Mammoth Performance HD Coolant Hose Kit 06-10 GM 6.6L Duramax LLY/LBZ/LMM

Description

Keep your 6.6L Duramax cooling system ready for the long haul with the Mammoth Performance Heavy Duty Silicone Coolant Hose Kit. Years of heat cycles, coolant exposure, pressure, and vibration can cause factory rubber hoses to swell, soften, crack, and eventually leak, putting your truck at risk of overheating and an unexpected breakdown. This complete silicone hose kit replaces the aging factory components with a more durable solution designed for daily driving, heavy towing, and high-mileage Duramax applications. Constructed from multi-ply silicone reinforced with high-strength fabric layers, these hoses are built to withstand the heat, pressure, and vibration found in a hard-working Duramax cooling system while resisting the cracking, swelling, and deterioration common with aging rubber. The direct OEM-style design follows factory routing and connections for a straightforward installation with no modifications, while the included stainless steel clamps provide a secure, reliable seal.
