Im going with the 4" TB/AT4 BDS 1805 lift kit and Im trying to decide between a Fox 2.0 and Eibach Pro 2.0. Also just saw the Halo/Elka's that look nice. For some reason the Trail Boss/AT4 1805 kit is only listed with the Fox 2.5 coilovers but the standard trim 6" BDS 1801(FSR) offers the Fox 2.0 snap ring coilover. Anyone know why the TB/AT4 doesnt offer the 2.0's? Should be almost identical lift. I think the Fox coils on the 1801 kit dont require a spacer and the Eibach would? Would that factor into the decision? Thanks

I saw that high clearance bumper. Looks promising. Hopefully it gets added for 2023. Think Super Cruise is too much to hope for? I know it's an off-road truck but realistically you know they see more freeway than dirt.

Ive got a 2019 AT4 but thinking of upgrading in the next year or so. I would really like Super Cruise but I also need the extra couple inches of ground clearance. Id prefer the AT4 or AT4X but not sure that it will offer super cruise in the near future. Has anyone on here lifted a Super Cruise vehicle yet? I imagine it would wreak havoc on the calibration. I've read issues with the older ACC vehicles and lifts. Probably too early to know that but thought Id ask... Thanks

I use the GM order guide quite a bit to see the differences between models and trims. Wanted to see if there were any plans to add Super Cruise to the Sierra AT4 for 2023 and noticed that the AT4X (4SG) is not listed like it is for 2022. ZR2 Silverado is shown for both years. Any thoughts on why this is? I have found the guide to very accurate and up to date on what is and will be available. 2022 - https://www.gmfleetorderguide.com/N...vehicleID=22364&section=oi_def&page=6&butID=3 2023 - https://www.gmfleetorderguide.com/N...vehicleID=22449&section=oi_def&page=1&butID=3

Been a while since I've updated this:

Well... This window didn't even last through the frigid cold California winter this time. Window number 3 Already leaking in this last rain storm!

Here are my numbers on the window. Also, the frame measured about .160" from the glass to the plastic frame.

Just looked over my paperwork from the window installed last week. It is the new part number 84944319. The frame might be a bit thicker but without measuring the old one with a caliper I can't be sure. If anyone measures theirs I can measure mine too ?

Out of curiosity I charted the number of pages of posts by month to see if a trend is forming. My leaks were all after washing, not rain because I'm in California. But still not exactly scientific because obviously leaks are gonna be noticed more in the wet months so impossible to say it's temperature related... Still interesting. We'll see if there is another massive spike in Jan/Feb.

My second window failed after exactly one year, to the day. I noticed after washing it both times. This time was shortly after our first frost. Thermal cycling maybe? Took about 9 days to replace with another new window. I took it to a different dealer this time. They did a much better job but unfortunately the damage had already been done by the first dealer. However, as soon as I opened the door I immediately heard the sound of the pressure equalization flapper valve between the cap and bed. Took a peak in there and guess what! It was dislodged again lying between the bed and cab just like last time. Took them over a month to get the part last time and a week to install it. This time they ordered the part in about a week and we'll see how long the install takes. They have to remove the bed to get to it apparently. I've got a case open with GM waiting to see if theyll do a buy back. I had the caulk job done, and now two windows so that should count as 3 repairs for the same issue. If they don't do something to satisfy me I'll investigate the lemon law route because I have zero faith that this new window wont be leaking come next November.

My second window is leaking again. Same time of year that it happened last year. I'm thinking a thermal expansion issue. We were over 100 two weeks ago and low 30's over night last week. Got a little rain and sure enough, it's dripping again with visible cracks in the frame.

Got mine tonight. Here’s what it says it includes:

Did yours pop out completely like mine did? (Video here: ) How long did you have to wait for yours to come in? While my glass came in remarkably quick, I am still waiting for the vents to come in!

My FUYAO replacement which does not leak (yet) says 43R-000072

My replacement is a fuyao. Still not sure how I got it so fast compared to some on here. Maybe someone else was waiting for one and they mixed us up? I wouldn’t put anything past them. No leaks yet but I’m thinking I might need to take out the truck and flex it a little. To test the theory I can leak test before and after. It is an at4 after all...
