Swift Sport Mach Springs are manufactured with a unique spring compound H5S.TW. This super-strong material requires a double shot peening process to keep the spring's shape. The result is a high tensile strength spring requiring fewer coils than other brands, reducing overall weight. Springs are preset to reduce sag experienced after installation and given a 2-stage melamine coating providing an attractive layer of protection before final shipping to the U.S.
