The HPS Silicone Radiator + Heater Hose Kit is a high-performance upgrade designed to replace factory rubber hoses with superior materials built for longevity and reliability. Manufactured from premium 3-ply reinforced silicone, these hoses are engineered to withstand extreme temperatures up to 350°F, maintaining consistent pressure and preventing heat-related degradation. Each hose is precision-molded with factory-correct bends and curves to ensure perfect fitment and optimal coolant flow. The included 100% stainless steel non-perforated embossed clamps offer secure attachment without cutting into the silicone surface, guaranteeing a long-lasting, leak-free connection. Ideal for performance upgrades or dependable replacements, this kit effectively addresses issues such as coolant leaks, cracking, and collapsing hoses—common in aging rubber components. Race-proven and street-tested, the HPS Silicone Radiator + Heater Hose Kit delivers both performance and protection under the toughest driving conditions. Note: Silicone hoses have a higher water permeation rate than EPDM rubber. For daily-driven vehicles, checking coolant levels regularly is recommended.
