Abstract: A camshaft assembly configured to rotate about an axis of rotation within the engine of a motor vehicle to provide timing between cyclic operation of engine components is provided. The camshaft assembly includes a member for providing timing to a first engine component. The member includes a cam surface configured to drive the timing of the first engine component, and an opening. The camshaft assembly also includes a camshaft body cast to the member and configured to engage the opening of the member. The camshaft body includes a lobe configured to drive the timing of a second engine component, and a journal configured to allow efficient rotation of the camshaft body about the axis of rotation. The member is formed from a first material and the camshaft body is formed from a second material, thereby allowing the camshaft assembly to withstand two levels of stress.
