Enhance chassis rigidity and driving confidence with the Speedlogix Rear Tunnel Brace, engineered for 2011–2023 Dodge Charger and Chrysler 300 models. This performance upgrade reinforces the rear tunnel area of the unibody, helping to reduce flex during acceleration, cornering, and aggressive driving for a more stable and controlled feel. Built from high-quality materials and precision-designed for a direct bolt-on installation, the rear tunnel brace adds strength without sacrificing ride quality or ground clearance. Ideal for both daily driving and performance-focused builds, it’s a smart upgrade for enthusiasts looking to improve handling, stability, and overall vehicle responsiveness while maintaining factory fitment.  Our chassis matrix tunnel brace is a direct replacement for the factory stamped steel unit and provides additional clearance for most larger diameter exhaust systems while still providing ample ground clearance.
