Extensions are a useful component you may want to consider as part of your stabilizer setup. But with so many lengths and materials available, which one is right for you—or do you even need one?

In this article, we’ll cover:

• What stabilizer extensions do
  

• How to choose the right length
  

• Whether to go with aluminum or carbon
  
  

What Extensions Do

Extensions are installed between your riser and your V-Bar mount. As the name suggests, they extend the total length of your stabilizer system.

What does that do?

1. It shifts your center of gravity forward, making the bow more front-heavy.

2.  This forward bias creates a greater tendency for the bow to “spin” downwards toward the ground after the shot—especially useful for archers who like a dynamic follow-through.

Choosing Extension Length

Extension length plays a major role in your bow’s feel and reaction. For full system tuning advice, check out this complete guide on stabilizer length selection.

But here’s how to think about extension length by itself:

 Consider a 2-inch or shorter (or no extension) if:

• You want a slower, smoother reaction with minimal spin
  
  

• You have a methodical shot process with strong emphasis on aiming
  
  

• You plan to use heavy mass weight on your stabilizers
  
  

 Consider a 3-inch or longer extension if:

• You want a faster, livelier shot reaction with more spin
  
  

• You have a rhythmic or dynamic shot process
  
  

• You use lighter stabilizer mass weight
  
  

In short:

Longer = livelier reaction

Shorter = slower, more controlled feel

Extension Material: Aluminum vs Carbon

Most stabilizer extensions come in aluminum or carbon. Here’s a breakdown:

Aluminum Extensions

Machined from a single piece of aluminum with threaded ends.

Pros:

• Extremely durable
  

• Affordable ($25–$50 for a quality model)
  

• Very straight and true
  

• Thinner diameter = better wind efficiency
  
  

Cons:

• Less vibration damping
  

• Lower stiffness (which some archers prefer)
  

• More post-shot resonance
  
  

Best for:

Archers looking for a budget-friendly, no-fuss option that’s built to last. If durability and simplicity are your top priorities, a quality aluminum extension will perform reliably for years.

For an exceptional aluminum extension consider the EDGE Aluminum Extension.

Carbon Extensions

Constructed with bonded aluminum end caps and a carbon center tube.

Pros:

• Stiffer—great for supporting heavy stabilizers
  

• Superior vibration damping
  

• Quieter with less post-shot resonance
  
  

Cons:

• More expensive ($50–$100 for a quality model)
  

• Cheap models may lack straightness or durability
  

• Bulkier = less wind efficient

Best for:

Archers who want the best possible feel and performance from their setup. If you’re willing to invest in premium gear, a carbon extension offers smoother feedback and superior control—one reason many elite-level shooters prefer them.

For a carbon extension that is straight, durable, and includes internal damping consider the EDGE Carbon Extension.

Final Thoughts

Choosing the right stabilizer extension comes down to matching your gear to your goals. Whether you want a calm, controlled follow-through or a snappy, dynamic shot reaction, your extension length and material can help fine-tune your bow to fit your style.

• Go shorter (or skip the extension) if you want a slower reaction or use heavy weight
  

• Go longer if you want more front-end reaction and use lighter stabilizer setups
  

• Pick aluminum for simplicity, strength, and value
  

• Pick carbon if feel, damping, and performance are top priority
  
  

As with any tuning component, your personal preferences and shooting style matter most. Try different setups, experiment with your bow's feel, and don’t be afraid to adjust over time as you grow as an archer.
