Construction & Design

Every BBK throttle body is precision CNC machined from a new, high-quality 356 aluminum casting, ensuring excellent strength-to-weight ratio and corrosion resistance. The manufacturing process guarantees tight tolerances for optimal airflow and throttle plate sealing. The assembly includes OEM-style die-stamped throttle linkages that replicate factory cable drive mechanisms for smooth, reliable operation.

To enhance durability and performance, BBK incorporates double sealed bearings and O-ringed throttle shafts, which minimize air leaks and maintain consistent throttle response over time. This attention to detail results in a throttle body that not only improves airflow but also maintains the reliability and drivability expected from a factory component.

Performance & Sound

By increasing airflow by up to 30%, the BBK 85mm throttle body enhances engine breathing, which translates into noticeable gains in horsepower and torque. The improved throttle response delivers a more immediate and precise feel when accelerating, making your Gen 3 HEMI-powered vehicle more responsive and engaging to drive. While primarily focused on performance, this throttle body maintains smooth and predictable operation without negatively affecting engine sound or drivability.

Installation & Fitment

This throttle body is designed as a direct-fit replacement for Gen 3 HEMI 5.7L, 6.1L, and 6.4L engines that use a cable-operated throttle system. It is ideal for crate engines and retro engine swaps requiring a cable drive throttle body. Installation is straightforward and requires no modifications to the factory throttle cable or linkage. The unit supports factory Mopar throttle position sensors and idle air control valves, allowing it to integrate seamlessly with the vehicle’s original wiring and engine management system.
