My Rockhard engine/transmission skidplate did not fit correctly on my 2010. I had only 1.5 mm clearance to the right side catalytic converter and also contact at the cross-over. I had to notch out the skid plate on the right side to clear the right catalytic converter and I had to add 1" of shims to the rear of the skid plate to allow clearance to the exhaust cross-over.
When I ordered the skid plate, I "assumed" it would fit, as the website states "2007-Up". It did not properly fit my 2010 JK, built in May 2010.
The additional small plate on the left side which attaches to the Rockhard skid plate and the left frame rail, is totaly rearward of the left side catalytic converter, so I do not believe it provides protection to the left side catalytic converter as advertised:
Jeep JK Wrangler
Oil Pan, Transmission & Dual Catalytic Converter Skid Plate
Rock Hard 4x4 Parts JK Oil Pan, Transmission and Dual Catalytic Converter Skid Plate fasten to the frame in front of both motor mounts and at the main crossover in the rear for maximum protection. An extension on the left-hand side protects the normally exposed converter which would be a very expensive fix if damaged. Also, to make oil changes easy and to minimize clean-up, this skid plate comes complete with a splash shielded oil pan drain plug access hole. All bolts at the frame crossover are replaced with tapered bolt head protectors to allow rocks to slide across them with ease and still allow you to get a socket on the bolt heads for removal. Our tests have shown stock drivelines to clear this skid at 40" of flex.
The OEM factory transfercase skid plate did protect catalytic converters. I just do not understand how the Rockhard skid plate protects the left catalytic converter. If it is damaged, it will be a very expensive fix, as stated above. This plate need to be about 9" forward, at least for my 2010 JK.
I guess I am a little disappointed in the Rockhard engine / transmission skid plate product. Maybe Chrysler L.C.C. made a design change to the exhaust system, but the website lead me to belive the skid plate would fit my 2010 JK. I had to "make it fit". I am not happy about that, but that is how I feel about my Rockhard skid plate purchase. Now that it is installed, I suppose it will do the job.

1" of shims to clear the crossover?? Man that's a lot. The back of skid must be hanging down quite a bit. If you had to add that much, somethings not right. I'd contact Rockhard about it.
I only had to shim mine down about 1/8".
Did you look at your exhaust hangers? Maybe something's allowing the crossover to hang down too far. Can you post pics?

Rock Hard Addresses 2010 Fix Issues
I just installed the Oil Pan, Trans, Cat Convert and T-Case skids on my 2010 4Dr Rubicon. I followed the instructions to a tee and suprise, suprise, it rattled at low engine rpm and on bumpy roads.
This being said. I recived an extra piece not listed in the `parts list`, a 3 1/2" x 20" - 1/4" thick plate with 4 holes in it. It was obvious it was a shim for the Trans Cross Member however, I did not initally use it (not in the instrucitons) to attempt to maintain max ground clearance.
After the realization that I needed to go back and add the 1/4" shim plate, all was well.
Very happy and looking forward to climbing some larger rocks with less concern about voiding my warranty for trail abuse.
Very tough stuff!
For what ět`s worth, I installed it under the stock ride height and 32`tires without jacking it up. I rolled under with a creepy crawler for everywhere but the 2 front brackets. I recommend using a jack to put the Oil Pan, Trans skid in place if your doing it by yourself.
I hope that helps prospective 2010 owners with there decisions. If you didn`t receive one, give a call and get hooked up.

Really glad I found this thread...I have a 2010 and installed the RH skid and evap relocation kit this past weekend...I've been hearing vibration noises from what seems like directly below my seat, as well as odd rattling noises from what sounds like the back of the Jeep....I to didn't install the extra 'spacer' becuase the instructions didn't mention it.....after reading this and hearing the vibration, I'm hoping that once i put it in my problems go away......no I'm not sure if that will fix what I'm hearing coming from the back...has anyone heard noises coming from the back?...sounds like i've got a bag of bolts in the trunk (though I don't)......

had this on my 2DR 2011 and it worked very well but did touch the exhaust pipe so I had to put more spacers in.. no big deal...
I sold my 2011 and bought a 2013 4DR and holes didn't line up, the hole for the oil drain is way off... I modified it to at least protect the pan and transmission and the two transmission lines.... but as for the oil pan lining up... its like 3 inch off...
it'll work for now.. oil changes will required me to partially drop the skid...
short term it's going to do what I need it to do, but long term I'll probably end up with a different skid...
