The PING S55 8pc. Iron Set with Steel will help you add distance while still maintaining control and forgiveness. Vertical stabilizing bar provides great distance control and high-density tungsten toe weight stabilizes the face for better forgiveness and accuracy. In the long-irons, CG is lower and farther back in the head for higher launches, faster speeds and greater distance. In the short-irons, CG is more forward for lower ball flights and precise spin. Enhanced Custom Tuning Port (CTP) is made of elastomer for great sound and feel and is placed lower within the back cavity to allow for higher launches.
