Fortune Auto teamed up with Swift springs to be our primary spring supplier on our high performance damper systems. We elected to use Swift springs as our primary supplier because of their advanced and proprietary magnetic steel alloy called HS5 TW, while all other spring manufacturers utilize a inferior silicone chrome steel alloy. There are many advantages to Swift’s magnetic steel alloy: (1) the HS5 TW alloy is faster reacting and more compliant then traditional spring alloys which translates into a more responsive and comfortable ride, (2) the magnetic steel alloy possesses lightweight property and less coils which means less un-sprung weight and more suspension stroke, (3) lastly Swift springs have been successfully used by top tier race teams all over the world including 24 Hours of Le Mans, Formula 1 and Super Taikyu Endurance racing. We also offer Hyperco springs to specific customers that prefer a high quality American made spring option for their Fortune Auto dampers.
