How To Extend Golf Clubs: Step-by-Step DIY Guide + Costs

Struggling with inconsistent shots, a nagging slice, or back pain after a round of golf? These common frustrations often point to a single, overlooked culprit: your golf clubs are too short for your body and swing. Learning how to extend golf clubs isn’t just for exceptionally tall players; it’s a precise modification that can unlock a more comfortable stance, a smoother swing path, and ultimately, a better score.

Extending golf clubs is a DIY-friendly process that involves adding a shaft extension plug to the butt end of the shaft using high-quality two-part epoxy. The key steps are accurate measurement to determine the needed length, proper preparation of the shaft, and allowing the epoxy to fully cure before installing a new grip.

Leveraging extensive analysis of established club-fitting principles, this guide unpacks the entire process of how to extend golf clubs. We’ll walk you through determining if this modification is right for you, gathering the correct tools, following the step-by-step installation process with a focus on safety, and implementing a long-term maintenance plan. This is the complete blueprint for achieving a custom fit at home.

Key Facts

Maximum Extension Limit: To maintain shaft integrity and safety, you should never extend a steel golf club shaft more than 2 inches.

Precision is Paramount: Even a minor adjustment of just 1/4 inch in club length can significantly alter ball flight and shot accuracy.

Long-Term Performance: For golfers with modified clubs, professional fittings are recommended every 12-18 months to ensure the setup continues to match any changes in physical condition or playing style.

Swing Flaw Correction: Properly extending a golf club can help correct a slice by encouraging a more natural, inside-out swing path.

Bonding is Critical: A secure and durable modification relies on using a high-quality, two-part epoxy specifically designed for golf clubs, which requires a curing time of approximately 24 hours.

Is Extending Your Golf Clubs the Right Move for Your Game?

Extending golf clubs is beneficial for taller players needing better posture, golfers with physical limitations seeking less strain, and those looking to improve distance or correct swing flaws like a slice. Before you begin the process of learning how to extend golf clubs, it’s crucial to diagnose if this is the right solution for your specific issues on the course. Do you find yourself hunching over the ball or suffering from back strain after a round? Your club length might be the culprit.

This modification is more than just adding length; it’s about customizing your equipment to match your body’s unique biomechanics. Proper club length is the foundation of a good setup, influencing everything from your posture and stance to the club’s path through the hitting zone. When your clubs are fitted correctly, the game becomes easier and more comfortable.

Here are the primary reasons why extending your golf clubs can be a game-changer:

For Taller Players: Golfers who are significantly taller than average often struggle with standard-length clubs. This forces them into an uncomfortable, hunched-over posture, which restricts their swing and leads to inconsistency. Extending the clubs allows for a more athletic and natural stance, promoting better balance and a more repeatable swing.
To Alleviate Physical Strain: If you suffer from back problems or have limited flexibility, clubs that are too short can exacerbate the issue. A longer club allows for a more upright posture, reducing the strain on your lower back and spine during the repetitive motion of the golf swing. This can lead to more comfortable rounds and less post-game soreness.
To Correct Swing Flaws: Your equipment can either help or hinder your swing mechanics. For players who consistently slice the ball (a shot that curves hard to the right for a right-handed golfer), a club that is too short can contribute to an “over-the-top” or outside-in swing path. Extending the shaft can help promote a more desirable inside-out swing path, making it easier to square the clubface at impact and hit straighter shots.
To Increase Distance and Consistency: A longer club shaft creates a wider swing arc, which can translate to higher clubhead speed and, consequently, more distance. More importantly, when a club fits your body, your alignment and posture improve, leading to more centered strikes on the clubface. This improved contact is the key to both consistent distance and better accuracy.

Step 1: Accurately Determine Your Ideal Extension Length

This step’s outcome is a precise measurement for your extension. You will have either a DIY-derived length based on personal and standard club measurements or a highly accurate recommendation from a professional fitting. This is the most critical phase of learning how to extend golf clubs. An incorrect measurement can negatively affect your game, so precision is essential. While a professional fitting is the gold standard, you can get a very reliable estimate at home.

