I don't agree with everyone that says you'll lose 5th gear. I run mine in 5th all the time with 33s. Yes I may have to drop a gear if I'm going up a steep hill, its not as bad as everyone makes it out to be though and its not all the time that I have to drop a gear.
I will say this though, I'm sure I'll be amazed at the difference in power if/when I finally do gear down.....its something I look forward to.
Edit: I always love it when I can get the wind to my back, wind direction plays a huge roll with our Jeeps
