        1 2010 Wrangler - CrnFed3035

        Welded together junk

        Bought this for a guy in our jeep club and the case is welded together, not like pictures and videos show, because of this the guy wouldn't even waste time to install it. Then customer service at Yukon was very rude.

      Does this work with factory axels? Will this work with the factory dana 30 axel shafts? I've seen 27 spline and 30 spline versions, both say for a 2014 jku. I'll be upgrading to 4.88 gears with this.

      • The Yukon Gear Zip Locker for Dana 30 with 27 Spline Axles 3.73 & Higher (07-17 Wrangler JK) works with the factory Dana 30 axles that have the 27 spline axles. You'll need to confirm that you have a 27 spline axle.
