Upgrade your Peterbilt 386’s cooling performance with the Kustom Truck Radiator and Charge Air Cooler Tube Kit, precision-engineered for 2008 and newer models equipped with Cummins ISX CM870 engine electronics. Crafted from premium 304 stainless steel in mill or polished finish, this OEM-quality kit includes right and left charge air cooler (CAC) tubes, plus upper and lower radiator tubes, ensuring efficient airflow and coolant flow with corrosion resistance. Tailored for engine conversions, it features precise configurations: the right CAC tube pairs with a 4" 90-degree turbo outlet elbow (Kustom Truck P/N 99202035 or similar), the left CAC tube aligns with a horizontal EGR intake manifold with an air inlet elbow at roughly 10 o'clock, the upper radiator tube fits a vertical-facing thermostat housing outlet requiring a 90-degree silicone elbow (Kustom Truck P/N 99907013 or similar), and the lower radiator tube matches a 2.5" water pump inlet, also requiring a 90-degree silicone elbow at the radiator outlet (Kustom Truck P/N 99907013 or similar). Ideal for mechanics and truck owners, this kit blends durability and style for heavy-duty diesel applications.
