COBRA’s patented PWRSHELL technology continues to offer increased speed and higher launch even on stronger lofted irons. The forged PWRSHELL Face insert in the RADSPEED iron is made of a high-strength 17-4 stainless steel, allowing for a thinner and more flexible face design that increases ball speed on and around the Sweet Spot.

In addition to the above-mentioned technologies, the RADSPEED Variable Length Irons feature progressive head shapes (two-piece metalwood construction on 4-7i and one-piece construction on 8-SW), groove shapes (V groove for reduced spin in the long irons and U groove for added spin in the short irons), and hosel lengths (shorter in the long irons and taller in the wedges) to optimize distance, launch characteristics, and accuracy for each respective iron category – long irons, mid-irons and wedges.
