I dont think they make 4.88's for the 7.5 I could be wrong though. If I was you I would find a 8.8" rear end you can find them pretty cheap. What size tire are you going to running also?

31s-35s.im into wheel well space and ill probably buy whatever i can find a deal on.the 4.88s would explain why i cant find em on ebay.4.56s it is.its all up in the air for now.i hate the 3.73s now, so anything is an improvement. 4.56? gear swap first then maybe a 3"or 5.5"spindle lift,then tires. if for some reason i dont lift it at least ill have some better gears.

dont buy gears off ebay....you DO NOT want cheap chinese made junk.

What are you plans for the truck? 33's and 4.56's on a 4cyl should be about just right.

I suggest finding a junkyard 8.8" w/ 4.10s, and go from there. I don't think i've seen 4.88's for a 7.5".

Not all explorer rearends have disk brakes some have drum and if you dont feel like putting that little extra effort into your work then just go with a ranger 8.8 it can handle atleast 33's and 35's from what i hear
