Better than the OEM Hardware
Got tired of broken studs on my manifolds on my Ford 5.4L so bought this kit. They are stainless steel so are of better quality than the OEM ones. Installation is not for noobs. No more leaks from my exhaust manifold gaskets or broken studs. Time will tell if they last. Have driven about 15000 miles with no problems so far.

Key item to exhaust install.
I replaced my exhaust studs on 5.4 F-150 when installing headers. These were easy to use with the socket head end. No complaints and time will tell on longevity. Watch the install on YouTube: Mustangjackson67
