It's called Max 10K because it eclipses the 10,000 g-cm² combined Moi threshold, setting a record and making it our straightest and most forgiving driver ever. A fixed backweight, our largest head profile, and a Carbonfly Wrap crown help G430 Max 10K launch the ball higher with less spin for consistently longer and straighter results. Trajectory Tuning 2.0 utilizes a lightweight, aerodynamic hosel sleeve that provides eight positions to customize your trajectory for maximum distance and accuracy.
