The Yukon Gear Grizzly Locker is a mechanical positive-locking differential engineered for the most demanding off-road environments, including rock crawling, trail running, and racing. This patented design delivers 100% power to both tires for maximum traction while allowing the unit to disengage automatically during turns for improved drivability on the street.

Built for extreme durability, the Grizzly Locker features 8620 steel internal gears and an innovative clutch tooth design. The teeth are engineered with a larger radius at the base, providing up to 350% greater strength compared to traditional back-cut designs. This added material helps the locker resist catastrophic failure during shock-loading or axle breakage.
