How to Find the Right Golf Shaft

By Spencer Lanoue
July 24, 2025

Choosing a new golf club is exciting, but all the attention usually goes to the clubhead, while the shaft - the actual engine of the club - is often an afterthought. Finding the right golf shaft can tame a slice, add yards to your drive, and give you the consistent feel you've been missing. This guide will walk you through the essential factors of a golf shaft - flex, weight, kick point, and torque - so you can make an informed decision and find the perfect match for your swing.

Why Your Shaft is the "Engine" of Your Club

Think of your golf club like a high-performance car. The clubhead is the sleek, shiny body - it looks great and has a lot of technology built into it. But the shaft is the engine. It’s what transfers all the energy you generate in your swing to the golf ball. An engine that’s mismatched to the car's frame will be inefficient, unpredictable, and might even break down. The same is true for your golf club.

An incorrect shaft can lead to all sorts of problems:

  • Shots that fly too high and rob you of distance.
  • Shots that fly too low and can't hold the green.
  • A persistent slice or hook that you just can't shake.
  • "Feels dead." An inconsistent feeling at impact that erodes your confidence.

Getting the shaft right means you’re giving yourself the best possible chance to deliver the clubhead to the ball squarely and with maximum speed. Let's break down how to do that.

The Four Pillars of a Golf Shaft: What You Need to Know

When you're looking at shafts, you'll see a lot of specs and jargon. It can be overwhelming, but it really boils down to four main characteristics. Understand these, and you're well on your way to finding your match.

1. Shaft Flex: Finding Your Speed Limit

Shaft flex is the most talked-about A-lister of shaft characteristics. It simply refers to how much a shaft bends during the swing. You need a shaft with the right amount of bend to match the force you create, which is primarily determined by your swing speed.

Choosing the correct flex helps the clubface return to a square position at impact. Think of it like a perfectly timed whip. Too much or too little bend at the wrong time throws the whole sequence off.

Shafts are generally categorized into these five flexes:

  • L (Ladies): For swing speeds typically under 75 mph with a driver.
  • A or M (Senior/Mature): For swing speeds between 75-85 mph.
  • R (Regular): The most common flex, suited for swing speeds between 85-95 mph.
  • S (Stiff): For swing speeds hovering between 95-110 mph.
  • X (Extra Stiff): For powerful swings that are 110 mph and above.

What Happens If Your Flex Is Wrong?

- Shaft is too stiff: If you don't swing fast enough to properly bend a stiff shaft, you'll struggle to square the face at impact. The shaft won't "kick" forward enough, often leaving the face open. The result? Shots that feel harsh, fly lower than they should, and tend to leak out to the right (for a right-handed golfer).

- Shaft is too flexible: If your swing is too fast for a soft shaft, it will bend too much. This can cause the clubhead to lag too far behind your hands and then snap forward too aggressively, often closing the face at impact. The result? Shots that can feel "whippy," fly too high, and curve wildly to the left (a hook for a right-handed golfer).

How Do I Know My Swing Speed?

The best way is to visit a golf shop or practice facility with a launch monitor. In a few swings, you'll have an accurate number. If that's not an option, you can use your typical driver distance as a rough guide:

  • Under 200 yards: Likely Ladies or Senior flex.
  • 200-240 yards: Likely Regular flex territory.
  • 240-275 yards: You're probably in Stiff flex.
  • 275+ yards: You most likely need an Extra Stiff flex.

This is a starting point, not a perfect science. Be honest with your distances! This isn't about ego, it's about hitting better shots.

2. Shaft Weight: The Feel and "Secret" Speed Factor

Shaft weight is a dramatically underrated part of the fitting equation, but it fundamentally impacts your tempo, feel, and control. Shafts can range from around 40 grams (ultralight woods) to over 130 grams (heavy steel irons). While a lighter shaft might sound like a simple recipe for more speed, it’s not always the right choice.

Lighter Shafts (e.g., 50-65g for a driver):

  • Pros: Can help increase clubhead speed because it's easier to accelerate a lighter object. They can also promote a higher launch.
  • Cons: For some players, especially those with a quick or aggressive transition from backswing to downswing, a light shaft can feel unstable and hard to keep track of during the swing. This can lead to less control and inconsistent strikes.

