What makes this throttle body better than stock for boosted engines?

This FAST throttle body features a thicker throttle blade designed to prevent deflection, which is a common issue with stock units under boost. The beefed-up linkage and dual spring mechanism also ensure more precise throttle control when you're pushing higher horsepower.

Does this throttle body come with everything needed for installation?

This throttle body includes the throttle body unit itself. It is designed as a direct replacement for your factory unit, but you may need to reuse some original hardware or sensors depending on your specific vehicle. Refer to the manufacturer's installation instructions for details.

What is the black-wrinkle powder coating for?

The black-wrinkle powder coating is a durable finish applied to the billet aluminum construction. It not only gives the throttle body a clean, aggressive look but also helps protect it from corrosion and wear over time.

Product Details

Starting with an 87mm throttle bore, this FAST Big Mouth throttle body is built from billet aluminum for a solid foundation. It's designed to handle the demands of your Hemi engine, especially if you're running boost. The throttle blade is thicker than stock to prevent deflection, which can happen on other throttle bodies under pressure. This means more consistent control when you're on the gas.

You'll notice improved throttle response thanks to a smoother operating offset blade pivot. Plus, a beefed-up linkage and a dual throttle spring mechanism work together to ensure you have total control over your throttle. This is an updated version of the original Big Mouth throttle body, featuring a durable black-wrinkle powder coating for a clean look that holds up. It's designed to fit a range of Chrysler Hemi vehicles, including models like the Dodge Charger, Jeep Grand Cherokee, and Ram 1500, among others.

When you're looking to get the most out of your Hemi, a well-built throttle body like this one makes a difference. It's a direct replacement for your factory unit, making installation straightforward. Just be aware that this part is not CARB approved and cannot be shipped to California.
