I would definately recommend re-gearing to 3.73 gears which you can easily get from the dealer and then just have it reprogramed for the larger tires and gears.

Do you know what gears it comes with the factory 06 3.7 commander and are you saying re-gear it beacuse of the power problem or becuase it will mess with the QT1 system what would you say the biggest tire i should run without re-gearing it

also do you still have your lift and tire set for sale? do you have a price?

The 3.7 Liter Commanders all come with 3.07 gears. I recommended for you to re-gear to the 3.73's found in the 4.7 Liter Commanders because of the power loss youll have running the 4 inch lift with that big of a tire. Lifting the Commander 4 inches and having that size tire will not effect the QT I system in any way other then the power loss of having the larger tires with the small v6 engine and 3.07 gearing.

With the EGR from superlift, you can fix your odometer and keep the ESP under control.
There is a guy on JU that has a WK with the 4'' superlift and 285's with no problems, he does wheel it hard. I believe he has the 307's
