LOL - with the torque of a V8, I doubt you would have issues running 3.45 gears. You will be fine just like the 2.0T will have less issues than the 3.6L
With the 4xe, I have the same torque as the 392(and a couple hundred extra Lbs weight), but still have the 4.10's to help with larger tires. Since my tire/wheel combination is only 87Lbs and these are mini 37's, I don't feel any need to regear. Perhaps if I pulled a trailer often, but certainlly not for my normal, daily or weekend use. 8th gear is used slightly less on the highway and I notice it shifting to 7th more frequently than stock, but there is so much power in reserve, I've not had any problems. I really like these tires.

Any of you that were running heavy Nitto/Toyo, etc tires make the switch to these KO2 feel like you can tell the difference seat of pants?

Finally got my new KO2s on! Love them so far. No noticeable increase in road noise compared to the stock KO2s. They do feel a little more “squishy” when taking turns, but I guess that’s to be expected with more rubber. The tire shop had them at 42psi 😳 I’ve since taken them down to 34psi, which is obviously better, but plan to take more air out in the future. True mounted measurement is right at 35.25”.

Looking good. I agree. Barely can tell the difference from stock. Perfect size for me.

On my D range, they were pretty squirrely over 30 psi. I found 25-28 psi very comfortable and at most a 1 mpg drop from the original KO2s.

looks so good! The stance is perfect
Can't get a better stance than this IMO, not too high, not too low, just right! (do those steps have a quick disconnect for the trails, ? I assume they do)

Brad, tell me about those side steps!? Are they rock sliders? Is the lower step removable? How much do they drop from the door opening? Do they make an extension for the rear door too? Do you like them? Sorry for all the questions, but they look awesome!

Did anyone see the need for an adjustable track bar when they went with a Mopar 2" lift and 37" tires? I have that setup, and I believe I'm noticing some pull to the left when decelerating, and pull to the right when accelerating.... or the other way around. Basically, when you're giving it gas, it pulls one way, and when you let off, it goes the other way. Weird. Someone told me that was the trackbar not keeping the axles lined up from front to back, meaning one is pushed too far to the left or right, and the jeep can't push in a straight line because of that.

In a perfect world, you'd want an adjustable front and rear track bar. I have the MC 2.5" lift (F/R TB's are included) with the 37" KO2's at about 28PSI and haven't noticed any pull in either direction and the jeep tracks perfectly. It could also be the alignment though....

My rig... Brand new 37" x 12.5 BFG AT TA KO2s on 17 x 8.5 Alpha Delta wheen in light grey. Exactly the look I wanted. Still have some other additions to do, but I love the stance

, the height, and the capability.
BTW, I got them from Tirerack, and they were shipped within a week. Perfectly wrapped with the centering ring secured, and all 25 lugs included with the 5 tires/wheels.
I did the 2" mopar lift myself, took about 8-10 hours, all with hand tools and some muscle and a little patience. The book walks you throuhg it completely.
