MOI to the MAX
In the G425 driver series, the primary model is named Max as it elevates the moment of inertia (MOI) to PING’s highest level in history and provide golfers the most forgiving driver in golf. Joining the G425 Max are the LST (Low Spin Technology) and SFT (Straight Flight Technology) to best match a golfer’s swing and launch conditions.
To achieve the new performance levels in the G425 Max (9º, 10.5º, 12º lofts), PING engineers combined key technologies from the G400 Max and G410 Plus. The resulting increase in MOI in the 460cc head comes mainly from a 26-gram tungsten movable weight, which is made possible by weight savings attributed to advancements in the driver’s dragonfly crown technology. The weight can be positioned at distinctive settings over a smaller area than G410 Plus/LST to help shift the center of gravity lower and farther back without sacrificing performance elsewhere in the design. The CG-shifting weight can be secured in one of three settings -- neutral, draw or fade -- to influence forgiveness and shot shape for maximum performance. The average MOI increase is 14% across the three weight positions compared to the G410 Plus, with three combinations of weight position and loft exceeding a combined MOI of 10,000 (gm-cm²).
The LST model (9º, 10.5º lofts) is designed with a pear-shaped head and measures 445cc to deliver spin reductions of approximately 200 rpm compared to the G410 LST and 500-700 rpm versus the G425 Max. The smaller head size of the LST employs a 17-gram CG shifter with three settings (Draw, Neutral, Fade) to fit the launch conditions best suited to the golfer’s swing and desired ball flight.
For golfers who commonly miss their tee shots to the right, the 460cc SFT version (10.5º loft) is engineered with draw bias to help bring shots back on-line and into the fairway. It features a fixed 23-gram tungsten back weight that shifts the CG closer to the heel to promote a right-to-left shot bend of approximately 25 yards compared to the G425 Max model. A lighter swingweight (D1) also helps influence the ball flight correction.
To help contribute to increases in swing speed and ball speed, all three models share proven PING driver innovations, including turbulators for reduced aerodynamic drag and the proprietary T9S+ forged face to accelerate face flexing for more distance. An internal rib structure in the Ti-8-1-1 body improves acoustics for a solid and pleasing sound. Each model also features the lightweight, 8-position hosel for loft (+-1.5º) and lie (up to 3º flatter) adjustments to further dial in ball flight.
