차량용 하이브리드 현가암은, 스틸 재질의 현가암 바디; 상기 현가암 바디에 인서트되어 결합되는 플라스틱 인서트 몰딩을 포함하고; 상기 현가암 바디에는 결합 플랜지가 형성되고; 상기 결합 플랜지는 상기 플라스틱 인서트 몰딩에 삽입되어 결합됨으로써, 저중량 및 고강성의 현가암을 제공할 수 있다. A hybrid lower arm and a hybrid upper arm include an arm body made of a metal material, and an insert injection-molded integrally with the arm body so that the insert is inserted into an inside of the arm body. The arm body has a weight ratio of 50% or more and 90% or less with respect to the total weight of the hybrid lower arm or the hybrid upper arm, thus achieving the rigidity increase as well as the weight reduction in the lower arm and the upper arm of a suspension system.
