RETURN COSTS & RESTOCKING FEE (ASSEMBLED ITEMS)


🚫 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.

WHAT YOU NEED TO KNOW

The Aerotech SteelFiber fc90 Iron Shaft Bundle Set (0.370") is a set of eight graphite composite iron shafts with a 0.370" parallel tip, enough for 3-iron through PW. Choose Regular (F3) or Stiff (F4) at 90 g. The progressive tip adds height in the mid and long irons.

Before you order: these are parallel-tip shafts for irons with a 0.370" hosel. Every shaft comes at the same 42" raw length. Only need one or two clubs? Buy the fc90 parallel single shaft.


What's in the Set

Set What you get Available in
#3-PW 8 shafts: 3, 4, 5, 6, 7, 8, 9-iron and PW Regular (F3), Stiff (F4)

Shafts only; club heads and grips are not included. Every shaft in a set is the same model and flex. Parallel-tip shafts come at one raw length, so your club builder trims the tip and then the butt of each shaft to fit each iron. Want us to install them? See our Retrofit Service.


Who It's For

Good fit if you...

  • Are reshafting 3-iron through PW with 0.370" parallel hosels
  • Want a higher flight in the mid and long irons and the usual SteelFiber flight in the scoring clubs
  • Want a 90 g graphite composite iron shaft
  • Play at a moderate tempo (True Temper's rating for SteelFiber FC)

Not the right fit if you...


How It Plays

Flight Control tip. SteelFiber FC ("Flight Control") uses the same composite build as other SteelFiber shafts with a softer, progressive tip. True Temper says it gives a higher ball flight in the mid and long irons while keeping the usual SteelFiber feel in the scoring clubs.

Trimmed to fit. True Temper makes the parallel FC in 70g, 80g and 90g, and says it is tip and butt trimmed into 0.370" iron heads. It rates the shaft for a moderate tempo and gives no spin or launch rating.

Which SteelFiber FC Should I Choose?

True Temper publishes no swing speed chart for Steelfiber FC. It sells the shaft by weight and flex, so choose the weight first and then your flex. Here is how the Steelfiber FC options line up on True Temper's figures.

True Temper model Weight (g) Flexes Torque (°)
FC 70 parallel (0.370") 75 Amateur, Regular, Stiff 3.5–3.2
FC 80 parallel (0.370") 85 Regular, Stiff 3.0–2.9
FC 90 parallel (0.370") (this page) 90 Regular, Stiff 2.6–2.4
FC CW 90 taper (0.355") 90 Regular, Stiff 2.6–2.4
FC CW 115 taper (0.355") 115 Stiff 2.9

True Temper labels the parallel weights 70g, 80g and 90g; its spec tables list 75 g, 85 g and 90 g, as shown. Every FC shaft is rated for a moderate tempo. Not sure? Take the Iron Shaft Finder Quiz.

Frequently Asked Questions

How many shafts are in the fc90 parallel bundle set?

Eight, enough for 3-iron through pitching wedge. All eight come at the same 42" length and the same flex.

Should I choose Regular or Stiff?

True Temper publishes no swing speed chart for SteelFiber FC. Both flexes weigh 90 g; Regular has 2.6° of torque and Stiff 2.4°. Most golfers stay with the flex they play now. Not sure? Take the Iron Shaft Finder Quiz.

What launch does the fc90 have?

True Temper says the softer, progressive tip gives a higher ball flight in the mid and long irons. It rates the shaft for a moderate tempo and gives no spin or launch rating.

Do the shafts need to be trimmed?

Yes. Every shaft comes at 42" with a 0.370" parallel tip, so your club builder trims the tip for each iron and then cuts the butt to final length. Tip trimming changes how the shaft plays, so follow your builder's trim chart.

What's the difference between the fc90 parallel and taper sets?

The tip. The parallel set fits 0.370" hosels and every shaft comes at 42". The taper set fits 0.355" hosels with one raw length per club. True Temper lists the same 90 g and torque for both.
