KBS Shafts
Steel shafts are the No. 1 choice for irons on all pro tours. Golf professionals and skilled amateurs alike appreciate consistency and accuracy and, as a result, have long preferred steel shafts in their irons.
Steel provides unmatched stability and a fresh feel for true feedback at impact, and the all-new KBS Steel Shafts use an intelligent design to enhance steel performance even more with Moment of Inertia (MOI) Technology combined with a proportional reduction in mass and radius during the step progression. As a result, premium KBS Steel Shafts are engineered to respond to your hands, especially just prior to impact, and optimize every shot.
KBS Technology
Golfers have been waiting for years to see a tangible difference in steel shaft design, so FST proudly introduces the KBS Series steel shafts — an all-new premium line of steel shafts engineered by industry-acclaimed steel shaft designer Kim Braly and featuring advanced Moment of Inertia technology.
“Shaft performance is critical in placing the clubhead in the correct position at impact, but most steel shafts on the market today fail to reach the level of performance and feel necessary to respond effectively in the players’ hands, especially just prior to impact,” says Braly, whose steel shafts designs are currently being played by many of the Top 10 players in the world. “The KBS steel shafts use an intelligent design to upgrade the performance with MOI technology and a proportional reduction in mass and radius during the step progression.”
The new KBS Series steel shafts are unlike anything on the market today. FST researched a wide variety of tubular structures that endure large stresses or loads and applied a revolutionary new approach with MOI analysis. KBS steel shafts also incorporate FST’s high-quality precision manufacturing processes, such as:
• Exclusive ‘Oil-Quench’ tempering method which produces shafts that are arrow-straight from butt to tip.
• Tapered tip construction to provide a solid metal-to-metal bond in the hosel and tour-proven feel at impact.
• Higher-than-traditional center of gravity construction to allow for more mass in the clubhead.
• Matching shaft weight and frequency to the strictest tolerances to ensure peak playing performance and guaranteed repeatability.
FST remains exclusively dedicated to the design and development of high-quality steel golf shafts, and KBS technology will re-introduce true performance benefits of playing steel to golfers around the world.
Headquartered in Boulder, Colorado, FST is a leading designer, manufacturer and distributor of high-quality steel gol fshafts, supplied to golfers around the world. TaylorMade, Cleveland, and Tommy Amour's use of FST 's premium steel shafts has earned FST a strong reputation within the golf industry.
KBS Wedge
One of the industry’s only steel wedge shaft engineered with ‘moment of inertia analysis,’ the KBS wedge provides increase stability and enhanced feel. Unlike other wedge shafts, the KBS wedge incorporates the unique KBS design that proportionately reduces shaft mass and step radius equally along the shaft’s entire center line which delivers greater performance with every shot. Beautiful black nickel finish also reduces glare, maximizing your focus for critical short game shots.

KBS Hybrid Hybrid clubs are a favorite option for trouble lies and for distances where fairway woods and long irons are problematic, but only the KBS Hybrid shaft gives you high performance in hybrid clubs along with the feel and stability of advanced steel technology. Lighter weight and with more tip action, the new KBS Hybrid steel shaft features a gradual stepless taper starting at the anchor location (between the hands) and continuing to the tip just above the hosel). The wall thickness proportionately increases as the outside diameter decreases, which enhances stability and keeps the hybrid head tracking toward the target.
KBS Tour Series
Designed for better players, the KBS Tour shaft was engineered with ‘moment of inertia analysis’ to increase stability from ‘grip to clubhead’ to enhance the results of well-executed swings. By reducing the mass and radius of each step in equal proportions along the shaft’s center line, the KBS Tour shaft delivers optimum stability resulting in efficient energy transfer from the player’s hands to the clubhead. In addition, the KBS Tour shaft incorporated step-by-step Moment of Inertia analysis to reduce shaft ‘interference’ during a player’s well-executed swing.
