Ok so i purchased my nissan titan used with 8k about a year ago and got a screaming deal. Ideally i wanted the tow package with the bigger mirrors. Come to find out after buying truck i realize the tow package also includes the better gear ratio. So to make a long story short.. Can i go to the dealership to buy the kit or do i have to go aftermarket. IF so where do i find those gears aftermarket? I have done a little looking around and have not found much of anything. Does anyone have any recommendations on what i should do?
