The Titleist 915D2 is designed for maximum forgiveness and increased distance off the tee. The long, wide, and deep Active Recoil Channel runs from the heel to the toe of the club and allows the face to flex at impact. This flexion boosts ball speeds and reduces spin, a combination that results in longer drives. The addition of the channel moved the center of gravity (CG) forward, so Titleist used 8-1-1 titanium to make the crown thinner, and removed material from lower stress areas in the clubhead to keep the CG low and deep for maximum forgiveness. Also making the 915 drivers more forgiving is the Radial Speed Face. This forged face insert is thinner around the perimeter, especially near the heel and toe to retain ball speed on mis-hits. The result is a less significant decrease in distance when the ball is struck off-center. The 915D2 is larger at 460cc than its D3 counterpart, with a pear-shaped profile. This allows the 915D2 to be even more forgiving off the tee with a greater moment of inertia (MOI). The 915D2 also promotes slightly higher ball flight than the 915D3, but Titleist makes it easy to dial in the correct specs for your swing with the SureFit Tour hosel. The SureFit system allows loft and lie to be adjusted independently. With 16 unique combinations you, or a Titleist certified 2nd Swing Clubfitter, can find the setting that gives you optimal launch conditions and ball flight.
