New and uncut True Temper Tour Issue AMT S400 7 Piece Iron shaft set. The shafts range from 39.5" to 37" in length. True Temper’s Dynamic Gold AMT (Ascending Mass Technology) shafts are designed to get progressively heavier as golfers move from their long irons to their wedges. As a result, long irons launch higher with more spin due to the lighter weight, while the scoring clubs maintain the familiar flight characteristics of Dynamic Gold Tour Issue shafts. The tips are .355 taper.
