Taper-Tip vs Parallel-Tip Golf Shaft Replacement
Taper and parallel describe a component interface. A replacement order still needs the exact head, shaft and build specification before a professional confirms fitment.

Document the shaft, then confirm the whole order
Two real shaft variants; head fitment is still unconfirmed
| Field | KBS TOUR Stiff · taper | KBS TOUR Stiff · parallel |
|---|---|---|
| Tip diameter | .355 inch | .370 inch |
| Listed weight | 120 g | 130 g |
| Raw length | 37.5–41 inches across listed club positions | 43.5 inches before model-specific preparation |

Fictional order A: head documented for .355 taper
Manufacturer table lists the taper family and club-specific lengths.
Still required before a shop confirms the order: Exact iron position and discrete part; head generation and documented interface; clubmaker measurements.
Fictional order B: head documented for .370 parallel
Manufacturer table lists the parallel blank; its note requires tip and butt trimming to build length.
Still required before a shop confirms the order: Exact head interface and existing alterations; correct manufacturer build schedule; professional finished specification.
The heads are hypothetical and have no real manufacturer pairing here. A matching tip number alone cannot complete either order. The clubmaker must verify the whole assembly; this worksheet gives no trimming amounts, hosel modification instructions or buying recommendation.
The short version
- Confirm the exact component documentation.
- Do not treat tip diameter as a performance ranking.
- Trimming and fitment belong to the model-specific professional build.
Use the dimension for the task it answers
KBS explains the common.355 taper and.370 parallel tip interfaces. That distinction helps match components; it is not evidence that one diameter inherently hits farther or suits every stronger player. Exact products can have their own construction and preparation requirements.
The two orders above use fictional heads. They demonstrate the fields a real shop must complete from current model documentation, not an interchangeable-parts list for all irons.
Identify the whole replacement
Write the head’s generation and handedness, iron number, existing shaft, tip specification and intended finished build. A shaft pulled from another club may have been trimmed or altered. A matching label does not prove it will reproduce the original set’s length or progression.
Ask the clubmaker which part number and preparation method the manufacturer specifies. Do not convert a general explanation into a DIY tipping or hosel-modification procedure.
Separate replacement from refitting
Replacing a broken shaft to match a set is a different goal from testing a different weight or profile. If the goal changes, revisit the fit rather than quietly choosing a convenient component.
Bring the evidence to the fitting session. For ordinary equipment care, use the material-and-finish checklist.
