TH350/TH400 Bellhousing Kit Aluminum - SFI

The TH350/TH400 Bellhousing Kit Aluminum - SFI is a vital structural component designed for high-performance Chevy V8 applications. Engineered by FTI Performance, this bellhousing serves as the primary connection between a Chevrolet small block or big block engine and a Turbo-Hydramatic 350 or 400 transmission. When building a vehicle for competitive drag racing or high-torque street use, ensuring proper fitment and safety is paramount to maintaining drivetrain alignment and operator protection.

Safety is the core focus of the SFI 30.1 certification included with this unit. This rating indicates that the bellhousing has been tested to meet specific structural standards required by major racing sanctioning bodies, such as the NHRA and IHRA. In the event of a mechanical failure involving the torque converter or flexplate, this aluminum bellhousing is designed to contain debris, significantly reducing the risk of injury or additional vehicle damage. This makes it a required specification for many competitive racing classes where high RPMs and heavy loads are common.

Constructed from premium aluminum with a natural finish, this kit provides a lightweight yet rigid alternative to heavy cast iron factory housings. The reduction in weight helps improve overall vehicle balance without sacrificing the durability needed to handle the output of a performance Chevy V8. Before you buy, consider that this kit is designed for builders who prioritize precision; it ensures that the transmission remains perfectly centered, which is critical for preventing premature wear on the front pump and input shaft during hard launches.

Reviewing the technical specifications reveals a product optimized for versatility. Whether you are performing a transmission swap or upgrading an existing TH350 or TH400 setup, the FTI Performance F1042 provides the necessary hardware and structural integrity for a professional-grade installation. This kit represents an essential investment for any enthusiast looking to combine the reliability of classic GM transmissions with modern safety standards and performance-grade materials.