Pro Tip: Before making any permanent changes, remember that even a small 1/4 inch adjustment can make a big difference. Measure twice, cut once!

Here is how to determine the correct length for your extension:

Measure Your Current Club: Place your club in a normal address position on the floor. Use a measuring tape to measure from the ground, up the back of the shaft, to the very top edge of the grip cap. Note this measurement.
Take Your Wrist-to-Floor Measurement: Stand on a flat surface in your regular shoes with your arms hanging relaxed at your sides. Have someone else measure the distance from the crease of your wrist to the floor. This measurement is a key indicator club fitters use to determine ideal club length.
Compare to Standard Charts: Use your wrist-to-floor measurement and your height to consult standard golf club fitting charts available online. These charts provide a baseline for how much longer or shorter than standard your clubs should be. For example, a common rule of thumb suggests that golfers taller than 6 feet may need clubs that are 0.5 to 1 inch longer than standard.

While these DIY methods are effective, they don’t account for other critical variables in your swing. A professional fitting uses advanced tools to provide the most accurate recommendation.

A general rule of thumb for drivers is to add 1 inch of length for every 6 inches of height over 5’6″, starting with a base of 43 inches for a 5’6″ golfer.

To help you decide which path is best, here is a comparison of the two primary methods for determining your ideal club length:

Method	Pros	Cons
DIY Measurement	Cost-effective, can be done at home, provides a solid baseline.	Doesn’t account for swing speed, impact position, or dynamic lie angle. Less precise.
Professional Fitting	Highly accurate, uses launch monitors and swing analysis, considers all personal swing dynamics.	Involves a cost for the session, requires finding a qualified fitter.

For the most accurate results that factor in your unique swing DNA—including your swing speed, address position, and ball flight patterns—a professional fitting is the undeniable best choice.

Step 2: Gather the Essential Tools and Materials

This step’s outcome is a complete and organized set of all required tools and materials. You will have everything on hand to perform the extension safely and effectively, including the correct type of shaft extension and epoxy. Before you can begin the hands-on work of how to extend golf clubs, you need to assemble your workshop. Having the right equipment ensures a smooth, safe, and professional-quality job.

Quick Fact: Choosing the right extension is crucial. Always match the extension material (steel or graphite) to your existing shaft to maintain proper feel and flex!

Here is a comprehensive list of everything you’ll need, its purpose, and key considerations:

Item	Purpose	Key Consideration
Shaft Extensions	The core component used to add length to the shaft.	Must match your shaft material (steel or graphite) and inner diameter.
Vise with Rubber Jaws	To hold the club securely without scratching or damaging the shaft.	Rubber padding is essential to protect the shaft’s finish and integrity.
Heat Gun	To soften the old epoxy holding the grip and clubhead (if disassembling).	Use even heat and keep the gun moving to avoid overheating and damaging the shaft.
Shaft Saw or Tube Cutter	To make a clean, straight cut on the extension to achieve the desired length.	A fine-toothed blade prevents fraying, especially on graphite shafts.
High-Quality Two-Part Epoxy	A strong adhesive used to create a permanent bond between the shaft and the extension.	Use a golf-specific epoxy that is designed to withstand the high torque of a golf swing.
Sandpaper (Various Grits)	To roughen the inside of the shaft and the outside of the extension for a stronger bond.	Start with a coarser grit and finish with a finer one for a clean surface.
Cleaning Solvent	To remove any old epoxy, oils, or debris from the shaft and extension.	Isopropyl alcohol or mineral spirits work well. Ensure the area is well-ventilated.
New Grips	You will need to replace the old grip after extending the club.	This is a great opportunity to install a grip that fits your hand size.
Grip Tape & Solvent	Used to install the new grip onto the extended shaft.	Double-sided grip tape and a grip-specific solvent are required.
Ferrules (Optional)	A small plastic piece that provides a clean transition between the shaft and hosel.	Mostly cosmetic, but gives the club a professional, finished look.

