Yukon Gear & Axle Zip Locker Dana Spline Up Differential

The Yukon Gear & Axle Zip Locker is an air-actuated selectable locking differential for Dana axles. It gives you open-differential manners for daily driving and a fully locked axle when you need maximum traction off-road. Because it is a spline-up design, it is also sold as a Dana Spline locker or selectable air locker.

Key Features:

• Selectable operation: Run the axle open for normal driving, then engage the lock on demand for full traction.
• Air-actuated design: Uses an onboard air supply to engage and disengage the locking mechanism.
• Spline-up design: Built to use the stronger axle shaft spline count of the Dana axle it is made for.
• Positive lock: Both axle shafts turn together when engaged, which helps in low-traction, rock-crawling and uneven terrain.
• Heavy-duty construction: Made to handle the stress of off-road use, larger tires and higher-horsepower builds.

Yukon Gear & Axle is a well-known name in aftermarket ring and pinion gears, differentials, axles and drivetrain components for 4x4, off-road and performance vehicles. The Zip Locker is a good choice for trail rigs, rock crawlers and work trucks that need on-demand traction without giving up on-road manners.
