Funk Motorsport Turbo Blanket for LML 6.6L GMC Sierra HD

Purpose-Built Turbo Heat Shield for GMC Sierra HD

The Funk Motorsport LML 6.6L GMC Sierra HD Turbo Blanket is engineered to deliver advanced heat management for the Duramax turbocharger platform. Designed specifically for the LML 6.6L engine in GMC Sierra HD models, this turbo blanket addresses the unique thermal demands of high-output diesel applications, supporting both performance and reliability in demanding environments.

How the Turbo Blanket Improves Turbocharger Operation

This turbo blanket insulates the turbocharger’s turbine housing, helping to contain extreme heat generated during operation. By reducing radiant heat transfer into the engine bay, it supports lower intake temperatures, protects nearby components, and helps maintain optimal turbo efficiency. The result is improved engine bay safety, greater component longevity, and more consistent performance under heavy load or towing conditions.

Application Scenarios: Who Needs This Turbo Blanket?

Owners of LML 6.6L GMC Sierra HD trucks who demand more from their vehicle—whether for towing, off-road, or performance use—will benefit from this upgrade. It is especially valuable for those running modified or tuned engines, where increased exhaust temperatures and under-bonnet heat can threaten reliability. This turbo blanket is also ideal for drivers seeking to protect wiring, hoses, and sensors from heat soak, or those looking to maximise turbocharger response and efficiency.
