  • Description

    When your LS build is moving serious air, the throttle body should not be the restriction. The Granatelli 112mm billet Drive-By-Wire throttle body is built for high-horsepower LS and LSX combinations that demand massive airflow, strong electronic throttle control and dependable performance under boost.

    The Granatelli GMTBLS112B 112mm Drive-By-Wire Throttle Body features a massive 112mm bore and precision CNC-machined 6061-T6 billet aluminum construction. Finished in black anodizing, it delivers the airflow capacity and durability required for aggressive naturally aspirated and forced-induction GM LS applications.

    A reinforced throttle blade assembly and powerful electronic motor are engineered to remain stable under high airflow and boost pressure, making the GMTBLS112B an excellent choice for large-displacement LS engines, supercharged combinations, turbo builds and other applications where a factory-size throttle body can become a restriction.

    112MM OF SERIOUS LS AIRFLOW.

    ENGINEERED FOR 25+ PSI BOOST

    Built for combinations where airflow demand goes far beyond stock, the Granatelli 112mm DBW throttle body combines a massive bore with a reinforced motor and blade assembly designed for extreme-performance LS applications.

    Key Features

    • Massive 112mm throttle bore for increased airflow capacity
    • Designed for high-performance GM LS & LSX applications
    • Drive-By-Wire electronic throttle control
    • Uses a late-model GM 6-pin DBW connector
    • Precision CNC-machined from 6061-T6 billet aluminum
    • Black anodized finish for durability and a premium appearance
    • Reinforced motor and throttle-blade assembly
    • Engineered to support 25+ psi boost
    • High-torque electronic motor helps prevent throttle-blade slamming or unwanted closure under boost
    • Excellent for naturally aspirated and forced-induction combinations
    • Ideal for TVS, Whipple, Roots-style supercharger and turbo applications
    • Can be used with compatible factory or aftermarket intake manifolds
    • No need to transfer electronics from the original throttle body
    • Designed to improve airflow volume and throttle response
    • Made in the USA

    Performance Application: The GMTBLS112B is designed for serious performance combinations where increased airflow is required. A tune may be required to optimize throttle operation and engine performance, especially on modified or forced-induction applications.

    Massive 112mm Airflow Capacity

    A high-output LS engine can only make power if it can breathe. The 112mm throttle opening dramatically increases available inlet area compared with smaller factory-style throttle bodies, helping reduce airflow restriction at higher RPM and on engines with substantial airflow demand.

    Built for High-Boost Applications

    Forced-induction systems place additional load on an electronic throttle blade and motor. Granatelli equips the GMTBLS112B with a reinforced blade assembly and high-torque electronic motor engineered to handle upwards of 25 psi of boost while resisting unwanted throttle closure or blade movement under load.

    Precision 6061-T6 Billet Construction

    Each throttle body is precision machined from 6061-T6 billet aluminum for strength, dimensional accuracy and durability. The black anodized finish adds corrosion resistance while giving the throttle body a clean, aggressive appearance that complements high-end engine builds.

    Complete Drive-By-Wire Assembly

    Unlike throttle bodies that require transferring electronics from the factory unit, the Granatelli 112mm DBW throttle body is supplied as a complete electronic assembly. It uses a late-model GM 6-pin connector for compatible applications, simplifying installation on properly matched LS and LSX combinations.

    Compatible GM LS & LSX Applications

    Designed for high-performance GM LS and LSX engines using a compatible 6-pin Drive-By-Wire throttle-control system. Common applications include:

    LS2LS3LS7LS9LSAL76L92L99LSX

    Popular Performance Applications

    Application Notes
    LS3 / L99 Excellent for high-airflow naturally aspirated and boosted combinations
    LSA Excellent for TVS, Roots-style and other supercharged applications
    LS9 Suitable for compatible high-output supercharged builds with the correct intake setup
    LSX Ideal for large-displacement and high-horsepower crate or custom engine combinations
    Turbo LS Reinforced electronic throttle assembly designed for high-boost airflow demands

    Important Fitment Notice: This throttle body is designed for compatible GM LS and LSX applications using a late-model GM 6-pin Drive-By-Wire connector. Verify your intake-manifold bolt pattern, throttle opening, electrical connector and available clearance before ordering. Some intake manifolds may require an adapter.

    Tuning Notice: A tune may be required for proper operation and optimum performance, particularly on highly modified, forced-induction or custom engine combinations.

    Trailblazer SS: Granatelli recommends calling before ordering for Trailblazer SS applications to confirm calibration compatibility.
