The Granatelli billet valley pan cover for LS Gen IV engines includes an O-ring set plus the 595001 adapter and fits LS2/LS3/LS7 applications. This machined valley cover provides a direct replacement for factory parts while supplying the adapter needed for certain sender or breather fittings. Note that the cover does not provide D.O.D. provision, so it’s intended for engines where D.O.D. is not required.
