New silicone radiator hoses for the 69 - 70 Cougar or Mustang with the 390 or 428CJ engine. The hoses are made with a sturdy black silicone, which will last longer than standard rubber hoses and has a higher burst pressure rating. Includes upper and lower radiator hose, and a bypass hose. To help enhance its performance, the lower hose is nylon-reinforced and comes with a stainless steel spring, which will keep this hose from collapsing and causing other problems.
