I'm looking to regear my truck since it lacks the power and mileage I'd like... I have a question for any ford gurus out there, As of right now, I my truck is bone stock, with 31's and 3.31 gearing- have to romp on the gas to get moving/sucks to wheel with, I was wondering how much of a difference will bumping up to 3.73 - 4.11 gearing make? Would it be worth the investment? This truck is my DD and my weekend warrior. Any input or a point the right direction would be greatly appreciated. Sorry for the longish read
