The Bilstein B3 OE replacement coil spring restores factory suspension function for Mercedes-Benz C230 (2002–2005) rear applications by matching original dimensions and spring rates to recover correct ride height and handling. Constructed from high-quality chrome vanadium or chrome silicon steel, these springs use pigtail ends, minibloc and central force designs and are hot-set after forming to resist breakage and prevent height loss.
