Callaway has paid special attention to some of the design aspects on the original Steelhead Iron, including a slightly longer blade length, a slightly more rounded toe and the signature hosel-to-face transition – which will help any player looking to improve their game.

The speed and distance of Steelhead XR Irons is based on Callaway’s next-generation 360 Face Cup technology, which allows the edges of the ultra-thin face to freely flex and release at impact with greater efficiency, adding ball speed that promotes more distance, especially on off-centre hits. The boost in face-speed is so significant that it’s hiked the COR up to almost .830, which is the USGA conforming limit.

More speed and distance on mis-hits is made possible by the modern ‘Hollow Bore-Thru’ hosel design, which allowed Callaway engineers to remove weight from the hosel and reposition it in strategic areas within the head to increase moment of inertia (MOI) for more forgiveness on mis-hits and precisely position the centre of gravity (CG) strategically in the long, middle and short irons.

Great feel and sound come from the new steel-infused polyurethane layer positioned low in the head, behind the lower portion of the face. In addition to absorbing unwanted impact vibration to promote a remarkably satisfying sound and feel at impact, it also helps lower the CG to promote faster ball speed and higher launch characteristics for more distance.

Put it all together and you have an iron that delivers the finest combination of speed, forgiveness, distance and control to ever emerge from the Callaway research and development department.

The new Steelhead XR irons come standard with True Temper XP 95 Stepless steel shafts, or Matrix F15 graphite shafts. There is a wide array of premium aftermarket steel and graphite shafts and aftermarket grips also available.
