Helper springs are specifically designed to have a minimal effect on the spring rate of the main coilover spring. Helper springs allow the spring to stay on mounted on the coilover perch when the shock is under negative or zero load, also known as droop travel. It is ideal to run helper springs on setups where you cannot preload the main spring due to height issues or when experiencing springs coming loose from the coilover perch.
About Swift Springs
Swift springs were founded back in 1997 in Tokyo, Japan, lead by former racer and suspension expert, Kei Yokota and chief engineer, Yasu Saito.
Developed as the next generation of suspension coil springs, their superior engineering, lightweight form, and ability to exhibit the most linear characteristics soon allowed Swift's involvement in motorsport to propel them through the ranks of some of the world's most reputable races. Swift springs are now recognised as one of the most respected names in performance coil springs and are still to this day used by championship teams for the Le Mans 24hrs, Super GT (JGTC), and many more.
