Qi4D drivers utilize refined shaping, multimaterial construction, a faster face with a new and improved roll radius, and four moveable Trajectory Adjustment System (TAS) weights to provide you with the perfect blend of speed and forgiveness off the tee.

Features:

• <p>The re-engineered head profile increases ball speed thanks to improved aerodynamics developed through advanced simulations</p>
• <p>New modern address shape provides the perfect balance of inertia and speed to help golfers achieve more speed and distance</p>
• <p>Qi4D drivers feature a new and improved roll radius, yielding more consistent spin across vertical impact locations</p>
• <p>Utilizing four Trajectory Adjustment System weights (9gx2 / 4gx2) provides the golfer our most mass efficient way to adjust flight and spin. • 4° loft sleeve can be used to adjust loft, lie and face angle for optimized flight</p>
• <p>Reax Shafts™: A revolution in shaft fitting, based on 11 million shots captured over 20+ years, allows golfers to quickly identify their rotation rate and play a shaft that matches their unique swing profile. More precise shaft fitting helps golfers achieve more centered contact, increased speed, distance, and accuracy</p>
• <p>New and improved cut-through Speed Pocket™ protects ball speed and reduces spin on low-face strikes</p>
