If you have 2 springs,
we highly recommend that you replace both springs.

Avoid Having to Repeat The Replacement Process
If your door cycles (opens & Closes) more than 3 times a day, we recommend our High Cycle Option. An inexpensive upgrade that will double the spring cycle life from 10,000 up to 20,000 cycles.
What is a High Cycle Spring?
A high cycle spring is a re-engineered spring base on your existing spring measurements(See Steps 1 thru 4) creating a DIMENSIONALLY larger spring. A High Cycle spring has the same IPPT(Inch Pounds Per Turn) or torque as the existing spring but has 50% less stress when fully wound, lasting 2X longer. The installation and the number of turns are the same as the existing spring.
