🚫 No Returns or Refunds on Assembled Shafts
Please note that all assembled shaft orders are final. Due to the custom nature of this process, we do not accept returns or offer refunds on any assembled shafts. Each order is built to your specifications, and once assembly begins, we are unable to restock or resell the components.
We encourage you to double-check all specs (flex, length, grip, adapter, etc.) before placing your order. If you need help confirming details, our team is happy to assist before you check out.
Returns can be made on non-personalized items and non-assembled items within the US, 60 days after you've received the original order. Items are only accepted on unopened and unused products. Items must be returned in the original packaging.

FST Iron Shaft (0.370" Parallel Tip)
WHAT YOU NEED TO KNOW
The FST steel iron shaft is a step-pattern shaft sold in combination flexes, so one raw shaft can be trimmed to play as either of two flexes. It runs from the light FST 90 (100 g raw, A/R) through the FST 115 (A/R or S/X) to the conventional-weight FST 125 (S/X), all with a 0.370" parallel tip.
Before you order: each shaft is one combo-flex length (41" for the FST 90, 43" for the 115 and 125). How much you trim from the tip sets the flex and fits it to the iron, then you butt-trim to playing length. Order one per club, or let our Retrofit Service cut and install them.
Who It's For
Good fit if you...
- Want a steel shaft you can trim to the flex you need
- Want a lighter steel option: the FST 90 is 100 g raw
- Prefer a conventional stepped steel look
- Have irons with a 0.370" parallel-tip hosel
Not the right fit if you...
- Want a stepless shaft with a stiff tip and a lower flight: see the FST Pro Stepless
- Have irons with a 0.355" taper tip: this shaft is 0.370" only
- Want a shaft already made for each iron, with no trimming to work out
- Are not sure which tip your irons take: take the Iron Shaft Finder Quiz first
How It Plays
Step pattern. The standard FST is a stepped steel shaft, with visible steps along its length.
Combination flex. Every FST build covers two flexes, A/R or S/X. The tip trim decides which one it plays as, so one shaft model can be built for a range of players.
Light to standard weights. The FST 90 is the light option at 100 g raw and 41" long; the FST 115 and FST 125 are 43" shafts at 115 g and 125 g. The A/R FST 115 has a 13" parallel tip section, the S/X builds 11" and the FST 90 10".

Will It Fit Your Irons?
This shaft is for irons with a 0.370" parallel-tip hosel. Each shaft is one combo-flex length: the amount you tip-trim decides whether it plays as the softer or firmer flex and fits it to each iron, then you butt-trim to playing length, so order one shaft per club.
Not sure which tip your irons take, or how much to trim? Take the Iron Shaft Finder Quiz, contact us, or let us cut and install them with our Retrofit Service.
