Front and Rear diff information

[Magoogle]

Hey fello expy owners.

Im looking to install a simple 3in lift on my 04. so 35" tires will be going on. Now I will still be needing to tow my 29ft car hauler so need to try and keep the gears as close to 3.73 as I can get. So either 4.10 or 4.27 area.

Anyone know what size the carriers are? Im trying to shop around on 4wheelparts.com but when I put in my truck I get stuff for Dana 44's, Ford 8.8in, GM 8.5's and all other kinda axles. What are our differentials? Anyone provide me a link to some? Also would you guys recommend the 4.10 or should I go a little higher? I would like to try and maintain my current fuel eco as close as possible, when not towing but I would also like to have a little more power towing.

4.56 for 35s.... 4.88s for anything bigger.... and 8.8 reverse gears are needed for the front and 9.75 for the rear... if I remember correctly was that way when i got them into my 97 F150...
