P.S. This would be great for those who do not have the big tow package, It will increase your gear size allowing you to capture the full factory towing amount. Also, If you have bigger tires (like a lift), it will allow you to compensate for the tire size. Or for those that just want better acceleration, it will also help there as well. You will need to flash your computer though with a programmer since it will change up your speedometer.
