    Big Mouth LT Throttle Bodies

    Specifications:

    Manufacturer's Part Number:
    54091

    FAST's Big Mouth Throttle Bodies for the LSX 92mm and LSXR/LSXRT 102mm Intake Manifolds increase airflow through a series of innovative design changes and an enlarged throttle opening. These throttle bodies offer increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those in boosted applications. A smoother operating offset blade pivot improves throttle response, and a beefed up linkage and dual throttle spring mechanism ensure total throttle control. Constructed from billet aluminum, the FAST Big Mouth 92mm Throttle Body will deliver bolt-on GM Gen III (LS1/2/6) horsepower, while the 102mm version is designed to maximize performance upgrades on all Gen III and Gen IV engines with cable driven throttle bodies.

    Also available for LS, Ford Coyote and Chrysler Hemi applications are the Big Mouth LT Throttle Bodies, new and improved versions of the original Big Mouth Throttle Body. With a 92mm throttle bore for LS and 87mm for the Ford Coyote and Chrysler Hemi, each one features black-wrinkle powder coating and all of the same features as the original.

    Features:

    • Designed to work with FAST LSX 92mm & LSXR 102mm Intake Manifolds
    • Better airflow than OEM or aftermarket 90mm units due to enlarged throttle opening and modified internal design
    • Dual spring mechanism and beefed up linkage for total throttle control
    • Increased thickness of both the throttle blade and the shaft resists deflection, especially in boosted applications
    • Offset blade pivot allows for smoother operations & significantly improves throttle response
    • Big Mouth LT Throttle Bodies available for LS, Ford Coyote and Chrysler Hemi applications
