X2 on Jasper, although I only bought a 2.5 from them about 15 yrs ago. The first one ran great for about 20,000 miles. Then I drove into a small pond and threw a rod. I learned. The second lasted great, but I sold it. But they were easy to work with.
I rebuilt my own 4.0. So far so good.
1991 YJ, rebuilt 4.0L in spring 2009 at 234,000 miles, no lift yet, slightly offset wheels, 235/75/15 tires for now, rag top, sold the hard top. Over 35,000 miles on the rebuild and counting.
2006 Jeep Liberty. Nothing special, all stock.
