I have 2012 ram express hemi some reason i have the 3.55 rear axle gears instead of the other optional 3.73 gears. My buddy has the 2012 challenger rt with 3.92 gears i want more torque for faster times without comprimising top speed andwithout being ridiculous on mpg. 3.73 gears , 3.92 gears or the 4.10 gears
