The whole variety
VOGTLAND sport springs are produced using special oil tempered spring steels of high tensile strength chromesilicon (CrSi) and chrome-silicon-vanadium (CrSiV) alloys using the cold coiling process. This provides reduced spring weight with high material strength, effectively reducing the unsprung weight of the vehicle and optimizing handling characteristics.
After the cold coiling process, all suspension springs are tempered, shotpeened and preset to ensure consistent vehicle ride height and suspension function.Low grade products will lose height due to high impact; however, VOGLAND springs are guaranteed to maintain their factory settings because of our sophisticated presetting program. Finally the springs are phosphated and powder coated to ensure a superior corrosion barrier for years of service.
