So the poly ball can allow some rotation of the joint and the softer cups help keep grease in and dirt out. It's not all the same durometer (otherwise it would act like a solid block of poly).

MSRP: $196.52 plus freight. Sale price: $159.99 shipped (48 states of the US). (IMG:http://www.hotpart.com/shop/images/products/large_85_Camaro_Extreme_Joint_Lower_Control_Arm_-_1.jpg)
