FAST 54088 Big Mouth Billet Throttle Body Chrysler Hemi - 87mm

The FAST 54088 Big Mouth Throttle Body is a high-performance 87mm billet aluminum throttle body designed specifically for Chrysler HEMI engine applications. This premium throttle body represents an evolution of the original Big Mouth design, engineered to deliver superior airflow and throttle response for both naturally aspirated and forced induction builds.

Key Features:

• 87mm throttle bore diameter for maximum airflow capacity
• CNC-machined billet aluminum construction for strength and precision
• Increased throttle blade thickness eliminates deflection under boost pressure
• Smoother offset blade pivot design improves throttle response and linearity
• Reinforced linkage arm resists wear and fatigue
• Dual throttle spring mechanism ensures positive throttle control and fail-safe operation
• Durable black wrinkle powder coat finish resists corrosion and heat

The FAST Big Mouth throttle body addresses common weaknesses found in factory and aftermarket throttle bodies, particularly in turbocharged and supercharged applications where thin throttle blades can flex and cause inconsistent airflow. The beefed-up construction and dual return spring system provide confidence and reliability for high-horsepower street and track engines.
