The GM Throttle Bodies category from Granatelli Motor Sports showcases a full lineup of high‑performance drive‑by‑wire throttle bodies engineered to increase airflow, sharpen throttle response, and unlock additional horsepower for popular GM engines. Designed for platforms such as the LS3 6.2L, LT1, LT4, and LT5, these upgraded throttle bodies replace restrictive factory units with precision‑machined billet components that allow your engine to breathe more efficiently. Featured products like the Granatelli LS3 6.2L Billet Throttle Body (GMTBLS3P), the aggressive 108MM LS3 unit (GMTBLS108), and the robust LT1/LT4/LT5 112MM Billet Throttle Body (GMTBLT112B) are built to improve airflow volume and velocity, which is ideal for modified street builds, forced‑induction setups, and high‑RPM performance applications. Whether you’re upgrading a Camaro SS, Corvette, CTS‑V, or any LS/LT‑based swap project, these throttle bodies provide a significant performance advantage by helping improve throttle accuracy, enhance drivability, and support higher horsepower potential across a wide range of GM engines.
