Regarding fenders: perrys are great and I got a great deal. Hannermann's is the only other that makes them for the Explorer that I found. Glassworks makes them for the Ranger series, and they should work, but no guarantees. There's still a lot of "fitment" tasks even with the perry's. Some of it may be due to my door bushings (I have one sagging and without a 1/2 gap I rub the glass fender when opening the door, but it doesn't happen on the other side, so I'm rigging a bracket with sheet metal screws to the inner tabs on the glass fender to poke it out just a little.
Regarding lift: Yes, 3" BL is in there. Only SUSPENSION lift is TT up front, AAL+2 in the rear (But its stiff so I may be removing one of the AALs....dont know yet). I'm hoping to get another inch from my TT, but I'm out of adjuster bolt length and my CV's are complaining a little already. That's why I need to cut more where it won't show behind the fender.
RE: Gears - still 3.73 LS, and haven't decided 4.56 or 4.88....with the gas prices, I'm thinking that maybe the 3.73 is good enough?

Seriously though, 4.56 will take me back to my stock ratios, so 4.88 should feel really powerful off road. Besides, I probably shouldn't be doing the 100+mph top speeds on swampers

, so I guess I don't need the upper end the 4.56 would allow. Right? So I guess I'm in the same position as you and looking for advice. I know the daily driver guys will say 4.56 and the hardcores will say 4.88 or 5.13.....I need a dd on 4.88s to give opinions.
