Titleist 915 D2 Driver 10.5 Degree Regular Flex Aldila Shaft Right HandedFive years in development, the Titleist 915 driver features a new technology behind the clubface called the Active Recoil Channel (ARC), which allows the face to flex more evenly at impact, reducing spin and increasing ball speeds across the face. The clubface itself is more forgiving thanks to a new design and material while a lighter, ultra-thin cast crown saves weight, which has been repositioned towards the edges to boost the moment of inertia (MOI). Titleist says internal testing has shown the D2 version is 15 yards longer in total and the D3 is 20 yards longer than their predecessors.
“ARC moves the centre of gravity slightly forwards compared to previous models,” Stephanie Bezilla, Director of Titleist metalwood development, told TG. “But we’ve been able to reallocate mass from the face insert change and internal pocket geometry, allowing us to put ARC in and maintain high overall MOI.”
The 915 retains two head designs – the D2 is 460cc with a full pear profile and more draw bias, while the D3 is the deep-faced, lower spinning 440cc head with less draw bias and a lower trajectory. Both also feature Titleist’s SureFit hosel, which allows for independent loft and lie adjustability. The moment of inertia has been increased over previous models thanks to internal weight pockets on the crown, which allow weight to be moved lower and further back in the head.
