These 2.5\" ID Swift barrel coilover springs are manufactured in Japan from proprietary H5S.TW high-tensile alloy steel, eliminating spring bowing and rate inconsistency while delivering the traction and weight transfer characteristics that competitive racers depend on.\u003c\/p\u003e\n\u003cp\u003eFor over 90 years, Swift Springs has led the industry in precision spring manufacturing. The barrel design prevents spring-to-shock-body contact that damages adjusting perch threads, while H5S.TW alloy delivers superior fatigue resistance and rate consistency lap after lap. Swift Springs coilover springs provide increased traction, smoother weight transfer, lower tire temperatures, and a more predictable driving experience.\u003c\/p\u003e\n\u003ch3\u003eWhy Racers Choose Swift Springs Coilover Springs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProprietary H5S.TW alloy delivers superior fatigue resistance and consistent spring rates\u003c\/li\u003e\n\u003cli\u003eBarrel design eliminates spring deflection, bowing, and shock body contact\u003c\/li\u003e\n\u003cli\u003eFewer coils reduce unsprung weight and maximize usable shock stroke\u003c\/li\u003e\n\u003cli\u003eQuicker transient response improves traction and road surface tracking\u003c\/li\u003e\n\u003cli\u003ePrecision-ground flat ends ensure even seating on the perch\u003c\/li\u003e\n\u003cli\u003eTrusted by professional racing teams worldwide — Swift Springs coilover springs are proven in competitive motorsport\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Swift Coilover Springs are sold individually.
