More than three years have passed since PING unveiled its S56 iron at the 2010 U.S. Open -- a blade model that's amassed more than 30 worldwide wins during its life cycle.
Hunter Mahan, Billy Horschel, Harris English, Louis Oosthuizen, Angel Cabrera and Derek Ernst are just a few of the high-profile names currently using the tour-style blade.
Starting Monday morning at Liberty National Golf Course, site of FedExCup Playoffs opener at The Barclays, all of the players in the field using S56 will have the opportunity to test out PING's new S55 iron for the first time.
Available at retail stores starting Nov. 1, S55 features a number similar traits to the S56, including a 17-4 stainless steel body and a tungsten toe weight that provides a higher moment of inertia (MOI) for greater forgiveness and an improved CG.
Other additions to S55 include a larger Custom Tuning Port (CTP) -- the CTP helped distribute weight to the perimeter of the club for improved forgiveness and feel -- thinner face and stronger lofts throughout the set.
Each iron also includes a stabilizing bar in the cavity that helps with improved feel at impact, and distance control in the longer and shorter irons.
According to PING Tour rep Matt Rollins, 10 sets of S55 irons were shipped to the tournament.
One player who's already expected to put the new iron in play is Hunter Mahan. The five-time PGA TOUR winner received his set last week at his Dallas home and was reportedly hitting them higher and longer than his S56 irons during testing.
PING's S55 will be available Nov. 1 in 3-PW.
