GEN 2 Gorilla glass windshield

[Johnfaeglasgow]

Are you two crash test dummies??

Lol! I didn’t understand your response at first until I read what I wrote...
Nah, just out here in the sticks there’s a dirt road every two miles and traffic are constantly dragging rocks into the highway. It’s infuriating

How is this helpful? According to this article in PowerNation it still gets rock chips that can be repaired?!?!? Stupid if it's true,
since it kind of defeats the purpose....

"HGP specializes in glass encapsulation for various applications for both solar and automotive platforms. The windshield consists of three-layers with conventional soda-lime glass on the outside, Corning Gorilla Glass on the inside and a sound and energy-absorbing layer of polyvinyl butyral (PVB) in between.

The windshield starts at $899 before installation. However, the design allows minor chips to be repaired like any other window and it comes with a two-year replacement warranty for normal damage."

They do sell a windshield that will fit gen2 raptors, however your collision avoidance/autobraking, auto-wipers and auto-highbeams will not work with it, as gorilla glass has very different optical qualities when compared to tempered glass ( which all of the cameras and sensors are calibrated to use).

I get why the auto-wipers are effected, but didn't realize that the auto-high beams use a sensor inside the vehicle. Surprised that auto braking is also using sensors behind the windshield? I thought those used the sensors mounted on the bumpers?

What sort of calibration is required for the cameras related to the glass? All 4 cameras are located outside of the vehicle.

It's the forward facing camera in the windshield that needs to be calibrated, which incidentally needs to be calibrated after an alignment (guess how many shops are actually doing that). Aftermarket glass and calibrating this camera from my experience can be hit or miss. So, I'd personally be skeptical that it is going to work. The other concern I'd bring up is vehicles are now designed to crash with the factory engineered components. While on the surface it would appear stronger is better, that may not be the reality as forces from an impact may traverse differently through the vehicle potentially causing greater damage and/or more harm. The 4 cameras you are referring to are part of the around view monitoring system, which can also require calibration.

Maybe this will help explain the differences?

Thanks Krudenite, that makes more sense.......the purpose isn't to eliminate rock chips, it's more for safety reasons and weight savings.
I know know how important that interior impact resistance can be......I had a pretty tricked out Rubicon with armor everywhere(except the windshield)
and one day while I was doing 75 down the highway a Caddy in front of me ran over a half of an engine pulley lying in the road. Needless to say, the
Jeep doesn't deflect items off the windshield very well, so the pulley came straight for my face, and about 50% of it pierced the windshield and luckily got
stuck there. Glass came in everywhere and luckily I was wearing Oakleys, which kept the glass out of my eyes......not a good day!

This is standard practice with all cars with forward collision warning system. It’s usually a dealer job. I’ve had the windshield on my Mercedes replaced twice, and each time the insurance co. also paid for the calibration at the dealer after the glass co. is done.

In my opinion, it’s more of a CYA for the glass co. The calibration wasn’t even disturbed during the glass replacement.
