The COMP Cams spring seat is a valve-spring lower seat sized .100 × .770 × 1.3 inches, intended to locate and support a valve spring on the guide. It provides a consistent seating surface for retainers and springs during assembly or repair, helping preserve alignment and stable spring positioning in rebuilt or upgraded cylinder heads and valvetrain assemblies.
