i dont doubt you, but i have used them in many gm and ford sas scenarios and jeep "upgrades".
when drilling out and single bolting they get fawked up in shithole detroit in short order on year round daily drivers. if you clean and seal em constantly with dry lube/sealer you can go a good ways. but its the drilled out cast on the knuckle that gets wallered out that is the main issue...not super sloppy socket on the heim..
not for me. i have several off road shops with in 1-2 hrs, and nobody stocks shit on the shelf in this world these days.
but, like i mentioned if your using the tapered mount studs, you get much better service over through drilling and straight bolting to the knuckles.
