Yukon Gear Zip Locker For Dana 44 w/ 30 Spline Axles / 3.73 & Down

When you're tackling tough off-road trails or need maximum traction for a specific situation, the Yukon Zip Locker for Dana 44 axles is designed to give you that on-demand control. This air-operated differential locker lets you switch from an open differential, which allows wheels to spin independently for easier turning, to a fully locked differential that forces both wheels to turn at the same speed. This is crucial for maintaining forward momentum when one wheel loses grip, like when you're climbing rocks or navigating deep mud.

Built for serious use, the Yukon Zip Locker features a forged case and 8620 internal components, materials chosen for their strength and durability under stress. It's designed to work with a variety of air delivery systems, giving you flexibility in your setup. This specific model is for Dana Spicer 44 axles that use 30 spline axles and are equipped with a 3.73 gear ratio or numerically lower (e.g., 4.10, 4.56, 4.88). It's a popular choice for many Chevrolet, Dodge, and Ford trucks and SUVs from the 1960s through the early 2000s, providing a significant upgrade in off-road capability.

Installation of a selectable locker like this involves opening up the differential housing, so it's a job that requires specialized tools and knowledge. You'll also need an air source, such as a compressor and tank, to operate the locker. When properly installed, the Yukon Zip Locker offers a substantial improvement in traction, allowing you to confidently tackle obstacles that would leave a standard open differential struggling.
