Yukon ZIP Locker for Dana 44 Axles with 30-Spline Shafts, 3.73 Ratio and Down
The Yukon ZIP Locker is a selectable air-operated locking differential designed to deliver maximum traction on demand for Dana 44 axle applications equipped with 30-spline shafts and gear ratios of 3.73 and numerically lower. When disengaged, the differential operates like an open unit for smooth street manners. When engaged, it provides a full mechanical lock for superior traction in off-road and low-traction conditions.
Engineered for strength and reliability, the ZIP Locker is built from high-strength materials and is ideal for trail rigs, rock crawlers, and work vehicles that require controlled traction without sacrificing drivability. Its selectable design allows drivers to engage the locker only when needed, making it a versatile upgrade for mixed on-road and off-road use.
