Northridge Grade 8 Hardware Kit for 2015 JK

I plan on having a AEV 2.5" dualsport lift and Teraflex front adjustable trackbar installed on my JKU soon. While they are at it I am planning to have them replace the factory bolts with these Grade 8 bolts from Northridge. However, I'm a little confused with this section of the .pdf from Northridge:

"In 2011 Jeep made a running change to the diameter of both the Front and Rear Track Bar Bolt hole diameter. The 9/16” Bolts are too wide for Jeeps produced after the change requiring the use of the 14mm bolts in stock applications."

What bolts are used in the 2015 JK (probably same as the 2014)? Was this change for 2011 only or every year since then? So, did Jeep fix the problem after 2011? It sounds like they are recommending to use 14mm bolts which is what comes from the factory. BUT, that is for "stock applications". Will the Tereflex trackbar accept the 9/16th bolts? Or, are the post 2011 bracket holes too small for 9/16" bolts?

The problem isn't that the bolts are way to small it's the low grade of bolt they use, when wheeling they like to loosen and then get hammered out, the replacement bolts will be a grade 8 shouldered 14mm bolt. I also check the torque on my bolts periodically

I changed the bolts in my 13 JKU and all of them took the 9/16 bolts including track bars

That part of the PDF is only referring to the trac bar frame side bolts, all the others will fit the 9/16" bolts.
That said don't just throw the 14mm bolts in those holes, test fit the 9/16 first.
I found I had to use the 14mm in the front but the 9/16 fit perfectly in the rear on my 2014

I have a warranty question about the bolts. I am planning on buying a 7/100 or 8/120 maxcare soon but this puts me in a bit of a dilemma. If I change out the bolts and then get the death wobble Chrysler will likely say it is not covered. If I don't change the bolts and get it then it is covered. Anyone has direct experience with this topic that they can share?

What? You are not going to be denied coverage because you replaced a few bolts. Besides, just don't tell them. It's highly unlikely they will even notice. If they do notice, play dumb. It'll be OK, really.
