If you’re serious about off-roading or just love pushing your rig to its limits, the Yukon Grizzly Locker is a game changer. This isn’t just another locker; it’s built like a tank and designed for those who take their driving seriously—whether you’re crawling over rocks, tearing up trails, or even hitting the drag strip. What sets the Grizzly apart is its mechanical positive-locking design that delivers 100% power to both tires, giving you that much-needed traction when you need it most. And don’t worry about turning corners; it lets you disengage smoothly so you can navigate without a hitch.
The engineering behind this locker is impressive, to say the least. Its patented design features an innovative gear tooth structure that’s tougher than what you’ll find on the competition. The inner clutch teeth have a larger radius at the base, which means it boasts up to 350% greater strength compared to those back-cut designs that are prone to failure. This means you can tackle tough terrains without constantly worrying about breakage from shock-loading or axle failures. It’s a solid piece of mechanical engineering, built for serious driving conditions.
- Fits: Dana Spicer 60 with 30 spline axles
- Ratios: 4.10 and down
- Internal Design: Patented to reduce common locker failures
- Material: Tough 8620 internals for added strength
- Assembled: Proudly made in the USA
When it comes to specs, here’s the lowdown:
- Axle Shaft Spline Quantity: 30
- Cover Bolt Quantity: 10
- Material: Steel
- Type: Locking
This locker fits a wide range of vehicles, making it a versatile choice for many. Whether you’re driving a classic Chevy C/K from the 60s, a Dodge Ram from the 90s, or even a Jeep Wagoneer, the Grizzly has you covered. Here are just a few of the models that can benefit from this beast:
Compatible Vehicles:
- Chevrolet C/K 10 (1967-1972)
- Dodge Ram 2500 (1994-2002)
- Ford F-250 (1954-1986)
- Jeep Wagoneer (1963-1976)
- And many more!
In short, if you’re looking for a locker that can handle the rough stuff and keep you moving forward, the Yukon Grizzly Locker is worth considering. It’s tough, reliable, and engineered for those who demand the best from their vehicles.
