I bought these to work on a old garage with weak springs and it worked great. Even with only 1 spring installed, it made a enormous difference. It's well coated and looks like it will rust quite well. The loops are closed and fairly strong. It has good lifting power but isn't so tightly wound that you can't mount it. For the price, its very much worth it and makes renovating a garage door eminently worth it.

These are a little shorter than others which made installation difficult. But after three tries I got the right strength springs.

I have handmade heavy wooden garage doors. I think the old springs had begun to wear unevenly and needed to replace the pair, (always replace in pairs to keep the tension balanced). I like the price of these as the cost of a pair is less than some sellers charging for one piece. One thing to note is that these are made in China and do not follow the color coding scheme in the US where the different colors represent the different weights that the springs should support. Other than that, these were easy to install and after checking with many test cycles, work fine.

After 17 years of use, my garage door started having problem opening and closing. A closer examination revealed the existing springs had stretched out and were loose. This was my first time replacing the garage door springs, and it was not a simple job. However, with some DIY experiences, it wasn't too complicated to figure out. After the replacement, the garage door was back in action again with no more issue. The new springs looked a little thinner and less heavy-duty than the old ones, but they worked out fine.

This review applies only to extension springs. Best if you know the part number of the spring for an exact match. If you do not, you either make an educated guess of the door weight or weigh the door. If you do the latter, remember garage door is very heavy. Use pulleys to ease the door to the ground (because you will do that after removing the springs). Remove the old springs before weighing. When buying the springs, match weight of door to the spring rating. If a door is in the down position, use the pulleys to lift the door. When installing the springs, use a C-clamp or a vice grip to prevent the door from a free fall. Lastly you need extensive knowledge to do a proper job. When in doubt, hire a professional.

Why did you pick this product vs others?: These appear to be very good quality. I returned these because they were too small and ordered a heaver spring, but it was my fault in measuring the door weight. I ordered the heaver load version of these springs and and my door worked properly. ( NOTE: Most doors use a pulley that requires you to double the spring weight to compensate for the 2 to 1 pulley )
