FST Throttle Bodies

These throttle bodies offer increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those used in boosted applications. A smoother operating offset blade pivot improves throttle response, while a beefed up linkage and dual throttle spring mechanism ensure total throttle control. Constructed from billet aluminum, the FAST Big Mouth LT for Ford and Chrysler Hemi applications are new and improved versions of the original Big Mouth Throttle Body. With an throttle bore for the Ford and Chrysler HEMI, each one features a black-wrinkle powder coating and all of the same features as the original.
