Finally bought a new '08 F150. My '98 will live out the rest of it's years with my bro in Colorado. I'm looking for a limited slip differential for this new '08, yes, can you believe a FORD truck without L/S? I think Martha Stewart's designing trucks now, but I can't prove it. I think I've found a unit on eBay, but can't be positive, as they didn't provide enough info to cross reference. Anyone know what the E7TW means, or if this differential will work in an '08?

 

Your new truck should have a 9.75 or something like that. I remember the newer trucks I have seen had a huge rear axle, and IIRC they dropped the 8.8 completely when they dropped the 4.6l.