Step 3: Follow the DIY Club Extension Process

This step’s outcome is a securely extended golf club. You will have successfully prepared the shaft, bonded the extension, and finished the club with a new grip, ready for the course after a full curing period. This is where your preparation pays off. Follow these instructions meticulously to ensure a safe and durable result. The process can be broken down into three main phases: preparation, attachment, and finishing.

Never extend a steel shaft more than 2″. Exceeding this limit can compromise the structural integrity of the shaft, creating a safety hazard and negatively impacting performance.

Preparation

First, you must prepare the club for the new extension. A clean and properly prepped surface is essential for a strong epoxy bond.

Remove the Old Grip: Secure the club in the vise. Use a utility knife with a hook blade to carefully cut the old grip from top to bottom, making sure not to cut into the shaft itself. Peel off the old grip and the grip tape underneath.
Clean the Shaft Butt: Use your cleaning solvent and a rag to remove any remaining tape residue from the top portion of the shaft. The surface should be completely clean and dry.

Attachment & Curing

This is the most critical part of the process where you install the extension plug.

Prepare the Surfaces: Lightly sand the inside of the shaft’s butt end and the outside of the extension plug. This roughs up the surfaces and helps the epoxy create a much stronger mechanical bond. Clean both surfaces with solvent afterward to remove any dust.
Mix and Apply Epoxy: Mix the two-part epoxy according to the manufacturer’s instructions. Apply a liberal amount of epoxy to both surfaces—the inside of the shaft and the outside of the extension plug.
Insert the Extension: Carefully insert the epoxied extension plug into the butt end of the shaft. Push it in fully, giving it a slight twist to ensure the epoxy is evenly distributed.
Clean and Cure: Quickly wipe away any excess epoxy that has squeezed out using a cloth with some solvent. Stand the club upright against a wall and allow it to cure for a full 24 hours. Do not handle or move the club during this time.

Finishing Touches

Once the epoxy has fully hardened, you can complete the assembly.

Add a Security Pin (Recommended for Steel Shafts): For an extra layer of security, it is highly recommended to drill a small hole through the side of the shaft and the extension plug inside. Insert a small steel pin coated in epoxy, then file down any protruding parts so it sits flush with the shaft. This provides a mechanical lock that prevents the extension from ever twisting or coming loose.
Cut to Final Length: If you used a full-length extender, measure your club to its new desired total length and carefully cut the extension to size using your shaft saw.
Install the New Grip: Apply new double-sided grip tape to the end of the shaft. Apply grip solvent to the tape and the inside of the new grip, and quickly slide the grip onto the shaft. Ensure it is properly aligned with the clubface before the solvent evaporates.

Step 4: Manage Aftercare and Ongoing Maintenance

This step’s outcome is a long-term maintenance plan. You will know exactly how to clean, store, and inspect your modified clubs, and when to seek professional reassessment to ensure they always match your game. Your work on how to extend golf clubs doesn’t end after the grip is installed. Proper aftercare and a proactive maintenance schedule will ensure your newly modified clubs perform reliably for years to come.

Pro Tip: Set a calendar reminder at the start of each golf season to inspect your extended clubs’ joints. A quick check can prevent a mid-round failure.

Immediate Aftercare

Final Cure: Allow the new grip to set for at least a few hours before handling it. It’s best to wait a full 24 hours after the initial extension cure before hitting any balls to ensure the entire club assembly is rock solid.
Initial Inspection: Before your first round, give the club a few firm waggles. Listen and feel for any clicking or looseness at the joint, which could indicate a poor epoxy bond.

