Our take on the 100 lb. Garage Door Extension Spring- 8' Door

This is a single extension spring for an 8-foot-high garage door, rated at 100 lb with an 80 lb pull and a tan Dasma color code. It is built from spring wire with double-looped ends, a 0.973 in inside diameter and a 27 to 48 inch stretch, and it is rated for at least 10,000 cycles. That cycle rating is modest next to the 20,000-plus cycles many premium springs claim, so it suits budget repairs and lighter doors rather than high-use doors. It is a like-for-like replacement part, not an upgrade.

Questions and answers

Does this spring fit my 8 ft garage door?
It is made for 8 ft high doors and lists a 27 to 48 inch stretch. Check your door's weight and existing spring's color code before ordering.
What does the tan color code mean?
Tan is the Dasma color code for this 100 lb spring. Matching the code on your old spring is the simplest way to confirm the right replacement.
How long will it last?
It is rated for a minimum of 10,000 cycles. That is roughly several years of normal open-and-close use, less on a door opened many times a day.
Do I need one or two springs?
Most garage doors use two extension springs, one per side. This listing is a single spring, so check your setup before ordering.

Extension springs store heavy tension and can cause serious injury if released. Many owners hire a technician, especially if the door uses a safety cable setup.
