Funk Motorsport LBZ 6.6L GMC Sierra HD Turbo Blanket Overview
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.
How the Turbo Blanket Improves Your GMC Sierra HD
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.
Application Scenarios for the LBZ 6.6L Sierra HD Turbo Blanket
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:
Reducing engine bay heat during heavy towing or hauling
Protecting wiring, hoses, and plastics from heat damage
Supporting performance builds where intake temperatures must be controlled
Enhancing reliability for off-road and expedition vehicles
Allowing easier access for turbo maintenance thanks to its removable design
