In this paper, the design optimization and fabrication process of Aluminium cast for Lower Control Arm (LCA) were investigated. The aluminum lightweight front lower control arm will be developed using casting processing route and its performance will be investigated to determine the mechanical properties of the parts. In this work, the new concept design of cast lower arm are employed. Then, the topology optimization process is conducted to get the optimized shape based on target 20% weight reduction. The final optimized design is evaluated with structural strength analysis to analyze component performance in a vehicle. The parts that produced is expected to have a lightweight, high strength and good corrosion resistance and suitable for  current vehicle performance.
