LT4 Supercharger Lid Black

The Billet Specialties LT4 Supercharger Lid in black anodized aluminum is a direct replacement component designed for GM's Gen V LT-series engines. This precision-machined supercharger cover delivers both functional protection and a refined appearance, engineered to match OEM specifications while accommodating high-performance modifications. The black anodized finish resists corrosion and maintains its appearance through repeated heat cycling and engine bay exposure.

Constructed from aluminum, this lid provides a lightweight alternative to stock components while maintaining structural integrity under boost conditions. The black anodized coating creates a hard, durable surface that protects the underlying aluminum from oxidation and UV degradation—critical for engine bay environments where temperature swings and moisture exposure occur daily. At 14 pounds, the weight is optimized to minimize rotational mass without compromising rigidity. Dimensionally accurate at 18 x 3.75 x 18 inches, it integrates seamlessly with LT-series supercharger assemblies.

This replacement is essential for LT4-equipped vehicles undergoing supercharger maintenance, repair, or aesthetic upgrades. Whether restoring a stock appearance after component inspection, replacing a damaged lid, or upgrading to a higher-quality finish, this Billet Specialties cover meets the exacting standards expected in modern LS/LT platforms. The LT4 designation confirms compatibility with Corvette C7, Camaro ZL1, and other Gen V LT4-powered vehicles where OEM fitment and durability are non-negotiable.
