A control arm (76) includes a first component (78) having a first perimeter, a second component (80) having a second perimeter (84), wherein the first and second components are cast and wherein the first and second components are welded at the first and second perimeters. A control arm (76) includes an upper component (78), a lower component (80), and a vertical component disposed between the upper (78) and lower components (80), wherein the vertical component is welded to the upper and lower components. A method of fabricating a control arm (76) includes casting a first component (78) having a first perimeter and a seat disposed on the first perimeter, casting a second component (80) having a base and a wall, and coupling the first component to the second component, wherein the wall is welded to the seat.
