The CSR Performance TH400 Flexplate & Trans Ultrashield is a SFI 4.1–rated automatic transmission shield engineered to protect modern TH400 transmissions from heat damage, debris, and impact during high-performance driving. This composite shield assembly combines proven thermal protection with lightweight construction, making it an essential upgrade for street machines, drag cars, and any vehicle running a built TH400 transmission where transmission longevity matters.
Constructed from composite material in a professional black finish, this shield kit addresses a critical vulnerability in high-output TH400 builds. The SFI 4.1 certification means it meets the Specialty Equipment Market Association's stringent standards for transmission containment and thermal management—compliance many sanctioning bodies require for competition vehicles. The integrated flexplate design ensures fitment-specific precision for TH400 applications, eliminating clearance guesswork. At 5 pounds, the assembly adds minimal rotating mass while delivering measurable heat rejection away from the transmission case, cooler fluid temperatures, and extended transmission life under sustained load.
This shield is purpose-built for builders and enthusiasts who have invested in a quality TH400 rebuild or upgrade. Whether you're running a street car with serious horsepower, a weekend drag strip competitor, or a off-road truck with a modern drivetrain swap, thermal management and containment protection are non-negotiable. The TH400 Ultrashield bridges that gap between transmission durability and competition-grade protection without requiring exotic materials or fabrication work.
TH400 transmission shields are not one-size-fits-all. CSR Performance's flexplate-specific engineering ensures correct geometry, mounting interfaces, and heat-shedding performance for your exact application. This kit ships complete and ready to install, sparing you fabrication headaches and ensuring you meet any SFI compliance requirements your build demands.
