Actually it does fit your late model 5.3. Your vehicle uses 22mx1.5 thread size and has the same location for the o ring. This issue is complicated. The 10575 fits many Ford and FCA vehicles that have much lower bypass, that is why we cannot just change the valve in the 10575. The PH12060 was released with the 22 psi bypass for GM 4 cylinders and then GM changed requirements for V8's as well.
Good to know.
I'm using a Wix on my Chevy due to the 22 psi bypass spec.
