What did you regear to?I used to be "oh the new 8-speed auto and 4.10 handle everything just fine" kind of person, I swear I will never regear because it is a totally waste of money.
Until I regear, there is a huge difference after regearing, in terms of how the Jeep handling acceleration and cruising, it is not just about 8th gear and mpg.
The Pentastar V6 has a notorious torque and HP curve, it started flat, and ended flat. It is actually not an optimal choice for an off-road vehicle. Regear helps a lot by giving some power in the lower end.
Besides, now I get 20 mpg on highway, yes 20 mpg with 37 and tons of gears (winch, hi-jack, roof rack, etc.) I hit myself everyday why not do this earlier.
