GM 85mm Throttle Body - LS1 w/Cable Style Thrtl.

The BBK Performance GM 85mm Throttle Body with cable-style actuation is designed specifically for LS1-powered platforms, providing precise fuel delivery and responsive throttle control in high-demand applications. This throttle body is engineered for GM F-Body vehicles from 1998 to 2002 and is also compatible with LS-series engine swaps, making it an excellent choice for performance upgrades.

Constructed from durable aluminum and finished in natural mill, the 85mm single-blade design optimizes volumetric efficiency while avoiding resonance or flow restrictions that smaller units may introduce. The three-bolt mounting flange integrates seamlessly with GM LS-series intake manifolds, and the cable-style throttle linkage allows for direct mechanical control, simplifying older fuel-injection conversions or transitions from carbureted systems.

Ideal for engine builders, restoration shops, and performance enthusiasts, the BBK Performance 85mm throttle body enhances installation ease on 1998–2002 GM F-Body platforms while ensuring consistent performance across the RPM band. This component is perfect for those upgrading a Camaro, Firebird, or Trans Am, or integrating an LS powerplant into a chassis swap.
