Heavy Duty Silicone Coolant Hose Kit | 2006-2010 Chevy Silverado & GMC Sierra 6.6L Duramax
Replace your aging, failure-prone factory coolant hoses with the Mammoth Performance Heavy Duty Silicone Coolant Hose Kit—built to deliver superior durability, heat resistance, and peace of mind for your LBZ and LMM Duramax.
Stop Coolant Leaks Before They Start
The original rubber coolant hoses on your 2006-2010 6.6L Duramax degrade from years of heat cycling, pressure, and exposure to coolant chemicals. As they age, they swell, soften, 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 provide 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
Available in Multiple Colors – Add a clean, custom finish to your engine bay
Fitment
This kit is specifically designed for:
2006-2010 Chevrolet Silverado 2500/3500 6.6L Duramax

Covers LBZ (2006-2007) and LMM (2007.5-2010) engines
