Hot Launch C523 Irons

Hot Launch C523 irons combine maximum distance and forgiveness in a traditional cavity back design. The C523 Irons are made from extremely soft 431 stainless steel, providing superior feel and performance.

VIBRCOR Technology – C523 irons feature even more VIBRCOR technology! VIBRCOR is a high-grade TPU strategically placed in the deep undercut pocket to create a new speed-inducing and feel-enhancing internal technology. VIBRCOR creates a distinct feel of the clubhead at impact that dampens sound and shock, while also creating perimeter weighting around the entire clubhead for maximum forgiveness and power and ball speed enhancement off the face.
Compact Design with Sharper High Toe – A new shape for the C523 Iron features a more compact design, a thinner topline and a sharper high toe that promotes myriad game-improvement benefits in a classic iron. The more compact design of the C523 Iron has removed weight from the top line to create an ultra-low CG. The ultra-low CG placement promotes a high launch, stability at impact and added forgiveness on off-center hits.
Wide Sole / Deep Undercut Design – The wide sole of the C523 Iron and its deep 360-degree undercut cavity is optimized for playability, turf interaction and ease of launch. The wider sole of the C523 offers superior bounce and increases launch for cleaner, high-flying shots. The wider sole design leads to cleaner turf interaction for more consistent shot making. The 360° undercut cavity creates more face flexing and faster ball speed across the entire face.
Toe Weighted Design – Advanced toe weighting has been strategically increased and made more visible in the new C523 Iron design. This added toe weighting maximizes stability on impact and provides better off-center hit distance from the face of the iron and elongates the sweet spot and creates a pure feel off the face of the irons.
Power Lofted Setup – The lower and deeper CG allowed the C523 irons to be power lofted to create an extreme distance iron. Power lofting in this forgiving iron design promotes both distance & optimized height that achieves maximum distance without sacrificing the peak apex trajectory.

Ultra-Light Premium Shafts – The C523 Iron comes stock with the super-light UST Mamiya HL-SST graphite shaft that range from 55 to 60 grams depending on the flex. It is also available in a True Temper XP-85 steel shaft. The UST Mamiya HL-SST shafts feature Stabilized Shaft Tech, a softer tip and a mid-range flex. Stabilized Shaft Tech is an added cross weave that reduces ovaling for better stability during the loading and unloading of the shaft. The True Temper XP-85 steel shaft is designed to deliver maximum peak trajectory for explosive distance and are an excellent option for players wanting a higher ball flight with a moderate ball spin.
