FST Corp. Launches KBS TOUR V-X Steel Iron Shaft Family, Engineered for Best-in-Category Stability and Dispersion

FST's CEO expects the shafts, alongside the 2026 graphite lineup, to make "significant contributions" to second-half 2026 revenue.

Rhea-AI Summary

FST (KBSX) launched its KBS TOUR V-X steel iron shaft family, comprising TOUR V-X and TOUR V-X Lite, on September 24, 2026.

Both shafts are available now. TOUR V-X is offered in weights from 105 to 130 grams for players seeking a firmer steel feel. V-X Lite has listed weights of 90, 95, 99, 100 and 102 grams for golfers seeking a lighter shaft. In company testing, the family achieved a strength-to-weight ratio up to approximately 20% higher than many of FST's existing steel iron shafts. The two models share a design intended to reduce shaft bending during the swing.

4 terms

strength-to-weight ratio technical

"achieved a strength-to-weight ratio up to approximately 20% higher"

Strength-to-weight ratio is a measure of how much load or force a material or component can withstand compared with its mass, expressed as strength (like tensile or yield strength) divided by weight or density. It matters to investors because a higher ratio means products or structures can be lighter without sacrificing durability, which can reduce materials and operating costs and improve performance—like a lighter, stronger bike frame that speeds up a ride.

shaft deflection technical

"providing more precise control of shaft deflection through impact"

Shaft deflection is the bending or sideways displacement of a rotating shaft under load, caused by forces like weight, imbalance, pressure, or thermal expansion. For investors, it matters because excessive deflection can reduce efficiency, cause vibration, increase wear, trigger shutdowns, or require costly repairs or redesigns — similar to a tree branch sagging under weight, which signals structural stress that can lead to failure if unaddressed.

clubhead speed technical

"golfers generating higher clubhead speed who want a lighter platform"

Clubhead speed is the speed of a golf club’s head at the instant it strikes the ball, usually measured in miles or kilometers per hour. It determines how much kinetic energy is transferred to the ball and therefore influences how far and fast the ball travels—think of it like the speed of a bat swing in baseball. For investors, clubhead speed matters when assessing golf equipment performance claims, sports-technology products, athlete endorsements, or market demand tied to playing performance.

oem technical

"our fitting network and our OEM partners"

OEM stands for Original Equipment Manufacturer, which is a company that produces parts or components used in the final products made by other companies. For investors, understanding OEMs is important because their performance can impact the supply chain and overall success of major industries, especially those relying on specialized parts. Think of OEMs as the suppliers that provide the building blocks for larger products, like the engine parts for a car.

Boulder, Colorado--(Newsfile Corp. - September 24, 2026) - FST Corp. (NASDAQ: KBSX) ("FST" or the "Company"), a leading manufacturer and marketer of steel and graphite golf shafts and a provider of other golf-related services, today announced the launch of the KBS TOUR V-X family of steel iron shafts, comprising the KBS TOUR V-X and KBS TOUR V-X Lite.

The V-X family represents the Company's newest steel iron shaft platform, engineered to maximize the strength-to-weight ratio while maintaining the signature KBS feel. Its proprietary flex profile and geometric design allow KBS to deliver greater stiffness and stability at a given shaft weight, providing more precise control of shaft deflection through impact. In Company testing, the family achieved a strength-to-weight ratio up to approximately 20% higher than many of the Company's existing steel iron shafts.

Both shafts share a common architecture: a firm butt section, a responsive midsection, and a stable tip profile designed to reduce bending amplitude across the swing. By reducing movement at impact, the Company believes the platform delivers truer flight, tighter dispersion, and improved distance control for players with faster swing speeds, without sacrificing the workability competitive golfers require.

The family's two weight platforms allow fitters to match a player's preferred feel and swing profile:

KBS TOUR V-X

The heavier platform in the family, designed for advanced and elite players seeking maximum stability and a traditional, firmer steel feel. The TOUR V-X offers low-launch, low-spin characteristics and is intended for players who have tested the V-X Lite and want more mass.

• Weights: 105, 110, 115, 120, 125, and 130 grams
• Flexes: R, R+, S, S+, X, and Tour Spec X (TX)
• Tip options: .355″ taper tip and .370″ parallel tip
• Clubs: 3-iron through 9-iron, pitching wedge, and sand wedge

KBS TOUR V-X Lite

A players' model shaft engineered to bring V-X stability to the lightweight steel category, which has historically required players to trade control for weight savings. The V-X Lite targets what the Company calls the "next generation" player: golfers generating higher clubhead speed who want a lighter platform without sacrificing the piercing flight and tight dispersion associated with heavier steel.

• Weights: 90 grams (Regular), 95 grams (Stiff), 99 grams (R/S, parallel tip), 100 grams (X-Stiff, taper tip), and 102 grams (X-Stiff, parallel tip)
• Flexes: Regular, R/S, Stiff, and X-Stiff
• Finish: Chrome

"The V-X family is a generational step for our steel business," said FST Chief Executive Officer David Chuang. "For years, players who wanted a lighter iron shaft had to accept a loss of stability to get there. Now we offer a platform that is stronger for its weight than any steel iron shaft we have previously built, in both a traditional weight range and a lightweight profile."

"Steel remains the foundation of the KBS brand and the largest contributor to our revenue," Mr. Chuang continued. "Launching the V-X and V-X Lite together allows our fitting network and our OEM partners to serve the full spectrum of competitive players from a single platform, and strengthens our position in the lightweight steel category, where we see meaningful room to grow."

Mr. Chuang added that he expects the V-X family, alongside the Company's 2026 graphite lineup, to make "significant contributions" to FST revenue in the second half of 2026.

Both the KBS TOUR V-X and KBS TOUR V-X Lite are now available and can be ordered through KBSGolfShafts.com, authorized KBS fitting partners and distributors, and the Company's KBS Golf Experience retail locations.
