Created by renowned shaft designer Kim Braly and forged from Tour player feedback, the KBS Tour Series features the most advanced steel shaft technology in the industry. Since its inception in 2008, KBS has set a new standard in steel shafts with its unprecedented growth and acclaim. KBS shafts are utilized in leading club manufacturer’s irons, accepted in every manufacturer’s custom department and adopted by over 150 professionals.

At KBS, we’re focused on maximizing the performance of your irons by providing the most technologically advanced steel golf shafts. Learn why we are the fastest growing steel shaft brand in the industry.


Wanting to pioneer a fresh vision of golf shaft performance and design, FST America Corporation sought the most experienced golf shaft design minds in the golf equipment industry that could integrate innovative designs with our state-of the-art manufacturing facility. Our objective was to produce premium high-performance golf shafts a cut above the rest.

FST introduced Kim Braly Signature (KBS) shafts in early 2008. That first year, several players quickly converted to KBS Tour shafts and multiple wins were recorded that same year. Citing this early success on the PGA Tour and other professional tours worldwide, a clear path was opened for FST’s fresh KBS products to get out to custom fitters and club builders. The number of tour players playing KBS grew since that first year and so did the number of wins on Tour, including several majors. KBS rapidly became the fastest growing steel shaft brand in the industry and has earned a significant share of the market.

Golf Shaft expert Kim Braly joined our team 10 years ago to lead our Research and Development Team on Tour. Throughout his career, Kim has made significant contributions to the golf industry and continues to do so as Head of Director of Research and Development and Tour Operations at KBS. Kim’s lifelong passion for golf and personal involvement with all professional golf tours have resulted in numerous accomplishments that are well documented. For decades, Kim has used the best golfers in the world to validate his designs and assist in the development of new products. During his career, Kim Braly designed innovative golf shafts still being used by club builders and touring professionals throughout the world.

Combining FST’s state-of-the-art manufacturing with Kim’s design expertise, the current KBS Line of golf shafts offers a range of new performance options for junior golfers to the touring professional. Proven on all worldwide tours including the PGA Tour, and most importantly, by our passionate KBS Golf Shaft users worldwide. Player Driven. Tour Proven.
