What will a heavier iron shaft do?

Published Jan 22, 2026
A key factor in maximizing swing speed is maximizing muscle activation, which is why certain golfers can swing heavier shafts faster than lighter shafts. Slightly heavier shafts can activate additional muscle groups, effectively “turning on” more speed in a golfer's swing.
What happens if your iron shafts are too heavy?
Nippon suggested that a player should be able to tell largely by feel. A shaft that's too heavy will cause a “labored golf swing.” A shaft that's too light will hurt your ability to make solid contact. When you find the right shaft weight, you'll experience a “high energy swing” with uniform contact.
Is a heavier iron shaft better?
Weight in the shaft is linked to your preference for feel and swing speed. Fast swing speed will benefit from a heavier shaft to provide more control without losing distance. Slow swing speed and tempo will benefit most from a lightweight shaft.
What effect does a heavier shaft have?
The heavier a shaft is, the more likely it is that your golf ball will fly low and with less spin. If it's lighter, the ball will tend to fly higher and spin more. As Briand explains, the weight of a shaft has less impact on swing speed than golfers think, but that lighter shafts could increase the rate of closure.
What are the benefits of a heavier golf shaft?
Heavier shafts also have less torque, which is the resistance to twisting on impact, so a heavier shaft helps prevent slices or hooks and keeps your ball flying straight.
41 related questions foundHow heavy should my iron shafts be?
In general, golfers with slower swing speed and tempo can and should play a lighter shaft. Golfers with very fast speeds and tempo should play heavier shafts. Driver shafts typically weigh 55-60 grams for men and 45-50 grams for ladies. Iron shafts can be as light as 55 grams in graphite, and 130 grams in steel.
How do I know if I need a heavier golf shaft?
If you are struggling to swing through the ball, and are pushing your shots, it is likely the driver shaft is too heavy for your swing. A heavy driver shaft will further reduce your clubhead speed, which will limit your ability to generate sufficient ball speed.
What weight shaft does Bryson Dechambeau use?
According to Schomin, along with the 190-gram head, Bryson is using a 48-inch version of the LA Golf Axis Blue 60 X shaft he plays on the PGA TOUR.
Do I need heavier iron shafts?
Using a shaft that is optimized will lead to a consistently good ball and clubhead contact. That will result in improved accuracy and longer distance. The use of heavier iron shafts is said to contribute to greater accuracy, while lighter shafts are known to increase total distance.
What happens if golf shaft is too light?
Worse, a clubhead that's too light often results in poor swing mechanics like deceleration in the downswing, sequencing issues and a swing path that hits the ball with a glancing blow. “Efficient golfers hit with their body and get their body weight into it,” Mucklow says.
Is a 70 gram driver shaft too heavy?
A 70-gram driver shaft is considered to be pretty heavy but not the heaviest. It falls into the middle but is still on the heavier side when you consider you could go with 50 or 60 grams instead.
Are heavier shafts stiffer?
A stiff shaft is firmer and harder to bend than a regular shaft, and so more often than not, they're also heavier in weight. As a rough rule of thumb, the more speed you generate, the stiffer your shafts should be.
Does heavier shaft increase swing weight?
Golfers can adjust the swingweight of their golf club by changing the weight of the shaft in their club. Assuming the shaft is not increased or decreased in length, an increase of 9 grams in shaft weight will increase swingweight by approximately one swingweight point (increase from D3 to D4, for example).
What happens if your iron shafts are too soft?
It also will be hard to square the clubhead at impact, meaning you will have a tendency to hit your shots to the right. "Play the most flexible shaft you can control," said Scott Hennessey, president of True Temper shafts. "If it's too soft, you'll spray the ball all over the place."
Do heavier golf clubs hit further?
It's the practice of moving weight to positions in the clubhead where it can best improve performance: distance, accuracy, or even feel. We know that, in general, the heavier a club head is the more energy it can transfer to a golf ball if the clubhead speed remains the same or very close to the same.
Does 10 grams make a difference in golf shaft?
While most focus more on shaft flex, shaft weight is equally important. 10 grams may not sound like a big deal, but during the golf swing, it can make a big difference. This weight can make a big difference to feel, clubhead speed and dispersion (the accuracy of your drives).
Will a heavier shaft reduce spin?
Shafts that are heavier tend to do the opposite, lowering ball flight and spin rates. When considering the length of the club, improper length can, many times, lead to shots that are not struck in the center of the clubface.
What shaft does Dustin Johnson use?
TaylorMade P730 DJ Proto
The rest of his irons, from 3-iron to pitching wedge, are P730 DJ Proto irons. These are fitted with True Temper X100 shafts - a shaft he has used in his irons ever since his junior days.
What shafts does Tiger Woods use?

What driver shaft does Rory McIlroy use?
Rory's driver is a 9º head, with the hosel adaptor set a notch lower so the loft plays more like 8.5º. The sliding sole weight is in a pretty neutral position, and the shaft is a Fujikura Ventus Black 6X tipped one inch (to make it play stiffer).
Are lighter iron shafts better?
To optimize the swing speed, golfers with slower swing speeds and slow tempo should use lighter golf shafts. The contrary is correct for heavier shafts, which are better for faster swing speeds. Utilizing heavier shafts may improve accuracy, whilst lighter shafts can enhance total distance.
How do you know if your irons are too heavy?
Common problems which are found by golfers however when golf clubs are too heavy for them include:
- Reduction of club head speed and distance as a result.
- Lower ball flight.
- Poor timing.
- A laboured swing which results in the pressure to feel you need your best swing every time to get decent results.
How can you tell if an iron is too light?
A shaft that is too light will make you feel like the club is going too fast for your swing. It will feel like you have less control over the club throughout the swing and it will make you feel a little uneasy until you slow everything down, this can be dangerous.
What happens if your swing weight is too heavy?
Since swing weight is how heavy or light a club feels to a golfer, it can significantly impact the game. For golfers that are playing with a club that feels too heavy they may start rushing their golf swing and trying to attack the ball in order to get the club to perform.
What does shaft weight do to swing weight?
So the nine-gram rule of thumb for shafts assumes the weight is distributed the same throughout both shafts. A change in the length of the club plays a role in swingweight. Adding or subtracting a half-inch (1.3 cm) to a club's length changes the swingweight by three points (shorter = lower swingweight).
