Just to share a little... my '91 4.0 Explorer is printed in the latest edition of Truck Trend (Jan./Feb. '04) in the "Reader's Rides" section. I will gladly share more for those of you who are curious about performance parts and/or results or ideas to consider and things to avoid. I'm very curious about other Exps with similar mods, (headers, exhaust, ignition, suspension, etc.) please share...

I would like to know of any suggestions to add limited slip or streetable locker to my open 3.55 diff.
