I was not sure about getting 3.73 or 4.10's but after reading the tech article on here I am sure about the 4.10's. I'm sure alot of people on here have the 4.10's so I'm just wondering where the cheapest place is to buy them online? Also I'm still a little concerned about the gas mileage I drive about 20 miles freeway each day for work and I've heard the only real concern for gas mileage decrese is on highway driving can anybody enlighten me on how bad it will drop?
