Manufactured to OE specifications with high‑quality chrome vanadium or chrome silicon steel and hot‑setting after forming to prevent height loss, these springs use technical shapes such as pigtail ends and minibloc designs to improve break resistance and maintain suspension function and safety to factory standards.
