When it comes to garage door extension spring systems, it's important to remember that two springs are required to lift the weight of the door. For example, if you have a 80lb garage door, you will need two 80lb extension springs to lift it. When looking to replace your garage door extension springs, it's important to check the item description for information on size, life cycle and other specific details.
We recommend that you replace both springs, pulleys, and cables at the same time to ensure they are evenly balanced and to not have to do it again. Over time, extension springs can stretch and become fatigued which can cause problems if only one is replaced. By replacing both at the same time, and all of the extension spring cables and pulleys you can avoid issues related to an uneven balance.
To make the process even more convenient, you can get a garage door extension spring ,clevis strap fastener kit, pulley kit, and cables. Replacing all these parts will ensure a smooth, safe operation of your garage door.
In addition, it's worth noting that this pulley is specifically designed for garage door extension spring systems and is not compatible with torsion or torquemaster spring systems. And to make sure you have all the necessary parts for the replacement, you can purchase the compatible hardware kit for a set of pulleys separately.
In summary, garage door extension spring pulley replacement is an important task that should be done with great care, make sure to always replace both springs at the same time, and use a garage door extension spring and pulley kit to make the process smooth, and always pay attention to the compatibility of the pulley with the spring system you have.
