Hyperco 1.875″ I.D. x 10″ Free Length Coilover Springs — D Series

Hyperco high-performance D-series coilover springs in a 1.875″ (47.6 mm) inside diameter and 10″ (254.0 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 1.875″ I.D. and 10″ free length; only the rate and its associated deflection, load and coil dimensions change.
