KBS Generation Steel Iron Shaft (.355) & (.370)
KBS Generation Steel Iron Shaft (.355) & (.370)
KBS GENERATION
Steel Iron Shaft
Designed for younger players and lower swing speeds, GENERATION brings high-launch, spin-supporting performance and KBS accuracy to a lightweight steel platform.
Lightweight steel that helps young players launch the ball
GENERATION is based on the E.I. curve of KBS MAX and tuned for the needs of younger golfers. It helps slower developing swings produce higher trajectory, useful spin and accuracy without the burden of traditional adult-weight steel.
Higher Launch
Designed to help young players create a playable iron trajectory and carry the ball more effectively.
Spin Support
Added spin helps keep shots airborne and can improve landing control at lower club speeds.
Manageable Steel Weight
Approximately 80β89g in the discrete taper models, with purpose-built parallel configurations for custom assembly.
Made for developing swingsβnot scaled-down adult builds
Trajectory
High
Helps create a more playable flight at lower speed.
Spin
Added
Supports carry and softer landing iron shots.
Fit Priority
Player Specific
Fit to size, strength, tempo and measured speed.
.355 taper and .370 parallel are not interchangeable builds
Start with the clubheadβs hosel specification. Then choose the matching shaft configuration and follow its correct club-selection or trimming method.
.355 Taper Tip
Discrete, club-specific shafts
- R2: 3iβ9i and PW

Select the matching club shaft
Every taper shaft is chosen for its intended club. One selected variant equals one shaft.
Regular begins at 4i; R2 and Stiff include 3i. Select only combinations shown as available.
Confirm whether the head requires .355 taper or .370 parallel before ordering. For .355, match the discrete shaft to the club and butt trim as required. For .370, tip trim for the intended club first, then butt trim to final playing length. Trimming changes shaft performance.
- Verify hosel diameter with the clubhead manufacturer
- Confirm the playerβs fitted length, grip size and total club weight
- Never apply .370 instructions to a .355 taper shaft
- Professional junior fitting and assembly are strongly recommended
Age is only a starting point
Two golfers of the same age can need very different equipment. The best build accounts for height, wrist-to-floor measurement, hand size, strength, tempo, strike pattern and measured speedβand should be reassessed as the player grows.
Correct Length
A club that fits the player supports posture, center contact and confidence.
Correct Grip Size
Hand size matters for comfort, face control and the ability to hold the club securely.
Correct Total Weight
Shaft, head, grip and finished length must work togetherβnot as isolated specifications.
Before you order
Are the available tips .355 and .370?
Yes. The product uses .355-inch taper and .370-inch parallel options. The β.255β measurement is not an available specification and appears to be a typo.
What is the difference between the two tip options?
The .355 version uses discrete shafts selected for a specific club. The .370 version is a parallel, trim-to-fit shaft that requires tip trimming for the intended club and butt trimming to final length.
Which flexes are available in .355 taper?
Your listing offers R2, Regular and Stiff taper-tip shafts. R2 and Stiff are listed from 3iβPW; Regular is listed from 4iβPW.
Which .370 option is currently available on this listing?
The current Grater Golf variants show one R2 .370 choice. KBS also displays an R/S parallel choice on its manufacturer page, but it is not presently represented in your Shopify variants.
Are these shafts sold individually?
Yes. Order one shaft for each club being assembled. Choose the club-specific variant for .355 builds; for .370 builds, order the required quantity of single-length blanks.
Can the same trimming method be used for both tips?
No. Do not tip trim a discrete .355 taper shaft as though it were a .370 parallel blank. The .370 version requires a model- and club-specific trimming plan.
How should I choose a junior shaft?
Use the golferβs measurements, hand size, strength, tempo and measured speed rather than age alone. A professional fitting is the best way to determine the correct shaft and finished build.
Need help choosing .355 taper or .370 parallel?
Grater Golf can help confirm hosel compatibility, flex, club selection, parallel shaft configuration, quantity, grip size and finished length before you order.
Contact Grater GolfShaft only. Clubhead, grip, ferrule, assembly, trimming and installation are not included unless specifically selected. Product appearance and availability may vary. Verify the exact selected shaft and all build specifications before cutting or installation.
