Im pretty sure of the answer, but was wanting some guru insight real quick.....

So I have a 3.5 RK x-factor....and offroad bumpers on my 2011 JKU....

So if i was to buy a 2014 Rubi, will these things just swap over to it? I didnt think anything had really changed other then the motor deal.

 

I was on the RK website it says 07 to present.....guess that pretty much answers that....!

 

The only area with any issues is really the winch mounting plate. They have the stupid vacuum pump on the new engine instead of using the engine for the vacuum. I just cut off the bracket and moved the pump to make mine from an 09 work on my 13.

 

I'm thinking most if not all of your items should swap over. I too am in the same boat, going from an '11 JKUR to a '14 JKUR. I have a 2.5" lift and some other items I want to swap over.

As for the front bumper, you could move the vacuum pump back or relocate it. I think Teraflex has a relocation bracket for that, to move it up by the brake booster/master cylinder.
