Where are you seeing this? I looked at 2022 limited configurations for both Custom and LT Trail Boss and don't see anything like what you are describing.
Under the “Exterior” in Build and Price. Maybe just a Canadian option? Just trying to determine what it is exactly that makes it $2300. No parts depts or dealers seem to be able to give me a straight answer. I’ve seen Truck Hardware makes a caliber guard for the 2014-2018 1500s and it’s $120 so wondering why Chevy is out to lunch.
Yeah, that doesn't show on the US configuration page. There was someone on the GM Trucks forum that showed a shield for the brake lines on the rear axle that I don't believe I have on my truck. I just saw it this past weekend and forgot to look while I was out in the barn a while ago.
