    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.
