Project X shafts are always pushing the needle of shaft design and technology to help better players maximize performance and lower scores.

Stepless Design Technology

Stepless Design Technology

Project X shafts incorporate Stepless Design Technology (SDT) where each individual shaft throughout the set is comprised of a specific taper length. This unique design feature optimizes the flex distribution and energy transfer of the shaft without sacrificing control. SDT provides tip stiffness for stronger players, producing greater accuracy, a smooth yet solid feel on impact and optimal trajectory and spin control.

Frequency Matching Technology

Frequency Matching Technology

Frequency Matching is a highly technical method of precisely measuring and defining the flex of the golf shaft through electronic calibration. We believe in Frequency Matching because flex is not only important, it is personal. Measuring every shaft’s oscillation pattern on a digital readout, Frequency Matched shafts are ensured to flex identically throughout the set. Once properly fitted, all your clubs will flex the same and therefore feel the same, helping develop a consistent and dependable golf swing.

Loading Zone Technology

Loading Zone Technology

Project X’s unique Loading Zone Technology is specifically positioned to maximize shaft load for greater energy transfer and increased ball speeds. Loading Zone Technology is created by thinning out the walls of the mid-section of the shaft, causing it to be more flexible, while reinforcing the butt and tip sections of the shaft to maintain stability and control. This provides a very unique design, profile and feel when compared to other shafts.

ISO-6 Technology

ISO-6 Technology

ISO-6 is a revolutionary technology that bridges the gap between what a steel shaft is and what a graphite shaft can be. Traditional graphite laminates are only 35% as symmetrical as steel. Through advanced material modeling and analysis, Project X engineers constructed a new laminate design to eliminate weak spots found in graphite iron shafts due to the lack of symmetry. With ISO-6 being 75% as symmetrical as steel (over 100% better than traditional graphite laminates), graphite iron shafts made with ISO-6 provide superior accuracy in comparison to the competitors’ shafts.
