Hypercoils 13" Rear Coil Spring - 5" O.D. - 175 lb. Clutch Pressure Plate Made from high-silicon ductile ironHypercoils are manufactured from the highest quality chrome silicone steel and high tensile chrome silicone steel available in the world. The material used in producing Hypercoils undergoes two separate magnaflux inspections. Once before manufacture and again after coiling. These inspections insure the wire is free from surface imperfections which, if gone undetected could lead to spring failure. The life of a suspension coil is directly related to
