This Supertech titanium retainer matches springs with a 6.6mm stem and a 7-degree seating angle, providing the correct retention interface for that stem dimension. It is intended for installations that specify a 6.6mm stem retainer at a 7-degree seat, restoring proper spring clamping and compatibility during valvetrain service or rebuild where those stem and angle dimensions are required.
