This is another part that a shocking amount of people buy on the aftermarket. I've yet to see a reason to buy anything BUT the factory radiator hoses. Since these are OE, they are an exact fit at the radiator and engine side so there are no leaks caused by poor fit. If you've ever tried the aftermarket hoses, you understand what I mean.
Your original spring clamps are made to last the life of the truck, so I recommend re-using them if you still have home. If someone has replaced them with the screw type, order them with the spring clamp kit.
