Torsion springs provide over 90% of the lift needed to raise your garage door. Quality springs ensure a longer life for your garage door operator. Precision Garage Door uses heavy duty high-cycle springs that do not require lubrication and will not rust! The premium quality ASTM A229 grade, class II, oil tempered wire has a weather resistant coating with a baked gloss finish. They last over 4 times as long as normal springs and are designed to do their job for years to come.
