How does the Grizzly Locker improve traction?

The Grizzly Locker is a mechanical locking differential that forces both rear wheels to rotate at the same speed. This ensures that 100% of the engine's power is sent to both tires, even if one tire has very little grip, significantly improving traction in off-road or slippery conditions.

What makes the Grizzly Locker's design stronger?

Its patented design features inner clutch teeth with a larger radius at the base. This design offers up to 350% greater strength compared to back-cut designs and helps resist breakage from shock-loading or catastrophic axle failure.

What else might I need to install this locker?

Installation typically requires a differential rebuild kit, which includes bearings, seals, and shims. Heavy-duty bearings are often recommended for this application, and you'll need to set gear backlash and bearing preloads correctly. Always refer to the manufacturer's installation instructions for a complete list of requirements.

Product Details

This is the Yukon Gear Grizzly Locker, a mechanical locking differential designed for serious off-road use, rock crawling, and even drag racing. It's built to fit Ford 8-inch rear axles that use 28-spline axleshafts. If you're looking to maximize traction in challenging conditions, this locker ensures that both rear wheels receive 100% of the available power, which is crucial when you're navigating tough terrain or need maximum grip off the line. It's engineered to allow for disengagement when you're turning, so it doesn't fight you on the street or in slower corners.

What sets the Grizzly Locker apart is its robust internal design. The casing and gears are built tough, and the patented gear tooth design features a larger radius at the base. This design offers significantly greater strength compared to other types, helping to resist breakage from sudden shock loads or even catastrophic axle failures. The internals are made from 8620 steel, known for its durability, and the unit is assembled in the USA. This attention to detail in its construction means it's ready for demanding driving conditions.

This locker is a substantial upgrade for vehicles like the Ford Mustang, Falcon, or Bronco (early models) equipped with the Ford 8-inch rear end and 28-spline axles. While it provides maximum traction, remember that a locker will behave differently on pavement, especially during turns. For installation, you'll typically need to rebuild your differential, which involves setting gear backlash and bearing preloads. It's recommended to consult the manufacturer's installation guide for specific details and any required additional components like heavy-duty bearings, which are often recommended for this application.
