Shaft Specs

Stock Shaft

Project X LZ Blackout: Project X LZ steel features proprietary Loading Zone Technology which produces maximum shaft load during the downswing for 7% greater energy transfer to the ball at impact for more distance.

Loading Zone Technology is achieved through variable wall technology in the shaft’s butt and tip sections and a reduced stiffness in the midsection. Golfers can not only feel the technology, but see it as well in the rapid, tapered steps out of the grip through the midsection of Project X LZ.
