FAST Throttle Body

2003–2018 Dodge, Chrysler, Ram 5.7L Hemi

Part #: 54088

Overview

The FAST 87MM Throttle Body is a precision-engineered performance upgrade designed specifically for Dodge, Chrysler, and Ram vehicles equipped with the 5.7L Hemi engine from 2003 through 2018. This throttle body enhances throttle response and overall engine efficiency by addressing common issues found in stock and aftermarket units, such as throttle blade deflection. Ideal for enthusiasts seeking improved drivability and throttle control, it is especially beneficial for boosted or modified applications where throttle precision is critical.

By increasing the throttle blade thickness and incorporating a smoother offset blade pivot, the FAST throttle body delivers a more consistent and responsive throttle feel. Its robust construction and dual throttle spring mechanism ensure reliable operation under demanding conditions, making it a trusted choice for performance upgrades.

Key Features

Engineered for durability and performance, the FAST 87MM Throttle Body offers the following key features:

• Increased throttle blade thickness to eliminate deflection and improve durability
• Smoother operating offset blade pivot for enhanced throttle response
• Beefed-up linkage and dual throttle spring mechanism for total throttle control
• 87mm throttle bore optimized for 5.7L Hemi engines
• Constructed from high-quality billet aluminum for strength and lightweight performance
• Black wrinkle powder coating for corrosion resistance and a sleek appearance
• Direct bolt-on fitment for a wide range of Dodge, Chrysler, Ram, and Jeep 5.7L Hemi models
• Improved airflow characteristics compared to stock throttle bodies

Construction & Design

The FAST 87MM Throttle Body is crafted from billet aluminum, ensuring a strong yet lightweight component that withstands the rigors of high-performance use. The design incorporates a thicker throttle blade to prevent the common issue of blade deflection, which can negatively impact throttle precision and reliability. The offset blade pivot mechanism is engineered for smooth operation, reducing friction and improving throttle response.

Finished with a durable black wrinkle powder coat, this throttle body resists corrosion and maintains its appearance even under harsh engine bay conditions. The reinforced linkage and dual spring setup provide consistent throttle control, essential for both street and performance driving scenarios.

Installation & Fitment

This throttle body is designed for direct replacement of the factory unit on compatible vehicles, requiring no major modifications. It fits a broad range of Dodge, Chrysler, Ram, and Jeep models equipped with the 5.7L Hemi engine produced between 2003 and 2018. Installation typically involves unbolting the stock throttle body and replacing it with the FAST unit, followed by standard throttle body relearn procedures as recommended by the vehicle manufacturer.
