Yukon ZIP Locker for Dana 44 Non-Rubicon Jeep Wrangler JK, 30-Spline
The Yukon ZIP Locker is a selectable, air-operated locking differential designed to deliver maximum traction on demand for non-Rubicon Jeep Wrangler JK models equipped with a Dana 44 axle and 30-spline shafts. When disengaged, the differential operates as an open unit for smooth street driving. When engaged, it provides a full mechanical lock to deliver superior 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 dual-purpose Jeeps that require controlled traction without sacrificing on-road drivability. Its selectable design allows the driver to engage the locker only when needed, making it a versatile and reliable upgrade for demanding terrain.
