I have a 2003 F-150 Supercrew King Ranch 4x4 with the 5.4L Triton and it has a 3 inch body lift with 35x12.50 mud tires. My truck still has the stock 3.73 gears in it and its alittle slow. So what gears should i get so that it will be not as slow but will still do good in the mud? And my dad and I were thinking of switching the gears ourselves, good idea or not?

Thanks,
Paul

I'd go with 4.56 gears. They should fit in both differentials without any major modifications. I'd definitely take it to a shop and get them to do the install. It's a complex install and requires proper tools to get the preloads right, or else you're new gears will chew themselves up in no time if they're not aligned just right. Yukon Gear & Axle has some good products and a wide selection. If you want to bite more $ for fuel you may be able to put in lower gears, but I believe the 4.56s would be your best bet for not only performance but mileage as well.
