Heavy Duty Silicone Coolant Hose Kit – Black | 2011-2016 Chevy Silverado & GMC Sierra 6.6L Duramax
Upgrade your LML Duramax with the Mammoth Performance Heavy Duty Silicone Coolant Hose Kit in sleek black—engineered to outlast and outperform the factory rubber hoses that swell, crack, and leak over time.
Stop Coolant Leaks Before They Start
The original rubber coolant hoses on your 2011-2016 6.6L Duramax break down from years of heat cycling, pressure, and coolant exposure. As they age, they soften, swell, and crack—leading to leaks, overheating, and the risk of being stranded. Our multi-ply silicone hoses are engineered to resist these failure modes and deliver a permanent upgrade that outlasts the truck itself.
Multi-Ply Silicone Construction – Reinforced with high-strength fabric layers to handle extreme temperatures, pressure, and vibration far better than OEM rubber
Superior Heat Resistance – Engineered to withstand the high under-hood and coolant temperatures of the hard-working Duramax diesel
Won't Crack, Swell, or Degrade – Silicone resists the breakdown that destroys factory rubber hoses over time
Direct OEM Fit – Designed to match factory routing and connections for a precise install with no modifications
Clean Black Finish – A subtle, factory-style look that complements any engine bay
Fitment
This kit is specifically designed for:
2011-2016 Chevrolet Silverado 2500/3500 6.6L Duramax
2011-2016 GMC Sierra 2500/3500 6.6L Duramax
Fits the LML (2011-2016) engine
What's Included
Complete set of reinforced black silicone coolant hoses
Stainless steel clamps for a secure, leak-free seal
Upgrade With Confidence
Whether you're towing heavy, putting down serious miles, or simply replacing tired factory hoses before they fail, the Mammoth Performance Silicone Coolant Hose Kit is the long-lasting, reliable solution your Duramax deserves.
