This page provides links to what I believe to be the best deal on garage door springs, openers, and other parts.

Buying torsion springs can be a hassle as most sellers carry a random selection.  To make it easier I have linked to reputable online sellers that carry the greatest possible variety.  If you can’t find an exact match use this chart to find a different spring of the same strength.
