This is the best choice for an front axle installation. Great improvment in offroad tractions combined with daily road use. This is what I call value for money.

      Brj, this Detroit Locker is for the front only Dana 30 application which was factory for the WJ. You should have from the factory 27 spline shafts. The best way to check what gears you have is to open the case and count the teeth.
