How to Convert Extension Spring to Torsion?: Step-by-Step Guide

When it comes to garage door systems, converting from extension springs to torsion springs can offer several benefits. This comprehensive guide will take you through the step-by-step process of converting your garage door’s spring system, providing you with the knowledge and confidence to tackle the task.

Extension springs and torsion springs are two common types of garage door springs, each with its own characteristics and advantages. Understanding these differences is crucial before proceeding with the conversion.

Extension Springs:

Extension springs work by stretching and contracting as the door opens and closes. They are typically found on both sides of the garage door, parallel to the horizontal tracks. Extension springs provide a counterbalance to the weight of the door, enabling smooth operation.

Torsion Springs:

Torsion springs, on the other hand, operate by twisting and releasing energy to lift and lower the door. They are usually mounted above the garage door opening, parallel to the header. Torsion springs offer improved balance, durability, and overall performance compared to extension springs.

Tools and Materials Needed:

Before you embark on the conversion process, gather the necessary tools and materials to ensure a smooth and successful project.


  1. Adjustable wrench
  2. Vice grips
  3. C-clamps
  4. Tape measure
  5. Drill
  6. Screwdriver
  7. Safety glasses
  8. Gloves


  1. Torsion spring assembly kit (specific to your door size and weight)
  2. Garage door opener reinforcement bracket (if required)
  3. Ladder
  4. Lubricant (for maintaining the new torsion springs)

By having these tools and materials ready, you’ll be well-prepared to proceed with the conversion process confidently.

Remember, the conversion from extension springs to torsion springs can be complex and potentially dangerous if not done correctly. It is crucial to follow safety guidelines, take necessary precautions, and consider seeking professional assistance if you are unsure about any aspect of the process.

Stay tuned for the next sections of this guide, where we will delve into the step-by-step instructions for converting your garage door’s spring system from extension springs to torsion springs.

Step-by-Step Guide to Convert Extension Spring to Torsion:

Follow these step-by-step instructions to successfully convert your garage door from extension springs to torsion springs:

  1. Measure and order the correct torsion spring setup based on your garage door’s weight and size.
  2. Disconnect and remove the existing extension springs, ensuring the door is securely supported.
  3. Install the torsion spring assembly above the door, following the manufacturer’s instructions.
  4. Adjust the tension of the torsion springs using winding bars and the proper technique.
  5. Balance the door by adjusting the torsion spring tension on each side, achieving smooth operation.
  6. Test the door’s functionality by manually opening and closing it, ensuring it moves smoothly and stays in place.
  7. Fine-tune the tension and balance as needed until the door operates optimally.

Remember, converting from extension springs to torsion springs requires precision and care. If you are uncertain or uncomfortable with any step, it is recommended to consult a professional garage door technician who can assist you safely.

Safety Considerations and Professional Assistance:

Safety is paramount when working with garage door springs.

Emphasize the following safety considerations throughout the conversion process:

  1. Wear safety glasses and gloves to protect your eyes and hands from potential injury.
  2. Use proper tools and techniques to avoid accidents or mishaps.
  3. Always disconnect the power to the garage door opener before starting any work.
  4. Be cautious of the high tension stored in torsion springs and handle them with care.
  5. If you encounter any difficulties or uncertainties during the conversion, it is wise to seek professional assistance.

Discuss when it may be necessary to seek professional assistance for the conversion:

  1. If you lack the necessary tools or experience to safely complete the conversion.
  2. If your garage door has specific complexities or unique configurations that require professional knowledge.
  3. If you have any concerns about your ability to correctly adjust and balance the torsion springs.


Summarize the key points of the guide and highlight the benefits of converting from extension springs to torsion springs. These benefits may include improved door balance, smoother operation, and increased durability.

Encourage readers to carefully consider their specific needs, skill level, and comfort with DIY projects before attempting the conversion. Stress the importance of prioritizing safety at all times and the option to seek professional assistance if needed.

By following this step-by-step guide and taking the necessary precautions, you can successfully convert your garage door from extension springs to torsion springs, enjoying the advantages that come with this upgrade.
