Ping drivers are known to promote faster ball speed across the clubface. To that end, the ping K15 driver boasts a large face profile and high moment of inertia (MOI). K15's bread and butter, though, is to help guys rotate the clubface to a more square impact position and, subsequently, hit straighter shots. The head tries to "square up" dynamically (as you swing) due in part to a meaty, heel-side external pad along the sole.
Ping K15 driver "Straight Flight Technology" positions 10 percent of the head's mass toward the heel, promoting more face rotation and a straighter ball flight. The clubface is longer toe to heel than the G15 to increase ball speed (and forgiveness) on off-center hits.
Ultra-thin Crown Technology
Weight saved by thinning the crown was re-distributed to SF Tec's external weight pad to optimize the center of gravity and generate a high Moment of Inertia for added forgiveness.
Straight Flight Technology (SF Tec)
SF Tec provides substantial heel weighting to help square the face for exceptionally straight drives tee shot after tee shot.
Enhanced Face Design
The K15's larger surface area is highly forgiving on off-center hits and generates faster ball speeds for added distance.
