Yukon Gear Grizzly Locker / Dana 50 / 30 Spline

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 significantly improve traction for serious off-road adventures, rock crawling, or even drag racing, this mechanical locker is designed to handle extreme conditions. It's engineered to provide 100% power to both rear wheels simultaneously, ensuring you maintain momentum when one tire loses grip.

What sets the Grizzly Locker apart is its robust internal design. The casing and gears are built for durability, and the advanced gear tooth design features a larger radius at the base. This unique feature offers up to 350% greater strength compared to other designs, helping to resist breakage from shock loads or catastrophic axle failures. The internals are made from 8620 material for added strength, and the unit is assembled in the USA. While it locks the differential for maximum traction, it's designed to allow for disengagement when negotiating turns, making it more manageable on the street than some other locker types.

This Grizzly Locker is specifically designed to fit Dana 50 axles with 30 splines. It's a serious piece of mechanical engineering for those who push their vehicles hard. Keep in mind that installing a locker often requires specialized tools and knowledge, and it's recommended to consult the manufacturer's installation instructions or a professional mechanic for proper setup.
