The HPS Silicone Heater Hose Kit provides a high-performance replacement for OEM heater coolant hoses on vehicles equipped with 5.7L V8 or 6.1L SRT8 engines. Constructed from 3-ply reinforced high-temperature silicone, these hoses withstand extreme heat up to 350°F while maintaining flexibility and structural integrity, ensuring reliable performance under prolonged under-hood conditions. Precision-molded with factory-correct bends and curves, the hoses guarantee a direct-fit installation without modifications. The included 100% stainless steel non-perforated embossed clamps provide secure attachment without cutting or damaging the silicone, delivering long-lasting, leak-free performance. This kit prevents common issues such as cracking, collapsing, or leaking hoses, making it ideal for both daily driving and high-performance applications. Race-proven and engineered for durability, the HPS Silicone Heater Hose Kit ensures consistent and reliable operation of the vehicle’s heating system. Note: Silicone hoses have a higher water permeation rate than standard EPDM rubber hoses. Regular coolant level checks are recommended for daily use.
