Important Note: 

For optimal performance and safety, replace springs in pairs. Replacing only one spring can cause unequal pull, leading to damage to your door and opener, and posing safety risks. Both springs typically wear out together, so it's best to replace them simultaneously to ensure even lifting and avoid issues like binding or track misalignment.
