It just holds a caliper…torques down to spec I don’t see the issue here. Kit seems well made. I have a few friends running a lug nut kit on their SRW’s with no issues.Looks like another flat-bracket "conversion" that stresses the caliper mounting pins. Over a thousand dollars for crappy engineering.
I’m not familiar either at all with newer trucks as I don’t work on them. I posted a few years ago about converting and no one had something to say. I was going to go get a rear end from an HD with calipers. My buddy who helps with crazy projects over the years said he would do it but really wasn’t thrilled one bit. I can see it in his body language.You need an OEM caliper/bracket; probably with the OEM rotor as used on a GMT800 or newer 3500 DRW. You should look at how the calipers are mounted on the newer trucks.
I am not an expert on the newer-style discs except that they don't mount the caliper in a way that stresses the mounting pins. Either the caliper holds the pads, and caliper thrust is taken by an iron protrusion from the mounting system; (NOT a "flat bracket") or there's a separate iron bracket that holds the pads, and the caliper has no thrust. It just clamps the pads--the pad thrust is taken by the iron bracket that holds 'em.
Cheap-junk "conversions" use a flat bracket with no caliper thrust provisions; which means caliper thrust is taken by the mounting pins--a stress they were never intended to handle.
It may not be different. There's heaps of conversion kits that have terrible engineering; most of them make the SAME mistake. It's readily visible in your second photo.People who have SRW using a same but different kit report no issues. Why is this kit any different?

Keep you updated as I drive my truck. Thanks for the concern!Yes, the kit appears to expect the pins to sustain the braking forces.
They should have instead provided abutments for the calipers, like the OEMs did.
That’s why the calipers in the picture have those flat surfaces on either side, to press against the abutments (except the kit didn’t provide for them).
Let the buyer beware.
Here's what OP's aftermarket kit is missing: The caliper abutments aren't provided on the mounting bracket. The OEs include these for good reason (pictured), while many third-party retrofit providers assume they're unnecessary... or at least expect unsuspecting buyers.
