I am considering changing my 2012 V6 (Automatic) 2.73 gears to 3.73. If I do this, do I need to buy anything else? I know I will have to recalibrate my speedometer and shift points. Is there anything else I need to buy? A drive shaft or something?

 

you should be ok with the stock driveshaft ...But u should get a tuner ..bama .mpt steeda cause you will need to change your shift points and speedo

 

Welcome to the forum, enjoy the gears...
