Default Hard top cracks from fasteners

I just noticed that my hard top is cracking where the bolts hold it to the body. Rear bolts on both sides have the same crack. Is anybody else seeing the same? I'm definitely going to come up with a solution for mine. Is anybody else interested in a kit for this?

I'll have to check mine, sounds like it could be a problem. I know there has been a thread about people damaging the front panels from the bolts that go through the sound bar as well. Maybe make this into a poll to. If I have the issue I would be interested in a fix though.

The crack is the same for both rear bolts.

Is there any way to start a pole in edit mode? Or do I have to start a new thread?

Hey Woods, the photos sure look like the fasteners might be cranked down just a bit too tight. Don't take this as a criticism, only as an observation. Those top fasteners should only be snugged down, if you see the top material deflecting then you shouldn't go any farther. the top appears to be made up of SMC (Sheet moulded compound). this is not a true fiberglass type of product and it is not known for it's great flexability. Get large flat ''fender washers'' at
Lowes or Home Depot or any hardware store and place one under each bolt head. This will spread the pressure on the SMC over a much greater area and will also firm up the cracked spots. Putting washers on prior to cracks developing will probably help to prevent them, as long as the bolts aren't cranked down too tight...Remember this just an opinion guys, if you roll it and a washer takes you out it's NOT my fault

Is there a torque spec for these bolts that anyone is aware of?

You bring a great point, in that this is what I'd expect a dealer to say. Not giving you a hard time, you really bring a good point that folks should know about. The fact that this isn't fiberglass is bad news. If it was fiberglass one could chalk this up to gel-coat cracks. But to your point these cracks may actually go through the entire structure.
I only use a screwdriver with a torx bit to tighten these bolts. Not using a ratchet or anything. Here nor there, I think this is another example of how Jeep should have done it. I'm going to make some 10 gauge plates that cover the square area in the picture. I'll attach them with double sided tape and call it the way it should have been made.
