"Took about 4 mins to install on my 2012 Ram for 35 inch tires. It has def helped my tranny to adjust for larger tires. The only gripe I have is the price could be a little cheaper considering that it doesnt do anything other than adjust gears/tires/codes. Overall great for 2012s as it is our only choice right now." —Douglas M from Clarksville , TN bought a Hypertech Speedometer Calibrator for a 2012 Dodge Ram.
"easy to use and work perfectly. derfinately measure your tire, dont trust the sells sheet about size." —John K from Victoria, TX bought a Hypertech Speedometer Calibrator for a 2012 Dodge Ram, 6.7L Cummins.
