Garage Door Extension Springs

When your garage door has to be raised too high to support your garage door opener, you do not have to buy an entirely new electric opener. You can save money by simply purchasing garage door extension spring replacements and cables. The extension cables allow you to raise the garage door to heights of 7 feet or 8 feet, or you can buy full extension springs for garage doors that range in height from 78 in. to 84 in. The lightest of these springs supports balance weights of 50 lbs., while the strongest of them supports balance weights of 250 lbs.

In addition to cables and springs, you can also purchase any supporting hardware that may be required. Cable pulley wheels are very inexpensive, and if you don’t know how heavy your garage door is, you may need a counter balance lever arm to weigh it.

If you have any questions about our garage door stretch springs, or how to order online, please give us a call at 877-226-2676 or email us. We’re happy to help! In stock, same day shipping available!
