i got 04 4x4 rcsb 5.7 hemi i just put a programer an some flows on it i can cut a 0 to 60 in the high 6s to low 7s i was wanting to cut that down just a lilbit what gears should i go with i know i have to change the front and rear out has any of yall done this about how much money am i looking at? an where would a good place to get them from off the internet

 

it all depends.. do you tow? wat size tires? a lot of highway or city driving?

 

For fastest times off the line and over-all performance 4.56s are the only way to go. And for best lock-up of both tires, you're gonna want a good aftermarket LSD.
Best places to purchase would be Air Ram, Moe's Performance, Randy's Ring & Pinion or 4 Wheel Parts.
I paid just under $1500 for rear & front gear sets, master install kit and Auburn Gear LSD and installation about 2 years ago. You are NOT going to want to attempt to install them yourself. To date, this is the only mod done to my truck that I paid someone else to do...

 

i dont really tow that much i drive in the city a good bit but alot of country roads to im got 17 inch rims with 265 75r
and thanks hammer il check them sites out
