It all depends on how you youse your car, and how you want to modify it.Greekstang said:Hello all,
I have a 2004 3.9 all stock, but the mufflers force 2 flowmasters. I want to change my gears and put in a posse traction. Help me please what is the best gear ratio for my car and brand?
are you planning a power adder? SC or turbo? If so stick with the 3.27s already in the car. and get a detroit locker. pick up an underdriver with your gear money.Greekstang said:I did look it up although I'm still confused. in all I want to gain some speed, and I want both rear tires to have power.
I drive the car mostly on the weekends and after work, i would say equal amount of time driving on the highway and local.
what do you guys think?
you don't gain any hp with a gear swap, or with a limited slip rear.Greekstang said:Thanks Kc, is there any hp advantage with the detroit locker? I dont have the money for a supercharger right now but it is in the plans.
should i go with the ford racing gears, if I decide to go with 3.73s, and if so whats the hp gain ?
Also changing the pullys sounds like a good idea.
I do appreciate your help man.