Long-Term Maintenance

Regular Cleaning: After each round, clean your grips and shafts with mild soap and water. Dry them thoroughly. This prevents the buildup of dirt and oils that can degrade materials over time.
Proper Storage: Store your clubs in a cool, dry place. Avoid leaving them in a hot car trunk for extended periods, as extreme heat can potentially weaken the epoxy bond over time and cause grips to warp.
Joint Inspection: Periodically, and especially at the beginning of each season, inspect the area where the extension was installed. Check for any signs of cracking or separation. If you notice any issues, it’s best to take it to a professional for re-epoxying.
Annual Reassessment: Your body and your swing can change over time. It’s a good practice to reassess your club length annually. If you start noticing consistent mishits or a return of old swing flaws, it might be time for another measurement.
Professional Re-Fitting: To ensure your clubs are always perfectly optimized for your game, consider a professional fitting every 12-18 months. This is especially important if you experience significant changes in your physical condition, such as weight changes or improvements in flexibility.

To ensure you have everything you need for a successful DIY project, investing in a complete golf club extension kit can simplify the process and provide professional-grade materials.

FAQs About Extending Golf Clubs

Can you lengthen any golf clubs?

Yes, you can lengthen virtually any golf club, including drivers, irons, and putters, as long as you use the correct type of extension. Shaft extensions are made for both steel and graphite shafts, and you must match the extension material to your club’s shaft material to maintain its intended flex and feel characteristics.

How tall should you be for extended golf clubs?

There’s no exact height, as arm length (wrist-to-floor measurement) is a more critical factor. However, as a general guideline, golfers taller than 6’1″ often benefit from clubs that are between 0.5 to 1.5 inches longer than standard. The best way to know for sure is to get a professional fitting or take a precise wrist-to-floor measurement.

What happens if your golf clubs are too short?

Playing with golf clubs that are too short forces you to hunch over, leading to poor posture and an overly steep swing plane. This can cause a range of problems, including inconsistent ball striking, loss of power, a tendency to slice the ball, and physical strain, most notably in the lower back.

How much does it cost to get my golf clubs extended?

While prices can vary, the DIY cost primarily includes the shaft extensions, a new set of grips, and materials like epoxy and grip tape. If you opt for a professional service at a golf shop, the cost will include these materials plus a labor fee per club. Doing it yourself is generally more cost-effective if you plan to extend multiple clubs.

What is the maximum you can extend a golf club?

For safety and performance reasons, it is strongly recommended that you never extend a steel shaft more than 2 inches. Extending it beyond this limit can compromise the shaft’s integrity, alter its flex and balance point (swing weight) too drastically, and increase the risk of breakage during a swing.

Final Summary: Key Takeaways for Extending Your Clubs

Successfully learning how to extend golf clubs is an empowering DIY project that can deliver significant improvements in comfort, consistency, and performance on the course. By transforming a standard set of clubs into a custom-fitted tool, you give yourself the best possible chance to play to your full potential. The process is straightforward when approached with precision and patience.

The entire journey, from diagnosis to execution, hinges on a few core principles. Now that you have the complete blueprint, you can confidently decide whether a DIY extension is your next project to improve your game.

Accurate Measurement is Everything: The foundation of a successful extension is an accurate measurement. Whether you use the DIY wrist-to-floor method or invest in a professional fitting, getting the length right is non-negotiable.
Use the Right Materials: Do not compromise on quality. Use a golf-specific, high-strength two-part epoxy and ensure your shaft extensions match the material (steel or graphite) of your existing shafts.
Prioritize Safety and Security: Adhere to the 2-inch maximum extension rule for steel shafts. For the most secure bond, include the step of drilling and pinning the extension, which provides a mechanical lock to supplement the epoxy’s chemical bond.
Long-Term Care Ensures Longevity: Your modified clubs require ongoing attention. Regular inspections of the epoxy joint and periodic reassessments of your club length will ensure they remain a safe and effective part of your game for years to come.
