96mm Throttle Body - GM LS2 Satin

The Professional Products 96mm Throttle Body for GM LS2 engines in satin aluminum finish is a precision fuel delivery component engineered for builders seeking consistent air-fuel mixture control across the entire RPM band. This single-blade design maintains stock flange compatibility while offering the flow characteristics required for naturally aspirated and modified LS-series powerplants. The satin aluminum construction provides corrosion resistance in high-heat engine bay environments while the 96mm bore diameter maximizes volumetric efficiency for engines in the 5.3L to 6.2L displacement range.

The 96mm bore size is a measured middle ground for LS-series applications—larger than stock units but smaller than full 102–105mm competition throttles. This diameter produces linear response characteristics essential for street and mild performance builds where throttle modulation matters as much as peak flow. The single-blade actuator design simplifies linkage setup compared to dual-blade variants, reducing binding risk during cold starts and idle conditions. At 5.06 pounds, the assembly carries minimal rotating and reciprocating mass, reducing parasitic losses on the engine's intake side. The aluminum body's natural finish resists scaling from repeated thermal cycling typical of high-horsepower applications.

This throttle body suits engine builders upgrading from restrictive factory units, LS swap installers requiring aftermarket intake solutions, and tuners preparing platforms for electronic fuel injection recalibration. The stock flange mounting pattern simplifies installation into existing manifolds without machining. Buyers integrating this component should verify fuel injection tuning compatibility and confirm that their engine management system supports throttle position sensor input for closed-loop idle control.

The 96mm throttle body occupies a practical segment within the LS platform ecosystem—not a race-only component, but a purposeful upgrade that supports both bolt-on performance packages and serious build platforms. Professional Products has positioned this design as a balance between airflow demand and real-world drivability. The satin finish protects the aluminum against oxidation, maintaining aesthetic consistency through multiple seasons of engine runs.
