I’ve bought torsion springs here twice now. Once for my home back 6 yrs ago. This time was for my brother. The price has been the most competitive so far, even recently by 50%. I got two springs for the price of one at other quoted places. The one’s I’ve had at home for about 6 years now. They work great. Make sure you know what you are ordering.(from the inside looking out) The left side is RW(right widning) with a red color at the end and the right side is LW(right winding) likely painted black. The staff are pretty cool.
