My apologies for terminology. Yes, its a 3.55 Dana 35c Limited Slip, originally equipped with the Police Group.
As I prepare to sell this, I was simply trying to help determine value. This Jeep has been a blast, especially in the winter, but it is going to give way to something sportier for at least three seasons.
For the curious, below is the full build information that I documented years ago when I purchased this XJ. Some features stumped my lifelong Jeep dealer, so this is an uncommon fleet vehicle.
