    NOT COMPATIBLE WITH TORQUEMASTER OR TORSION SPRING SYSTEMS. ONLY EXTENSION SPRINGS!

    When looking to replace the extension springs on your garage door, it's important to ensure that you have the right size for the weight and height of your door. For example, if your garage door weighs 100lbs, you will need two 100lb extension springs to lift it. Before purchasing, be sure to get accurate height and weight measurements for your door.

    We recommend replacing not only the extension springs but also the pulleys and cables at the same time. This will guarantee that all the components are evenly balanced and prevent the need for future replacements. Over time, extension springs can stretch and become fatigued which can lead to problems if only one is replaced. By replacing all the parts of the extension spring system, you can ensure smooth and safe operation of your garage door.

    To ensure you get the job done right the first time you can purchase all the extension spring accessories like the clevis strap fastener, pulley kit and cables on our store. This will ensure that you have all the necessary parts for the replacement and make the process smooth and headache free.

    It's also worth noting that this pulley is specifically designed for garage door extension spring systems and is not compatible with torsion or torquemaster spring systems. To ensure you have all the necessary parts for the replacement, you can purchase the compatible hardware kit for a set of pulleys separately.

    Garage door extension spring pulley replacement is an important task that should be done carefully while using the proper tools and instructions. Remember to always replace all springs, pulleys and cables at the same time. Always pay attention to the compatibility of the pulley and other parts with the spring system you have.
