I did some searching last night, I found two old threads about XV products behaving badly, in one there was well documented shoddy build quality, and there was one UCA that failed in use, and was replaced with an upgraded part. This was years ago, pre XV Engineering. No sign of "k" member failures- they aren't K shaped so it's really a subframe. I like the A-body option they are showing as in development. It's been a year and a half, but still there isn't anything like it for old A-body Mopars.
