scull20's Build of "Equinso Ocha" (aka White Devil)
Hope this is the proper way to reply, haven't quite figured out the forum. Thanks, I appreciate your comments. I'll have to look into the wheel spacers too. And do you mean my 3.8 will be more sluggish with 35's and stock 4.10s? From what I can tell by research, I'll probably want to re-gear sometime soon after I get 35s I guess anyway. Didn't realize the programmer would be that important. Thanks for the tips. May have to wait little longer and make sure I can purchase everything needed before making the jump in tires.

You're all good!
The 2007-2011 JKs came with the 3.8L V6, the 2012-Present JKs came with the 3.6L V6. The 3.6L V6 puts out more power and torque than the 3.8L. That will be one of the driving factors in determining the difference in performance when adding 35's. The stock 4.10s will be helpful in retaining some of that "pep", more so than 3.73s or 3.21. However, in general the addition of 35s will be more noticeable on a Jeep with the 3.8 vs 3.6. You can mitigate this through gearing, like you mentioned (this has been discussed IN DEPTH, give it a quick search on the forum, if you still need some guidance, let me know).
Some threads to look at:

Gearing for 35s

The programmer is not necessarily REQUIRED...but will be helpful for resetting your speedo and shift points (in an auto trans).
In my case, with the 3.6 and and 35s, I really didn't notice a terrible change in performance....but the extra power that the 3.6 has really helped in that regard. The major change I noticed what a reduction in braking performance. I'll end up getting the Dynatrac brake kit eventually.
There a plenty of people with 35s and the 3.8 out there, that I'm sure could comment on their thoughts of how the tires feel. In the end, I'm fairly confident you'll be happy with the 35s from a wheeling standpoint (I was!). You can hang onto you 4.10s for the time being and save for gears if need be to get some power back.
The wheel spacers are only a requirement of you run the stock wheels. If you have aftermarket wheels with less backspacing then you won't need them.
Hope it helps! Let me know if I can shed more light on anything.
