FST 90 Steel Iron Shafts

  • Available in A/R combination flex only

Trimming Instructions

FST 90 Steel Iron Shafts is rated 4.8 out of 5 by 4.
Rated 5 out of 5 by from Expectations Met I was looking for the higher ball flight with the soft feel of the Maltby Heads as well as distance with the regular flex. As these are not my primary set, I also wanted to stay within a fixed budget. All of those have been met..The ball flight is a little lower then my other irons (Shafts- XP105 S300 @ 24.99 ea.). I have built clubs(Stiff and Regular) for friends before and they really like those shafts. A great shaft....

Rated 5 out of 5 by from FST90 Steel Shaft I replaced the shafts in my wife's irons which were too heavy and wrong flex. She now hits the ball higher and straighter with less effort. The FST 90 was a better choice than any of the graphite options for irons. I soft stepped the A/R to make them closer to L Flex.

Rated 5 out of 5 by from Great Product I got this shaft because my 7 iron shaft snapped. I was impressed with the performance of the shaft. I thought that the ball flight was nicer and the club performed better than before. I felt like the ball flight was better.

Hi. My name is elie Do you ship to spain? I have a set of G20 irons and they are sinor flex. I did a fiiting with ping and now i need regular and 90 grams or grafite 70 grams. What can you recomend that will not mlbe do expensive to change my shafts.

Asked by: elie
The Ping G20 irons use a .355" taper tip shaft. We do not have any steel shafts in the 90 gram weight range in a Senior flex with a .355" taper tip. In a 75 gram weight graphite shaft we also do not have a Senior Flex in a .355" taper tip.

My son broke the shaft of his Adams A12 OS 7 iron. Adams used an 85 gram shaft made for them by True Temper. Would this be a good replacement or do you have a better suggestion?

Asked by: WBgolf
That shaft would be ok if you need an A or R flex. The closest replacement is code# TT0066 True temper GS 85. We keep some of them on hand, but if you need one we don't currently have on hand, we can special order it from True Temper and have it to you within 1-2 weeks.

I'm replacing a broken shaft in a rocketblade 7 iron with a rocket fuel 85 shaft. Is the FST 90 the best option or do you have another recommendation?

Asked by: Bailey
The FST 90 is a fair replacement option. You could also look at True Temper XP95 (TT0113)

I'm looking to pull the uniflex shafts from my Callaway X20s, do you recommend these if I cut them as a regular flex ..I feel uniflex is too wippy at the 3 & 4 ...and of course the heads are heavy

Asked by: golfer101
Generally a Uniflex is meant to be between an R and S flex so cutting to an R flex would be more flexible then the Uniflex. The FST 90 as well as the other FST shafts we stock test and play more flexible then their listed flex. So I do not feel that the FST 90 will accomplish what you are trying to do here. With an FST shaft you might want an S flex to get to the feel you are looking for.

Is this the shaft thats in taylormade speedblade 85.  I need a stiff flex. Is this shaft available? 

Asked by: Jeremy67
The Speedblade 85 in the Taylor Made irons is made exclusively for Taylor Made by FST and there currently is no aftermarket version of this shaft available. The FST 90 (FS0011) shaft is only manufactured in the A/R combination flex and would likely be the closest replacement. My next choice would be the FST 115 (FS0012) in the S/X flex. Once cut for installation it would end up being in the mid 90 gram weight range and the playing characteristics would match pretty close.

Does Tip & Butt Trimming mean you'll cut the shaft to a specific iron length? I want to buy this shaft for a TaylorMade Burner 2.0 7-iron, but my goal is to get it as close to the spec length of 37". Or in this case what length shaft do I need? Gracias!

Asked by: JDR2682
The FS0011 is a combo flex iron. You can achieve the flex of either A or R depending on the amount you trim from the shaft tip. You will follow the recommend amount of tip trimming per our trim code to create your flex, then the remaining amount of trimming will come off the shaft butt to create your desired finished playing length. Feel free to contact our customer service dept. if you need further information.
