The Funk Motorsport LBZ 6.6L GMC Sierra HD Turbo Blanket is designed specifically for the Duramax-powered Sierra HD platform, providing advanced turbo heat management for demanding road, off-road, and towing applications. Engineered with Funk Motorsport’s signature four-layer construction, this turbo blanket delivers robust thermal protection to help control under-bonnet temperatures and support turbocharger efficiency.
This turbo blanket is tailored to fit the LBZ 6.6L Duramax turbocharger, helping to contain extreme heat produced by the turbine housing. By reducing radiant heat in the engine bay, it protects sensitive components, minimises heat soak, and helps maintain consistent intake temperatures. The result is improved reliability, enhanced performance, and greater confidence during heavy-duty use or spirited driving.
Owners of GMC Sierra HD trucks equipped with the LBZ 6.6L Duramax engine often face challenges with engine bay heat, especially during towing, off-road work, or performance upgrades. This turbo blanket is ideal for:
