The Funk Motorsport LLY 6.6L Chevrolet Silverado HD Turbo Blanket is purpose-built for 2004.5–2006 Duramax LLY-equipped Silverado HD trucks. Designed to address the unique heat management challenges of high-output turbo diesels, this advanced turbo blanket helps protect your engine bay from excessive radiant heat while supporting turbocharger efficiency and long-term reliability.
Turbochargers generate extreme heat, especially under load or when towing. Without proper insulation, this heat can soak into wiring, hoses, and surrounding components, leading to premature wear and reduced reliability. The Funk Motorsport turbo blanket wraps the turbine housing, trapping heat inside the turbo and minimising transfer to the engine bay. This helps maintain optimal turbo spool, supports consistent performance, and reduces the risk of heat-related failures.
This turbo blanket is ideal for:
If you rely on your Silverado HD for demanding work or performance, this turbo blanket delivers practical, proven heat management benefits.
Choose from three finishes to match your build and environment:
All finishes deliver the same high level of thermal protection; selection is based on your visual preference and installation needs.
This turbo blanket is tailored for the LLY 6.6L Duramax turbo found in 2004.5–2006 Silverado HDs, ensuring a secure and precise fit.
