If you’re serious about off-roading or just tearing up the trails, the Yukon Grizzly Locker is a game changer. This isn’t just another locker; it’s built like a tank. The casing and gears are tough enough to handle whatever you throw at them, whether you’re rock crawling or racing. The Grizzly Locker is a mechanical positive-locking differential designed for the hardcore enthusiast. It delivers 100% power to both tires, which means you won't be left spinning in the mud while the other tire sits idle. Plus, it allows for disengagement during turns, so you won’t feel like you’re wrestling your vehicle every time you hit a corner.
What really sets this locker apart is its patented design. The inner clutch teeth have a larger radius at the base, making them up to 350% stronger than those back-cut designs you might see elsewhere. This is a big deal because it means you’re less likely to experience breakage from shock-loading or catastrophic axle failure. It’s the kind of mechanical engineering that gives you peace of mind when you’re pushing your rig to the limits.
Features:
- Designed to fit Ford 8.8" with 28 spline axles.
- Patented internal design minimizes common locker failures.
- Crafted with 8620 internals for that extra strength you need.
- Assembled right here in the USA.
Specifications:
- Axle Shaft Spline Quantity: 28
- Cover Bolt Quantity: 10
- Material: Steel
- Type: Locking
This locker fits a variety of vehicles, so whether you’re rolling in a Ford Crown Victoria from ’92 or a Lincoln Navigator from ’08, you’re covered. Here’s a quick list of some compatible models:
- Ford Crown Victoria (1992-2011)
- Ford Expedition (1997-2008)
- Ford F-150 (1997-2008)
- Ford F-250 (1997-1999)
- Ford Mustang (1979-2011)
- Lincoln Town Car (1981-2011)
- And many more!
So if you’re ready to take your driving experience to the next level, the Yukon Grizzly Locker is a solid investment. It’s tough, reliable, and built to handle the rough stuff. Trust me, once you’ve got this bad boy installed, you’ll wonder how you ever got by without it.
