Hyperco LOCKER SPRG-SPCL Detroit Rear End Locker Spring - 70 lbs

Spring has superior durability and replaces the stock spring in Ford 9" rear ends with Detroit Lockers. Hypercoils are manufactured from the highest quality chrome silicone steel and high tensile chrome silicone steel. 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 the design and materials used.
