Product Details

The FAST Big Mouth throttle body features an 87mm bore, offering a significant airflow increase over stock for your Chrysler Hemi. This updated version is constructed from billet aluminum and includes an improved throttle blade and pivot system. The thicker throttle blade is designed to eliminate deflection, which is a common issue, especially in boosted applications. This means more consistent and reliable throttle control when you need it most.

Beyond the beefed-up blade, you'll find a smoother operating offset blade pivot that contributes to improved throttle response. The linkage has been strengthened, and a dual throttle spring mechanism ensures positive and complete throttle control. This well-built unit is finished with a black-wrinkle powder coating, giving it a solid look under the hood. It fits a wide range of Chrysler and Dodge vehicles, including the 300, Charger, Challenger, and Ram trucks, as well as Jeep Grand Cherokees.

When upgrading your engine's breathing, this throttle body is a key component. While it's a direct fit for many Hemi applications, always refer to the manufacturer's installation instructions for any specific details or hardware requirements. This part is not CARB approved and cannot be shipped to California.
