Okay, I just picked up some sensatracks for a 1995 2wd Ford explorer. They are 5" longer and offer 3" of more travel vs. the stock cherokee shocks. All I need to do is swap out the bar pins(or cut open the explorers) and then swap out the bushings and I am good to go. Sierra, I know you wern't crazy about the sensatracks, but I have always heard good things about them for the most part. I would say whichever shocks I choose someone will have something bad to say most likely.
I am staying stock on the fronts for now. I might get a extender for them at autozone for $5.99 jsut to be safe.
