Our take on the Garage Door Extension Spring - 8 ft High Door - Double Loop

A single replacement extension spring for garage doors up to 8 ft tall, with double-loop ends and painted, color-coded spring wire rated for 10,000 cycles. It measures 27 inches of body length with 48 inches of stretch. It is sold one spring at a time, and the maker recommends replacing both springs together so the pair wears evenly. It suits a homeowner doing a like-for-like swap on an 8 ft door rather than someone upgrading to torsion springs, which last longer and lift more quietly.

Pros
  • Rated for 10,000 open-and-close cycles
  • Double-loop ends match common extension spring hardware
  • Painted wire resists corrosion
  • Color-coded so the right weight rating is easy to match
  • 27-inch body with 48-inch stretch fits standard 8 ft doors
Cons
  • Sold individually, so a pair needs two orders
  • Extension springs snap loudly and store more energy than torsion springs
  • No weight rating printed in the listing beyond the color code
  • 10,000 cycles is modest next to torsion spring life

About the Garage Door Extension Spring - 8 ft High Door - Double Loop

This is a garage door extension spring with double loop ends, made for doors up to 8 feet tall. It is painted and color coded. The wire is rated for 10,000 cycles, and one cycle is one open and close of the door.

The spring is sold individually. Order a quantity of 2 to get a pair. Replacing both extension springs at the same time gives the best life for the new spring.

To choose the right spring, you need the height and weight of your door. The color coding repeats every hundred pounds, so check the height, weight and color together if possible.

Questions and answers

Does one order include both springs?
No. Each spring is sold individually. Order two if you are replacing a pair, which the maker recommends.
Will it fit my 8 ft garage door?
It is designed for doors up to 8 ft tall, with a 27-inch body and 48 inches of stretch. Match the color code to your old spring to get the right weight rating.
How long should it last?
It is rated for 10,000 cycles, with one cycle being a single open and close. That is roughly several years of typical daily use.
Should I replace both springs at once?
Yes. Springs of the same age wear at the same rate, and a new spring paired with an old one leaves the door unbalanced.
Is this a torsion spring?
No. It is an extension spring that runs along the horizontal track above the door, with double-loop ends.
Can I install it myself?
Extension springs are under heavy tension. If you are not confident with the door clamped and the tension released safely, have a garage door technician do the swap.
