The Funk Motorsport L5D 6.6L Chevrolet Silverado HD 6500 Turbo Blanket is engineered to deliver advanced heat management for demanding diesel applications. Designed specifically for the Silverado HD 6500 fitted with the L5D 6.6L Duramax engine, this turbo blanket helps control under-bonnet temperatures, supporting both performance and component longevity in heavy-duty and high-performance environments.
This turbo blanket acts as a thermal barrier, wrapping tightly around the turbocharger’s turbine housing. By containing extreme heat within the turbo, it helps reduce radiant heat transfer to surrounding engine bay components. This containment supports lower intake temperatures, protects sensitive wiring and hoses, and can contribute to improved turbo efficiency and reliability—especially under sustained load or towing conditions.
The Funk Motorsport turbo blanket is ideal for Silverado HD 6500 owners who:
This upgrade is especially valuable for commercial, off-road, and expedition vehicles where reliability and heat management are critical.
Funk Motorsport’s signature 4-layer construction provides up to three times more thermal protection than many competitor blankets. The materials are selected for durability and heat resistance, supporting reliable performance in harsh engine bay conditions. The blanket’s removable design is a world-first, allowing for routine turbo maintenance without compromising fit or protection.
This turbo blanket is designed for a precise fit on the L5D 6.6L turbocharger found in the Chevrolet Silverado HD 6500. Installation is straightforward for experienced technicians or competent DIY enthusiasts, but always ensure the turbo is cool before fitting or removing the blanket. Routine inspection is recommended to maintain optimal thermal protection and blanket integrity, especially after extended heavy use.

It helps contain turbo heat, reducing engine bay temperatures and protecting nearby components from heat damage, which can improve reliability and turbo performance.
This specific blanket is designed for the L5D 6.6L Duramax turbocharger found in the Silverado HD 6500. Compatibility with other models or engine variants is not confirmed.
Installation can be performed by experienced DIYers or professional technicians. Ensure the turbo is completely cool before fitting or removing the blanket.
Routine inspection is recommended, especially after prolonged heavy use or exposure to harsh conditions. Replace if any damage or excessive wear is observed.
All finishes provide the same thermal protection; the choice is primarily aesthetic or based on your build preferences.
The removable design allows for easy access to the turbocharger for maintenance without damaging the blanket, supporting ongoing serviceability.
Check dimensions, mounting points, clearance and any wiring or hose requirements against your setup before ordering.
Send us your vehicle, year, current setup and any fitting date, event, trip or deadline before ordering. We will help check fitment, product choice and timing.
