RideTech 59070400 Coil Spring, 7" Length, 400 Lbs/In, 2.5" ID

When it comes to coil springs for Coil-overs, Ridetech supplies Hyperco Hypercoils exclusively. Hypercoil coil springs are manufactured from high tensile chrome silicon steel the highest grade spring material available. The high tensile steel wire used in Hypercoils is lighter and allows additional travel before reaching coil-bind. Hyperco’s advanced engineering produces coil springs that achieve the same length and rate with fewer coils than other brands. In many cases, Hypercoils use three less coils and smaller diameter wire (.480? vs. .510?). This allows for an additional compression of the spring which equates to better travel. During the manufacturing process, Hypercoils undergo two separate Magnaflux inspections to ensure that all coil springs are free from surface imperfections that might lead to early failure. Hyperco employs a unique combination of state-of-the-art CNC equipment along with small town craftsmanship to produce the finest coil springs available anywhere in the world.
