Does garage door torsion spring length matter?
Replacing a too-big or too-small torsion spring with the right size will balance the door and make it safe again. The door will rise with less effort and remain safely in place. The garage door opener may also need to be replaced if it has been damaged by springs that are too big or too small.

Why does my garage door have 2 different size torsion springs?
