Think of your garage door springs like the counterweight in an old elevator. Without them, your door would be incredibly difficult to lift manually, and your garage door opener would burn out trying to handle all that weight on its own.
Here's something that surprises a lot of people: there are usually several different spring combinations that will work for your 16x7 door. You might be able to use a single heavy-duty spring or two lighter springs, depending on your setup and preferences.
Don't get caught up in the "stronger is better" mindset when it comes to garage door springs. Focus on getting the correct spring instead. Your door will work smoother, last longer, and save you headaches down the road.
