10 Best Graphite Shafts For Irons 2025 in the United States

The AeroTech SteelFiber fc90 graphite iron shafts come as a set of seven, covering irons 4 through PW, which is ideal for golfers looking to upgrade or replace several shafts at once. These shafts use a .355 taper tip, making them compatible with many standard iron heads. One of the key features is the option to choose your preferred flex, with this particular listing highlighting a Regular (F3) flex, which generally suits mid to moderate swing speeds, offering a good balance of control and distance.

The shafts are designed with a raw length range from 39.5 inches (for the 4-iron) down to 36.5 inches (for the pitching wedge), fitting typical iron length expectations. The SteelFiber line combines graphite's lighter weight with a steel-like feel, helping golfers generate more clubhead speed without sacrificing stability. The kick point tends to be mid to low, optimizing launch angles for better carry and distance, which is especially useful for players seeking more height on their iron shots.

These AeroTech SteelFiber fc90 shafts are a solid choice for intermediate players wanting graphite shafts that blend lightweight benefits with good control, particularly if you fit within the regular flex range. However, fast swingers or those who prefer stiffer flexes might find the Regular F3 option less suitable.

The Mitsubishi MMT 80 Iron Golf Shafts are designed for players looking for a quality graphite option for their irons, especially from 3-iron to pitching wedge. These shafts come in a set of 8 with a standard .370" parallel tip size, making them compatible with many iron head designs. Weighing around 84-86 grams, these shafts fall into a medium weight category that balances control and feel without being too heavy or too light. The stiff flex option helps players with faster swing speeds maintain stability and accuracy.

The raw length of 42" allows for custom fitting to your preferred iron lengths. Customer feedback is very positive, praising performance and consistency. These shafts represent a reliable, medium-weight graphite option with stiff flex, offering better control and feel for iron play.

The Fujikura New PRO Series 115i Graphite Iron Shafts are designed with serious golfers in mind, especially those looking for a premium feel and performance. One of the strongest points of these shafts is their Tour Spec Stiff flex, which caters to players who generate higher swing speeds and seek more control over their shots. The low to mid launch is particularly beneficial for those wanting to achieve a penetrating ball flight. With a set of 8 shafts ranging from 3-PW, it provides a complete upgrade for your iron set.

In terms of construction, these shafts are made of a blend of alloy steel and graphite, offering a balance of durability and lightweight performance, which is crucial for reducing fatigue during a long round. The length of 40.5 inches is standard for many iron sets, making it compatible with a wide range of players.

There are a few considerations. Firstly, the choice of flex is limited to Tour Spec Stiff, which may not suit every player's needs, especially those with slower swing speeds or those who prefer a more flexible shaft for added distance and comfort. Additionally, while the brand Fujikura is reputable, the product's best sellers rank indicates it is not one of the most purchased options in the category, which might suggest limited market penetration or visibility.

The Fujikura New PRO Series 115i shafts are an excellent option for advanced golfers seeking performance and control. Less experienced players or those with different flex preferences may want to explore other options to find a better fit for their game.
