Swift Springs are arguably the best springs on the market. Swift makes their springs using a material they created called H5S.TW. This material is stronger than silicon chrome. So strong in fact that it needs 2 rounds of shot peening to hold it's shape. It also requires a thinner wire and less coils than other spring materials. This means that the end result is a lighter stronger spring. The other benefit of H5S.TW is that it is more consistent in spring rate than any other material and improved strength and durability. Out of the top three competing brands the longest that any one of them was able to last is 277,832 compressions without spring failure. The Swift spring was able to reach 1,000,000 compressions before the test was stopped in the interest of time, and it did so without any sign of failure or fatigue. This amazing spring material is patented by Swift and no other company has anything comparable with most still using silicon chrome.
