PAC Racing valve spring seats and cups are a great way to prevent dancing springs, which would tear up your aluminum heads. High performance racing engines place extreme pressure on the springs. These retainers are essential for use on aluminum heads. They fit the inside or outside diameter of the springs, preventing spring seat movement.
