dang it. Well do you think 295/70/17 (33.3x11.6/17) would be okay with mine?

I have an 11 with 3.73 Auto and went with 35s. They are 33.75 on the ground with 30 psi. I was pretty worried about the unknown performance lose before I lifted and put them on. Obviously the charts will give you the best gear/tire performance, but there are too many other variables involved when it comes to each individuals expectation or lack of. I am happy with the set up I went with and the power lose has been minimal. I will probably re-gear in the future, it's just not in the top of my list like I thought it would be. Just my 2 cents.

numbers and charts are the official, "right", information to go off of but for me with my 321 gears, and 35s, the power loss was barely noticeable, and if you are afraid of being underpowered offroad, just drop it in 4low. 33 mts will give you a huge leg up off road even if you are a little undergeared. Again, this is just me.

Also keep in mind i have about 80hp on you (more torque also). If i were you, id say go for it. Regear after if you havvvvve to. I bet it wont be bad enough for you to have to right away, its not for me.

Do you have a sport, Sahara, rubicon, islander etc.. As previously stated, you can enter/ email Chrysler with VIN on their website, or count the revs while spinning a rear wheel...

There isn't a huge difference in horsepower in "normal" driving range between the two engines. The 3.6 has higher torque throughout but I would venture to say the biggest difference people feel is in the transmission(auto). I would be interested in seeing a comparison between the two engines, both manual at the wheel. sorry for getting off topic. I know people are going to kill me for this, but if you want to do it correctly you should regear.

Yea I think it will look really good too. It will mostly be a DD but I mud every now and then. No rock climbing in my future anyways considering I'm in Oklahoma

Love the look of yours! I also have a flame red. Do you have a 3.6L or 3.8L?
