Yukon Gear Grizzly Locker For Ford 9in w/ 35 Spline Axles

Yukon Gear & Axle is known for building tough drivetrain components, and their Grizzly Locker is a prime example of that commitment. If you're looking to maximize traction for serious off-road adventures, rock crawling, or even drag racing, this mechanical locker is designed to handle extreme conditions. It works by sending 100% of the available power to both rear wheels simultaneously, ensuring that neither tire spins out when one loses grip.

What sets the Grizzly Locker apart is its robust internal design. It features a patented system with inner clutch teeth that have a larger radius at the base. This design offers significantly greater strength compared to other types of lockers, helping to resist breakage even under heavy shock loads or in the event of an axle failure. The internals are made from 8620 steel, known for its durability, and the entire unit is assembled in the USA. This locker fits a wide range of Ford 9-inch rear ends with 35-spline axles, including popular models like the Ford Bronco (1966-1986), Ford F-150 (1975-1987), and Ford Mustang (1965-1973).

While this locker provides incredible traction, it's important to remember it's a mechanical unit. It will lock both wheels together, which means you'll experience some tire scrub and turning resistance on pavement. However, for off-road use or situations where maximum grip is essential, the benefits far outweigh this characteristic. Installation involves setting up the differential gears, so it's a job best suited for someone with experience or a professional mechanic.
