I own a 2007 S331 truck and want to change the gear ratio from the stock 3:73 to 4:56.I do not race this truck but want more bottom end power.I have just recently added an electric fan kit, and the JDM super tune.
I am concerned with high RPM'S with every day driving in the city and or highway.
Has anyone done this modification, if so i would appreciate positive and or any negative feedback.
Regards,
Great White North