Heavier Shafts (e.g., 70g+ for a driver, 115g+ for irons):

  • Pros: Provide more stability and a better sense of where the clubhead is throughout the swing. This is great for stronger players or those with a fast tempo, as it helps prevent the club from getting out of sync.
  • Cons: A shaft that's too heavy can be hard to swing fast enough, leading to a loss of distance and a feel of having to "work" too hard to hit the ball.

Finding the right weight is about balancing speed with control. If you have a smooth, rhythmic tempo, you can often play well with a range of weights. If you have a quick, powerful swing, you'll probably benefit from a heavier shaft that keeps things stable.

3. Kick Point (or Bend Profile): Launching It Your Way

Kick point describes the area of the shaft that bends the most. This characteristic has a direct influence on the launch angle and spin of your shots. Matching your kick point to your swing delivery helps you optimize your ball flight.

Low Kick Point

A shaft with a low kick point bends closest to the clubhead. This flexion helps "kick" the ball up into the air, creating a higher launch and more spin. This is ideal for:

  • Golfers who struggle to get the ball airborne.
  • Players who have a slower swing speed and need help to maximize carry distance.
  • Anyone who wants to hit higher, softer-landing shots into greens.

High Kick Point

A shaft with a high kick point bends closer to the grip. This produces a more stable tip section, resulting in a lower, more controlled ball flight with less spin. This profile works best for:

  • Golfers who hit the ball too high and are losing distance to "ballooning" shots.
  • Players with very fast swing speeds who need to manage spin andtrajectory for more piercing drives.
  • Playing in windy conditions where a low ball flight is an advantage.

Mid Kick Point

As you’d guess, a mid-kick point shaft bends most in the middle. It’s the "Goldilocks" option, offering a blend of control and launch. It provides a medium launch and medium spin profile that fits a huge number of golfers. If you’re unsure where to start, a mid-kick point shaft is almost always a safe and reliable bet.

4. Torque: The Twist-Resistance Factor

Torque is a measure of the shaft's resistance to twisting during the swing. Measured in degrees, it’s a massive component of how a shaft “feels.” When you swing, your forces cause the shaft to twist slightly. Torque determines how much.

Low Torque (around 2-3.5 degrees): Shafts with low torque twist less. They feel extremely stable and stout, almost 'boardy' to some. These are often preferred by players with fast, aggressive swings because they help keep the clubface from twisting open on the downswing. A low-torque shaft provides more control for powerful players who generate a lot of force.

High Torque (around 4-5.5+ degrees): Shafts with higher torque twist more. This makes them feel smoother and more "active" at impact. A bit more twist can help slower swingers who tend to leave the clubface open, as the shaft's kick can help release and square the clubhead. However, for a fast swinger, a high-torque shaft can feel loose and unpredictable, leading to more hooks.

Most golfers with average swing speeds will fit nicely into a mid-torque shaft (around 3.5-4.5 degrees), as it provides a great blend of feel and stability.

Putting It All Together: The Fitting Process

Knowing this information is powerful, but testing is how you confirm the right fit. It's like buying a suit - you need to know your measurements, but you still have to try it on.

The Gold Standard: A Professional Fitting

Nothing beats getting fit by a qualified professional. They’ll use a launch monitor to get precise data on your swing speed, ball speed, launch angle, and spin rates. You’ll be able to hit multiple head-and-shaft combinations back-to-back and see the data for yourself. More importantly, a good fitter can watch your swing and translate your feel into the right product - something data alone can't always do.

A DIY Approach

If a professional fitting isn’t in the budget right now, you can still test shafts smartly. Head to a golf store or range that has demo clubs and a hitting bay with a simulator.

  1. Establish a Baseline: Start by hitting your current driver or 7-iron. Pay attention to the ball flight, feel, and the data on the monitor. This is your control group.
  2. Test One Variable at a Time: Use your baseline to test theories. If you think your shaft's flex is too weak, try the same clubhead with a stiff shaft. Think the weight is too light? Ask if they have a heavier option. By changing only one thing at a time, you can isolate what's actually making a difference.
  3. Trust Feel and Results: A shot might look great on the monitor, but if it feels terrible, it's probably not the one. Confidence is everything. Look for the shaft that gives you the best combination of tight dispersion (your in-play area), good distance, and a feel that lets you swing freely.

Final Thoughts

Finding the right golf shaft completely changes what’s possible with your golf swing. By moving beyond brand names and focusing on the core characteristics - flex, weight, kick point, and torque - you can filter out the noise and select a piece of equipment that genuinely complements your game rather than fighting against it.
