The Edelbrock two-piece aluminum timing cover for GM Gen III/IV LS series (LS2 and later trucks) with a front-mounted cam sensor hole lets technicians remove or install the camshaft without dropping the damper or steering components. The removable access plate seals with an O-ring for leak prevention. This design simplifies cam service on supported LS2 and later-model applications; not for use with double-roller timing chains.
