I would call a dealership parts department with your Vin. Hopefully they can tell you, but if not, you may be able to at least use the part number they give you and research online.

My best guess would be that the difference is between gas and diesel or between 3.6 and 2.0. Might be a Rubicon/sport thing too.

Get your clutch pack from Center Force and tell them what Jeep/engine you have. They'll set you right.
