roading or trailblazing, you need a diff lock that's up to the task. Yukon's Grizzly Locker features a chromium alloy forged case and 8620 internals, as well as an internal locking mechanism for maximum strength. On or off the street, this premium automatic locker will deliver 100% power to both wheels and allow for disengagement for turning. Once you take a drive with Yukon's Grizzly Locker installed, you'll understand why it's been endorsed by NASCAR and chosen by Ultra-4 Off-Road Racing as their diff lock of choice.
