Granatelli Motor Sports GMTBLT112 Billet Throttle Body GM Drive-By-Wire - 112mm LT1/LT4/LT5

The Granatelli Motor Sports GMTBLT112 is a high-performance 112mm billet throttle body engineered specifically for GM's LT-series engines including LT1, LT4, and LT5 platforms. This precision-machined throttle body features a drive-by-wire (DBW) electronic design that maintains factory functionality while significantly increasing airflow capacity over stock components.

Key Features:

• 112mm bore diameter provides maximum airflow for high-performance applications
• CNC-machined from solid billet aluminum for superior strength and durability
• Natural aluminum finish for clean, professional appearance
• Drive-by-wire compatible—retains factory electronic throttle control
• Direct bolt-on replacement for GM LT1, LT4, and LT5 engines
• Precision-machined blade shaft and bore for optimal airflow characteristics

This throttle body is ideal for performance builds, forced induction applications, and engine swaps where increased airflow is critical. The larger 112mm opening reduces restriction and supports higher horsepower and torque output compared to factory throttle bodies. Compatible with 2014+ GM Gen V LT-series small block engines found in Corvette, Camaro, Silverado, and other GM performance vehicles.
