TH350/400 Polished Alum Flywheel Dust Cover

The TH350/400 Polished Aluminum Flywheel Dust Cover is an essential component for transmission builders and performance engine shops modernizing classic Chevrolet drivetrain builds. This Racing Power Co-Packaged cover seals the gap between your bellhousing and flywheel, preventing dirt, oil mist, and debris from contaminating the clutch assembly and transmission internals. Whether you're restoring a vintage muscle car, upgrading a street rod, or optimizing a competition engine, this dust cover protects critical drivetrain components from environmental contamination that can compromise shift quality and long-term reliability.

Engineered from high-grade polished aluminum, this flywheel dust cover offers both functional protection and a finished appearance under the bellhousing. The polished finish resists corrosion and maintains clarity for visual inspection without disassembly, while the lightweight aluminum construction adds negligible weight to the drivetrain. The cover's design accommodates both TH350 and TH400 transmission applications, making it versatile across multiple Chevrolet engine families and hot rod platforms. Proper sealing at the bellhousing interface prevents oil blow-by and airborne particulates from reaching friction surfaces, directly contributing to extended clutch life and smoother engagement feel during street and track driving.

Mechanics and enthusiasts installing performance transmissions, turbo kits, or fresh short-block assemblies will find this dust cover indispensable for a professional-grade final product. It fits seamlessly into Chevrolet small-block and big-block configurations using Muncie, Saginaw, or Turbo 350/400 transmissions, and serves as a finishing detail that separates show-quality restorations from standard rebuilds. Installation requires basic hand tools and typically takes under 15 minutes; simply position the cover against the bellhousing and secure with the factory mounting points. This component is particularly valuable in high-heat environments, supercharged builds, or long-duration road racing where interior engine bay temperatures spike and contamination risk increases significantly.
