Yukon Gear Grizzly Locker For GM 8.5in & 8.6in / 30 Spline / 2.73+
$1,133.89
Everything about the Yukon Grizzly Locker is hardcore, its casing and gears, its advanced gear tooth design, and its impact on traction and performance. The Yukon Grizzly Locker is a mechanical positive-locking differential that’s engineered for rock crawling, serious trail running, off-road racing, and drag racing. The unit provides 100% power to both tires, while still allowing for disengagement while negotiating turns. The Yukon Grizzly Locker is a patented design that features innovations that make it tougher than the competition. Its inner clutch teeth have a larger radius at the base, which offers up to 350% greater strength versus back-cut designs. The Grizzly Locker’s larger teeth also resist breakage caused by shock-loading or catastrophic axle failure. It’s a serious piece of mechanical engineering for serious driving conditions.
The Yukon Grizzly Locker is the ultimate in mechanical locking differentials for street; off-road; and drag racing. Grizzly Lockers provide 100% power to both tires; while still allowing for disengagement while negotiating turns.

The Yukon Gear & Axle Grizzly Locker is a high-performance, mechanically locking differential designed for serious off-road enthusiasts, trail runners, rock crawlers, and drag racers. Engineered with advanced gear tooth design and a patented internal mechanism, this locker ensures maximum traction by providing 100% power to both wheels, even during challenging turns. The robust construction and innovative design make it an ideal upgrade for GM 8.5-inch and 8.6-inch differentials with 30 spline axles. Its durable 8620 internals and larger internal clutch teeth with a greater radius at the base deliver up to 350% increased strength compared to back-cut designs, significantly resisting breakage from shock-loading or catastrophic axle failures. Whether navigating rugged terrain or pushing the limits on the strip, the Yukon Grizzly Locker offers reliable, high-impact performance. The large bearing journal design, measuring 1.78 inches, necessitates heavy-duty bearings (LM102949/LM102911) for proper installation. Assembled in the USA, this locker is built for durability and long-lasting performance, fitting gear ratios of 2.73 and higher. Its internal design reduces common locker failures, providing peace of mind during intense off-road adventures or racing applications. This unit is not compatible with CARB-registered vehicles but is suitable for street, off-road, and racing environments where maximum traction and strength are required.
Features:
- Patented internal design reduces common locker failures
