The classic compact head of the S55 delivers a TOUR look and feel with all the technology needed to improve your game. With the multi-metal combination of 17-4 stainless steel, tungsten, and a custom tuning port (CTP) the lofts are strengthened but still have a high launch with increased control and distance. A tungsten toe weight adds forgiveness to improve accuracy, and a stabilizing bar offers distance control. The custom tuning port is made from a thermoplastic elastomer for a soft feel and sound at impact. The long irons have a CG that is lower and farther back to launch the ball higher with greater ball speed for added distance. In the short irons, the CG is more forward to flight the ball lower with optimal spin.
- The expanded custom tuning port sits lower in the back cavity to promote higher launch, and is made from a thermoplastic elastomer to soften the sound and feel at impact.
- The stabilizing bar is narrower in the long irons to launch the ball higher with greater ball speed. The bar is wider in the shorter irons for a lower ball flight with optimal spin.
- A high-density tungsten toe weight stabilizes the face to increase forgiveness for improved accuracy.
