Im getting ready to pull the trigger on a new 2014 Unlimited Rubicon X and was wanting to know if anyone knows if there is and major changes to the 2015 such as motor or tranny changes. I have heard all the rumors but was looking for facts. Also would u go with 410 or 456 gears ? Im going to run 35 inch mtz tires. ANY help would be great It is an Automatic tranny also. Thanks

 

4:10s should be adequate but 4:56s are a lot of fun with that extra power to the wheels if your going from a cost perspective, it costs lest to buy it already with 4:10s then to have it done by someone else

 

The jeep currently has 373s it was ordered that way for some reason but the dealer agreed to put 410s or 456s in for me if i trade them the factory tires and wheels which i wont be using anyway .

 

I actually just talked to dealer in the phone and answered part of my own question they are currently ordering 2015 and no changes except color for 15 he said major change will be for 17 which i expected. Still curious about the gears though witch to go with and witch would take it back to the factory power feeling? I just sold my 2012 power wagon and it had 456 gears with 33 inch tires and it was great but probably a little to low of gear and it liked fuel . im thinking with the v6 and 35s 456 might be the way to go in the rubi.

 

That's an awesome trade off!!! I would go 4.56 that way if u decide to go 37's you're already to go!!

 

That was my thought also i doubt that i go 37s but you never know do you think that is a good gear for the 35s or will it be like my power wagon and be too low ? Thanks for the input guys.

 

You'll be happy with either but if it was me, and like 99% of the rest of this forum, I wouldn't get in there and throw 410s in. I would go with the 456. Might cost you a little mpg but it's worth it. The only reason I would have 410 is if it came stock. Then I wouldn't change at all.
