Project X LZ steel features proprietary Loading Zone Technology for improved energy transfer and a smooth feel. The reinforced tip and butt sections act to maintain the tour proven stability you expect from Project X with a mid-trajectory launch profile. LZ technology is achieved by using variable wall technology in both butt and tip sections and a reduced stiffness midsection. Golfers can not only feel Loading Zone technology, but see it as well in the rapid, tapered steps out of the grip through the mid-section of the shaft.
