NIPPON N.S.PRO STEEL
NHK Spring Co. LTD.’s automotive value-spring alloy served as the genesis of a revolution in the golf shaft industry. When Nippon Shaft’s N.S. PRO 950GH came to market in 1999, it was the first consistently-made sub-100 gram steel shaft in the world. Light weight steel shafts allow some players to increase their swing speeds and thereby adding distance. All Nippon Shaft products are “constant weighted,” meaning that every iron in a set, from 3-iron to pitching wedge weighs the same. Tour Professionals play constant weight iron shafts almost exclusively. There is no good reason the rest of us should do otherwise.
“Constant weighting is a Nippon Shaft specialty,” says Hiro Fukuda of Nippon Shaft USA. “It doesn’t make sense to have a 3-iron that weighs more than your pitching wedge. The pros want a constant weight throughout their set for consistency.” I could not agree more. As my knowledge of golf shafts evolved, I stopped using parallel blanks and have never gone back to them.
Nippon Shaft developed proprietary golf shaft materials and specialized heat-treatment production processes resulting in high performance golf shafts that have great feel, consistency and performance. These productions lines raised the bar on steel shaft quality and consistency. Shaft to shaft linear consistency in a set is excellent, creating sets of matched bend profiles well beyond what can be achieved by frequency matching parallel blanks. The N.S.Pro family of steel shafts can be installed in any orientation, the redial consistency is excellent
The N.S.Pro Steel shafts are available in 75, 85, 95, 105 and 115 gram models. Like typical graphite driver shaft models they increase in stiffness as they increase in weight. That means the 95 gram S is stiffer than the 85 gram S. Once again, the diatribe we often hear that one manufactures S is not the same as another manufactures S, is shown to be a fundamental lack of understanding of golf shafts. A Nippon Shaft 95S is not the same as an 85S. When looking at golf shafts, the weight and stiffness together must be considered. That is why it is important to see a club fitter that offers a range of weight and stiffness options.

Nippon N.S.Pro 750GH
Ultralight steel is limited by the wall thickness of the butt section of the shaft becoming so thin it is unstable. Nippon addressed the problem in the ultra light Nippon N..SPro 750GH by laminating a four axis carbon fiber wrap to the butt. This is the same material used in many graphite shafts to control torque and ovaling. The shaft launches mid high and follows the stiffness profile pattern of the N.S.Pro family of shafts. Torque ranges from 2.6 in the 78 gram R flex to 2.3 in the 85 gram S flex. This is a unique ultralight weight steel iron shaft design.
Nippon N.S.Pro 850GH
The Nippon N.S.Pro 850 is an exceptional alternative to graphite in the 85 gram shaft weight class. By virtue of being steel, the torque is low compared to carbon fiber products in the same price range. It fits exactly in-between the N.S.Pro 750 and the 950. Like those shafts, the loss of stiffness from point to point is consistent, creating the optimal flow of energy transfer from your hands to the club head. Torque ranges from 2.1 in the 86 gram R flex to 2.0 in the 90 gram S flex. This is a mid high launching super light weight iron shaft design.
Nippon N.S.Pro 950GH
The 95 and 105 differ only in weight. The most popular of the Nippon N.S.Pro models is the 95 gram 950GH. It is offered as an option in many branded clubs. It has a uniform loss of stiffness from butt to 12″ from the tip. There it stiffens slightly for good control of the delivery of the head. Shaft to shaft linear and redial consistency in a set is excellent. Torque ranges from 2.1 in the 93 gram R flex to 1.7 in the 105 gram X flex. This is a mid high launching light weight iron shaft design.
Nippon N.S.Pro 1050GH
The 105 gram Nippon N.S.Pro 1050GH is exactly the same as the 95 gram N.S.Pro 950. It is slightly heavier for the stronger player that prefers extra weight to enhance his feel. Shaft to shaft linear and redial consistency in a set is excellent. Torque ranges from 2.0 in the 94 gram R flex to 1.7 in the 113 gram X flex. This is a mid launching iron shaft design.
Nippon N.S.Pro 999GH
The Nippon N.S.Pro 999GH is an ascending weight steel shaft set. The set uses the 105 gram design in the high lofted clubs and the 95 gram design in the low lofted clubs. The result is a consistent balance in the set and MOI matches with less weight added to the high lofted heads. They are ion plated with a dark nickel finish.
Nippon N.S.Pro 1150GH
The Nippon N.S.Pro 1150 has a different profile from the rest of the Nippon N.S.Pro model line. It is a different shaft, not simply the next weight step up. The butt is stiffer. it is a fitting option for someone with an aggressive transition and will play more like a Dynamic Gold. Torque ranges from 2.0 in the 113 gram R flex to 1.6 in the 127 gram X flex. This is a mid to mid low launching iron shaft design.
