Yukon ZIP Locker for Dana 44 Axles with 30-Spline Shafts, 3.92 Ratio and Up
The Yukon ZIP Locker is a selectable, air-operated locking differential designed to provide on-demand traction for Dana 44 axle applications equipped with 30-spline shafts and gear ratios of 3.92 and numerically higher. When disengaged, the differential operates like an open unit for smooth street manners. When engaged, it delivers a full mechanical lock for maximum traction in off-road and low-traction conditions.
Built from high-strength materials and engineered for durability, the ZIP Locker is ideal for trail rigs, rock crawlers, and mixed-use vehicles that require controlled traction without sacrificing drivability. Its selectable design allows the driver to engage the locker only when needed, making it a versatile upgrade for demanding terrain.
