Re: What rearend?
Just keep the 8.8. It has 31 spline axles, and is generally considered a good solid rearend. I have 32x11.5.15's on my stock rear now, and they're fine. You can beef up the rearend with an Eaton Positraction unit, 4.10 gears, and all new hardware. I'm going with those in mine shortly. After I read an article about the ford drivetrain in one of my 4x mags, I've totally scrapped the idea of a 9-inch. The call I made to Randy's Ring & Pinion was very helpful, their techs are friendly and knowledgable.
