Product May Differ From Photo
Hyper coils are manufactured from the highest quality chrome silicone steel and high tensile chrome silicone steel available in the world. The material used in producing Hyper coils 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.
