Titleist 915D4 Driver

Utilizing Active Recoil Channel™ and Radial Speed Face technology, the 450cc Titleist 915D4 features a forward SureFit weight directly behind the channel for lower spin than 915D2 and 915D3.
Strategic internal weight distribution produces a higher moment of inertia than competitive low spin drivers.
The wide sole channel delivers more distance by actively flexing at impact to launch the ball off the face with higher speed and lower spin.
The high speed face insert with a thick center and radially thin perimeter in the heel and toe, delivers more distance on off-center hits.
