All DURA-LIFT® torsion springs are manufactured from Class 2 high-tensile, oil-tempered spring wire, meeting ASTM A229. Made from USA wire and coiled in the USA, all torsion spring wire is coated for improved corrosion resistance and easier handling. Both 10,000 "standard" cycle and 25,000 "high-cycle" springs are available in left or right wind, and in precut or longer lengths. Click here for standard cycle to high-cycle spring conversions.
Torsion springs are designed to carry a specific weight and should be replaced with springs of the same size and wire gauge. Learn how to use your old torsion springs to figure out which springs to buy.
We recommend having a professional change your torsion springs. However, if you feel comfortable doing so yourself, make sure to carefully follow all instructions and safety precautions outlined in the tutorial, and use the proper tools.
