S400 Aluminum 4.21" Weld on flange.
This flange is a flat faced flange 3" Inside diameter. In most cases, used to weld onto a "Race Cover" to make it a V band outlet like a normal Borg Warner .63 A/R Cover.
Pair this flange with our compressor outlet flange and clamp combo to convert your race cover hose outlet into a V band setup.
