Description

It ensures 100% power is delivered to both tires, while still providing the ability to disengage for smoother negotiation of turns. Constructed with 8620 internals, this locker offers enhanced strength and durability. Its patented internal design incorporates innovations aimed at reducing common locker failures, including inner clutch teeth with a larger radius at the base for significantly greater strength compared to back-cut designs. These larger teeth are also more resistant to breakage from shock-loading or catastrophic axle failure. This unit is specifically designed to fit Ford 8.8" axles that utilize 31 spline axles. The product is Assembled in the USA, reflecting a commitment to quality manufacturing. The Yukon Grizzly locker is a robust piece of mechanical engineering suitable for the most serious driving conditions.
