Project X Catalyst Black Shaft ... Featuring the proprietary Project X Iso-6 material technology, Catalyst is engineered to replicate steel alloy properties over 100% better than traditional graphite laminates. This allows for an extremely stable shaft that maximizes constancy and distance control while providing the benefits of a graphite body design. Catalyst also features a reinforced tip section which, unlike traditional graphite, delivers torsional resistance comparable to that of steel—improving stability during turf interaction for better impact on less than perfect shots!

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.

PLEASE NOTE:  Be sure that the irons you are looking to shaft accept a 0.370 PARALLEL TIP shaft PRIOR to purchase.  If unsure, please check with the club manufacturer.  Parallel shaft trim protocols call for these to be trimmed from the tip based on the iron to be installed. See chart below for Manufacturer recommendations.  After installation, butt trim to finished playing length.
