Im running the 410's and 35" KM2's. My speedo is off about 5mph. You can get by with stock gears. I am putting 513's in before moab. If you are conserned about the speedo i would order an AEV Procal for about $125. You can fix the speedo and a lot of other cool stuff for a great price

As far as wheel'n goes, the 4.10 is fine. You will notice the negative difference when you are trying to climb hills at highway speeds. I ran 35"s and 4.10 for a while on my 07 X and will be running them again on my current rig.
If I had the extra cash, which I do not, I would love to regear to 4.88 just to get it back to stock.

The big question is do you have a manual or auto? I have a manual with 35's and 4.10's and it is fine, there is definitely a difference but not too much, and I lost about 1.5 mpg.
With an auto I think re-gearing is more necessary.

I had 3.07s and ran 33s for about 2 months, would NEVER do that again. Was with an XJ and the 4.0 engine. Was difficult just starting in 1st gear on an incline. I vote to re-gear.
