TaylorMade R540XD Driver: High, Long, and Forgiving The large 400cc stainless steel head on the R540XD Driver boasts a large sweet spot and massive moment of inertia (MOI) for greater forgiveness on mis-hits. A large, deep hitting area above the center of gravity makes the XD easy to launch. The improved Inverted Cone Technology provides a larger COR Zone that equals higher ball speed and super lightweight graphite shafts are tip-soft and mid-torque to promote a high launch angle and long carry. CAD-optimized center of gravity positioned low and back to promote a high launch angle and reduced spin Crown lines enhance aiming and shot-consistency Inverted Cone precision milled on the inner side of the clubface, engineered to dramatically expand the size of the COR zone Tuned Weight Cartridge inserted into a port in the back of the head, engineered to precisely tune the shaft with the clubhead Club Loft Lie Length Swingweight 8.5 8.50 590 45" D2 9.5 9
