Ideal Security Garage Door Extension Springs are designed for standard 7' high garage doors. They provide additional lifting power for manual and electric garage doors. Our springs are original equipment quality, made to last for many years.
REPLACING YOUR SPRINGS
If your springs sag or are longer than 25" in the relaxed position, it may be time to replace them. It's important to always change your springs in pairs to maintain proper balance, and to always install safety cables .
Replacing garage door springs can be done yourself if you're comfortable, but may not be a task for everyone. Before buying, please watch our how-to videos to ensure you're comfortable doing the work yourself.
SPRING SELECTION: CAPACITIES AND COLORS
Garage door springs are color-coded to indicate weight capacity. Our springs follow industry-standard color coding. You should replace your springs with the same class of spring you currently have. You can use our handy Spring Selection Guide to ensure you choose the right springs for your door. Verify your current springs before ordering and installing. Some of our competitors use blue on both their 90lb and 140lb springs! If your current springs are blue, ensure that you know your door weight or spring diameter before ordering.
All our springs are 25" long relaxed and 67" when fully stretched.
