Yukon Gear & Axle Yukon Zip Locker for Dana 44, 30 Spline, 3.92 & Up, Fits Various Models - YZLD44-4-30

If you’re serious about off-roading, the Yukon Zip Locker is a game changer. This little beast gives you the flexibility to go from an open differential to a full 100% lockup on demand. That means when you're tackling tough trails or slippery surfaces, you can engage the locker and get the traction you need without skipping a beat.

Now, let’s talk specifics. This locker is designed to fit Dana Spicer 44 axles with 30 spline shafts, and it’s only compatible with gear ratios of 3.92 and up. So, if you've got a rig that fits the bill, you’re in for a treat. The forged case and 8620 internals mean this thing is built to last, even under the most rugged conditions. Plus, it works seamlessly with a variety of air delivery systems, making it pretty versatile for different setups.

What I really appreciate is that it’s assembled right here in the USA. There’s something about supporting local manufacturing that just feels good, doesn’t it?

Here are some quick specs if you’re curious:

  • Axle Shaft Spline Quantity: 30
  • Cover Bolt Quantity: 10
  • Material: Steel
  • Type: Locking

And if you’re wondering about fitment, this locker works with a wide range of vehicles. We’re talking classic Chevys like the Blazer and Suburban, various Dodge Rams, and even Ford Broncos from the 70s through the 90s. Not to mention it fits a bunch of Jeeps, from the CJ series to the Grand Wagoneer. If you’ve got a rig from this list, chances are you can upgrade it with the Yukon Zip Locker:

  • Chevrolet Blazer 1969-1974
  • Chevrolet C/K 10 1960-1980
  • Dodge Ram 1500 1994-2001
  • Ford Bronco 1971-1996
  • Jeep Wrangler 1997-2006

In short, if you’re looking to enhance your off-road adventures, the Yukon Zip Locker is a solid investment. It’s tough, reliable, and gives you the control you need when the going gets rough. Trust me, once you try it, you won't want to hit the trail without it.
