This is a four cylinder YJ and will be for a long time. I only plan on trail ride and going to the beach with it. So i want to stick with a easy swap, like an 8.25.
Perch moving is no problem becase i'm planning on doing a flip on both rears.
unless you already have an 8.25, i would look for an explorer 8.8. Much stronger, about the same amount of work, and you get disk brakes. but you have to buy wheel spacers to get the width to match.
