Replacement Garage Door Extension Springs – Safe, Smooth & Reliable Performance
Keep your garage door operating smoothly, safely, and efficiently with high-quality 53" x 72" garage door extension springs, designed for 12-foot residential garage doors. These springs provide essential counterbalance support, reducing strain on cables, rollers, and hardware while improving overall door performance and safety.
Extension springs are weight-rated as a pair, meaning both springs work together to support the total door weight. Always replace both springs at the same time to ensure proper balance and safe operation.
Important: Select the correct spring rating based on your garage door weight. Example: A 200 lb door requires a 200 lb rated pair of springs.
