These springs did the job, and came with a new plastic bushing and the lever rods needed to tension the springs. However, this is a complicated task, and potentially dangerous. Look up DDM Garage Doors, he has detailed instructions and safety info, and a video. Read it all carefully, and watch the video. He explains how to measure your old spring or springs, so that you order the correct replacement. This is not simple, you have to measure the length, inside diameter of the coiled spring, and the diameter of the wire the spring is made of. If you have two springs as I did, with one broken, you have to measure both as they aren't necessarily the same. Also, the good spring being tensioned, is longer than it would be if untensioned, and he explains how to calculate the untensioned length which is what you need to order. I had to wind each new spring 30 quarter turns, which is the dangerous part, you are storing a lot of energy in those springs so do it very carefully. You can take a break by letting the rod rest against the door. I followed the directions carefully, used my laptop to watch/pause the video at each step. I had my wife help by counting the turns, handing me tools, and reminding me to stretch the springs after tensioning but before tightening the set bolts. I got it all done, and lifted the door- it was perfect. It was easy to lift and stayed up, down, or in between, wherever I left it.
