Yukon Gear Zip Locker For Model 35 w/ 27 Spline Axles / 3.54+

If you're looking to add serious off-road capability to your Jeep Cherokee, Wrangler, or American Motors vehicle, the Yukon Gear & Axle Zip Locker is a well-built option. This air-operated differential locker lets you switch from open differential performance for everyday driving to a full 100% lockup when you need maximum traction. This means you get the best of both worlds: on-road manners and off-road grip when you need it most.

Built for demanding conditions, the Zip Locker features a forged case and 8620 internal gears, giving it the strength to handle tough terrain. It's designed to work with a variety of air delivery systems and is specifically made for the AMC Model 35 axle with 27 spline axles and a gear ratio of 3.54 or numerically higher. This locker is assembled in the USA, ensuring a high standard of manufacturing. Installation involves setting up an air source and plumbing, so it's a job that requires careful attention to detail, but the result is a significant improvement in your vehicle's ability to navigate challenging surfaces.

When you need to crawl over rocks or power through mud, engaging the Zip Locker provides instant, full-time traction to both wheels. Disengage it, and you're back to a standard open differential for easier steering and better tire wear on pavement. This is a substantial upgrade for any off-road enthusiast looking for selectable traction.
