The LB7 Duramax earned its reputation for torque -- and its factory rubber intercooler boots earned a reputation for failing under it. Heat, oil vapor, and 20+ years of boost pressure turn the OEM rubber soft and swollen until a boot blows off mid-pull. This 5-Ply Silicone CAC Intercooler Boot Kit replaces every rubber charge air connector with heavy-duty 5-ply silicone -- thicker walls, stronger fabric ply, no ballooning.

Key Points:

• 5-ply reinforced silicone, heavier-duty than standard 3 or 4-ply
• Oil-resistant inner liner, internal fabric ply prevents ballooning
• Full kit replaces all factory rubber CAC boots and intercooler connectors
• Direct OEM fitment, factory clamp positions, no trimming
• Handles stock and tuned boost levels on the LB7
