Hyperco 3″ I.D. x 16″ Free Length Coilover Springs — E Series

Hyperco high-performance E-series coilover springs in a 3″ (76.2 mm) inside diameter and 16″ (406.4 mm) free length. Precision cold-wound from high-tensile chrome-silicon wire, heat-treated, preset and 100% rate-tested, so the printed rate is the delivered rate. Lighter weight and more usable deflection than comparable springs, and made in the USA.
Select your spring rate from the drop-down. Every spring in this listing shares the same 3″ I.D. and 16″ free length; only the rate and its associated deflection, load and coil dimensions change. All dimensions are shown in both inches and millimeters.
