do you know what gears you have now....i think there 2.73 and if so yes you will see a big difference....i went from 2.73's to 3.42's and i felt a good difference and my gas milage got better.....it all depends on what you drive more...city or highway...i do about both equal so for somereason i get better gas milage with my 3.42's. and since you have an auto probably wouldnt go with the 4.11's
