Heavy Duty Silicone Intercooler & Coolant Hose Kit | 2006-2010 Chevy Silverado & GMC Sierra 6.6L Duramax
Complete your engine bay upgrade with the Mammoth Performance Heavy Duty Silicone Intercooler & Coolant Hose Kit—a full combo package engineered to replace the failure-prone factory rubber boots and hoses on your LBZ and LMM Duramax with multi-ply silicone built to last.
Two Critical Upgrades, One Complete Kit
The OEM intercooler boots and coolant hoses on your 2006-2010 6.6L Duramax weren't built for the long haul. Heat cycling, turbo boost pressure, and coolant chemical exposure cause the stock rubber to crack, swell, and blow off—leading to boost leaks, lost power, coolant leaks, and overheating. This combo kit replaces both systems at once with reinforced silicone, giving you stronger performance and lasting reliability in a single install.
Why Choose Mammoth Performance Silicone
Multi-Ply Silicone Construction – Reinforced with high-strength fabric layers to handle extreme heat, boost pressure, and vibration far better than OEM rubber
Maintains Boost Pressure – Intercooler boots eliminate leaks for stronger throttle response, better towing, and improved fuel efficiency
Superior Heat Resistance – Coolant hoses 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 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
