Review: These appear to be very good quality. - 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 )
Review: Solid replacement springs - 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.

## Features

## Questions & Answers

**Q: What is the length of these springs?**
A: The retracted length is 26 1/2 inches, tip to tip.  I would imagine that is the standard length of all such garage door springs, but not sure.  The important thing when ordering is to get the correct springs for your door weight.  My old springs were green on the end, so that told me that they were 120 lb. springs and that is what I ordered for replacements.

**Q: What is the outside diameter of the springs?**
A: The outside diameter is 1.73inch

**Q: How far is the extended length of the springs**
A: 68 inches fully extended, garage door down..

**Q: Other manufacturers have a 1.5 outer diameter for 140lbs 7ft doors, is this ok or is it supposed to be standardized ?**
A: shouldn't be a problem on a alum,door

### ⭐⭐⭐⭐⭐ Heavy duty
*by H***R on April 1, 2025*

Strong spring. Set up easy.. just leave slack to hook on. Important make sure to get some color match to your door spring. To heavy or to light won't work and could damage door.
