This was addressed a few month ago, and you do have to perform a slight modification to run it on the 2010s. I cant remember what the exact reason was but someone contacted rr and found the answer.
There are very few vehicles that can be defined as "made for offroad". Unfortunately, the Wrangler can definitely be defined as "made for offroad" by its inability to handle well on road
I installed this on my 2010. I remember it was a major pita for being a simple install. I believe I used different hardware or different bolts ( I did this in my buddies shop) so it went alright. Don't totally recall the deal but do remember it being more of a challenge that it should have. I have found many things that I have bought and done to my JK to require modification to some point. These are mass produced parts for the most part and things dont always go right.
I installed mine Saturday. I have a 2011. It was really easy but it took a while because I took my time. The cross member "bracket" is too long to put the plate flush. It will not install properly because the brackets are too long and pushing it away. Anyhow, I used a cutting wheel to take most of the excess bracket off and then grinding wheel to make it nice and flush with the cross member. Put some paint on it and good as new. Never done anything like this before and I am really proud of it!
As for the one hole you have to drill in the cross member it was simple as well. I tightened all the bolts (sway bar bolts and driver side cross member bolt) first. That made everything nice and tight. I used a transfer punch and drilled away. I cannot remember sizes though...anyhow looks great and really completes the bumper!
I installed one on a 2013. On mine at least there are brackets that hang down on each end of the cross-member that need to be cut flush and touch-up painted. It takes all of five minutes and is no big deal. In addition, you may need to drill a hole on the right side of the cross-member to run a bolt. Again, no big deal.
If you look at this pic, center top, you'll see an inverted triangular bracket, right next to the sway bar mount. It is the bottom one half inch of this bracket that needs to be cut flush on each side of the frame.
