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.

Complete Carrier Replacement

The Yukon Grizzly Locker is your all-in-one differential solution, replacing your diff carrier assembly entirely and providing improved durability. This speed-sensing automatic locker is designed to handle whatever you throw at it -- extreme off-roading, towing, and street use included!

One-Year Warranty

Yukon is so confident in the performance of this automatic locker that they back it with a one-year limited warranty against manufacturer defects.

Fitment: 10.5/10.25 Differentials
