i have a new 2011 RT/Max. when i bought my car, i was specifically looking for a rear axle ratio of at least 3.06. i did minimal research and from dodge's website, i thought i was in business with mine because dodge shows 3.92 for my max on their 'build your own' webpage. i asked the salesman to confirm that my rear alxe was 3.06 or better and he told me that the webpage was wrong about the 3.92, but it did have the 3.06 so i was sold. after driving for a while, i just could feel from experience and also by what mph i could run 1st gear in to, they definitely werent 3.06. so i requested build sheet from chrystler and my rear axle is 2.6. i am so pissed. i have been lied to multiple times by the salesman, he could just tell me he doesnt know. so i basically want to upgrade my rear end. i am looking for suggestions. i do not no much about he chrystler rear ends...... i dont know what my options are, how much it will cost (roughly), and how hard/realistically will it be. i would like the 3.92's if possible, but i can settle at 3.06 at the worst. i just want the pick-up of a well geared car. i grew up in a grand national with 3.42's and i jsut love the get up and go of a well geared car. i would greatly appreciate any help on how i should go about doing all of this. where can i get these gears, is it as simple as changing internal gears, will the dealer get it, can i find them at aftermarket company, and where can i get the work done? these are my main questions and i greatly appreciate all help that any of you give me.

thanks!!!!
