Our take on the 90 lb. Garage Door Extension Spring- 8' Door

This is a single extension spring for an 8-foot-high sectional garage door, rated at 90 lb of pull and coded light blue to Dasma standards. It uses high-quality spring wire, has double-looped ends and a 0.88 in inside diameter, and stretches from 27 to 48 inches. It is rated for a minimum of 10,000 cycles, which is the entry-level life span for extension springs; heavier-duty springs and torsion conversions last longer. It suits a do-it-yourselfer replacing a matched pair on a standard 8-foot door, and buyers should replace both springs at once and add safety cables.

Best forOwners of an 8-foot-high garage door replacing worn extension springsDo-it-yourselfers matching a light blue Dasma color codeBudget repairs where a 10,000-cycle rating is acceptable
Pros
  • Correct 90 lb rating for many single-car 8-foot doors
  • Dasma light blue color code makes weight matching simple
  • Double-looped ends for standard extension spring mounting
  • Rated for at least 10,000 cycles
  • 0.88 in inside diameter fits common extension spring hardware
Cons
  • 10,000 cycles is a low rating versus heavy-duty springs
  • Sold as one spring, so a pair must be bought for a proper replacement
  • No safety cables included, which extension springs should always have
  • Only fits 8-foot doors; wrong for 7-foot or taller doors

Questions and answers

How do I know this spring fits my door?
It is made for an 8-foot-high garage door and rated at 90 lb of pull, coded light blue under the Dasma color system. Match that color code and weight to the spring you are replacing. A 7-foot door needs a different spring.
Should I replace both springs at once?
Yes. Springs on the same door wear at the same rate, so a new spring paired with an old one leaves the door unbalanced and the old spring likely to fail soon. Buy two.
Do I need safety cables with extension springs?
Yes. Extension springs can snap and fly, so run a safety cable through each spring along its length. This spring does not include cables, so add them if you do not have them.
How long will it last?
It is rated for a minimum of 10,000 cycles, roughly several years of normal daily opening and closing. Heavy-duty springs with higher cycle ratings last longer if you open the door often.
What are the stretch and size specs?
It stretches from 27 to 48 inches and has a 0.88 in inside diameter with double-looped ends. Check your door's track and hardware before ordering.
