What Types of Garage Door Springs Are There?
Before adjusting anything, you must identify the spring type.
Two Main Types:

👉 Important: Torsion springs are under extreme tension and require extra caution.
How Do You Adjust Spring Tension On A Garage Door (Step-by-Step)
⚠️ Safety Warning: If you’re unsure at any step, stop and call a professional. Improper handling can cause serious injury.
Step 1: Disconnect the Garage Door Opener
- Unplug the opener from power
- Pull the emergency release cord
- Ensure the door is fully closed
🔒 This prevents accidental movement during adjustment.
Step 2: Secure the Door
- Use C-clamps or locking pliers
- Attach them to the track just above a roller
✔️ This keeps the door from moving unexpectedly.
Step 3: Identify the Adjustment Direction
- If the door falls quickly, increase tension
- If the door won’t close, decrease tension
💡 Proper balance means the door stays in place when halfway open.
Step 4: Adjust Torsion Springs
Tools Needed:
- Winding bars (never use screwdrivers)
Steps:
- Insert winding bar into the winding cone
- Loosen set screws carefully
- Turn the spring:
- ¼ turn at a time
- Clockwise = increase tension
- Counterclockwise = decrease tension
- Tighten set screws securely
⚠️ Always keep a firm grip on the winding bar.
Step 5: Adjust Extension Springs
Steps:
- Move the hook to a different hole in the track hanger
- Higher hole = more tension
- Lower hole = less tension
✔️ Adjust both sides evenly to maintain balance.
Step 6: Test the Door Balance
- Remove clamps
- Manually lift the door halfway
Ideal Result:
- Door stays in place without moving
🔄 Repeat adjustments if needed.
How Do You Know If Spring Tension Is Correct?
Here’s a quick checklist:
