Anyone trim their pinch seams for 37's?

About to mount some 37's to my 2.5" lift (trimmed fenders). How many of you trimmed your pinch seam to make 37's fit under flex? Is this absolutely necessary?

Trimming is the best option. If you are concerned with moisture protect the edge with a an elastic sealant in addition to paint.

There are a lot of threads discussing this topic.

Yeah, pinch seams need trimmed even for running 35's. Even OEM rock rails could use trimming.

Your 2014 should already bee trimmed from the factory. My '13 was. I believe Jeep started to trim these up mid year '13.

I'll take a picture and show you what I'm working with. You can be the judge. 👍

Looks great! Did you trim the seam? I think you guys are right. My 2014 seems to have much less of a pinch seam than those of other JK's I've looked at on the net prior to any modifications.

Pinch seams are definitely trimmed from the factory. Just cut my rails two inches.

Have the same set up and yes you have to trim.

I not only trimmed I beat the hell out of them to get a smoother edge by curling the seam over a little.

Then tested and at full stuff, I hit the pinch seam, flat fender and bumper at the same time.

Added 1" to the bump stops and they are great now.

On my 2010, trimming, touch-up paint, J-B Weld and then touch-up paint on that was my approach.

Had to trim my rubi-rails, too.

The newer 2dr still need trimming, but 4dr come with already trimmed pinch seams nowadays...

still had to trim my 2014 JKURX rails, though, to fit my 37s.

FYI: the 2 doors are trimmed from the factory also as of mid cycle 2013. It is not just a 4 door thing they did.
