.234 wire size with 2" inside diameter (ID). Torsion spring comes complete with stationary cone, winding cone, and set screws. Choose your appropriate length. This is an individual RIGHT WIND spring (goes on left side of door, marked RED).
Our garage door springs are oil-coated, made in the USA, and have been designed and tested to last 10,000 cycles or more. All springs come with a 1-Year Replacement Warranty to protect against defects (unlikely). If our spring breaks within 1 year of your purchase, we will provide a replacement spring for free.
If your garage door has two springs, it's likely the other spring is nearing the end of its life cycle as well. It's generally recommended that both springs be replaced when one breaks.
Important: Removing or installing torsion springs is dangerous. An accident can lead to serious injury or death. Install at your own risk. Never use anything besides winding bars to wind or unwind springs. Please consult a professional if needed.
