2017-2019 GM 6.6L Duramax Upper and Lower Silicone Radiator Hose Kit - Pacific Performance Engineering - 119020400

Factory coolant hoses are composed of plastic Tee junctions that are prone to cracking and leaking after heat cycled. This PPE silicone hose kit completely eliminates the Tee junctions - the lower radiator hose, coolant overflow hose, and heater hose are all molded into one single piece of durable 5-ply silicone, providing maximum protection against leaking and heat fatigue. The silicone material used in this kit is far more heat resistant than the factory rubber - making it a better choice for this high-heat environment.
The CNC machined billet aluminum adapter ensures easy, OEM-like fitment onto the radiator outlet. All connections are sealed with uniform-tension 304 stainless steel clamps.
