HPS Performance Products 57-1327R-BLK High Temp Reinforced Silicone Radiator Hose Kit - 3-Ply Black

The HPS Performance Products 57-1327R-BLK is a high temperature, 3-ply reinforced silicone radiator hose kit engineered as a direct-fit upgrade over stock OEM rubber coolant hoses. Built to meet or exceed OE specifications, this kit delivers superior heat resistance and long-term durability in demanding under-hood environments.

OEM rubber radiator hoses are prone to hardening, cracking, and collapsing over time — leading to coolant leaks and engine overheating. The HPS silicone hoses are precision-formed with the correct bends and curves for a perfect, no-modification-required fitment, making installation straightforward and hassle-free.

Key Features:

• Premium 3-ply reinforced silicone construction for maximum strength and heat resistance
• Rated to withstand temperatures up to 350°F (177°C) and prolonged exposure to under-hood and coolant heat
• Meets or exceeds OE specifications — a true performance upgrade over stock rubber hoses
• Precision-molded with correct bends and curves for direct, no-modification fitment
• Includes 100% stainless steel non-perforated embossed hose clamps that will not cut through the silicone hose material
• Replaces OEM part numbers: 5039678AB and 5039789AA
• Available in Black, Blue, and Red
• Backed by a 2-year warranty

Important Note: Silicone hoses have a water permeation rate 10–15 times greater than standard EPDM rubber hoses. Regular coolant level checks are strongly recommended when silicone coolant hoses are used in daily-driven vehicles.
