So what would you guys recommend for gears? I'm thinking either 3.90's or 4.10's, my truck is a DD and just about all my driving is in city but I still want to get at least decent highway gas mileage. Currently I have 3.42 gears and 29" tires and I'm thinking I'd go with the MT ET Street DR and they come in a 28" or 30" tire...I think I'd go with the 28". The cam I plan on going with is a 220/224, all other mods are in my sig.
