stock gear (4:73 I think) running 37's with auto trans. I find that evertime I drive I need to turn off overdrive (button). I feel like it just idles too low. Any ideas other than the simple solution of 5:13's

 

Two others. Supercharger or Hemi.


Seriously, with an auto, 3.73's/4.10's and 37's ??? Why would you consider anything at all before the gears ?

 

I thought all Rubi's had 4:10's, mine does.

 

Im confused....

 

You probably have stock 4.10's (No such thing as a 4.73) With an automatic, the only reasonable solution is 5.38's with 37's. (5.13's work well with an auto and 35's, 5.38's are more desirable with 37's)

Unless you are looking at a Hemi or Supercharging, that is your best option.
