The invention discloses an automobile suspension component and a manufacturing method thereof. The method comprises the following steps: S1, preparing aluminum alloy raw materials, wherein the aluminum alloy raw materials comprise, by mass, 0.15%-0.22% of Fe, 1.25%-1.35% of Si, 0.82%-0.88% of Mn, 0.15%-0.2% of Cu, 0.85%-0.95% of Mg, 0.17%-0.25% of Cr, less than or equal to 0.06% of Ni, less than or equal to 0.6% of Zn, 0.05%-0.1% of Ti, 0.03%-0.05% of Zr, 0.18%-0.26% of Sn, 0.12%-0.29% of Li, 0.03%-0.09% of Co and the balance Al; S2, smelting the aluminum alloy raw materials to prepare aluminum alloy melt; S3, casting the aluminum alloy melt to prepare a prefabricated part; and S4, carrying out die forging on the prefabricated part to prepare a finished product. By improving the materials for preparing the aluminum alloy raw materials, the suspension strength and stability can be improved, meanwhile, the self weight of an automobile can be effectively reduced, the energy consumption of the automobile is reduced, and therefore energy conservation and emission reduction in the using process of the automobile are achieved.
