In the new drivers, PING’s engineering team developed several new technologies common to all three models while applying specific advancements to each individual head, producing measurable ball-speed gains while improving sound throughout the series. The added ball speed is attributed to a shallower and thinner VFT forged face design engineered with Spinsistency, a variable roll radius technology proven on the G425 fairway woods and hybrids. The improved and pleasing sound is the result of fine-tuning the frequencies of the head through a new internal rib structure.
