Construction & Design:

Holley’s mid-mount accessory system is crafted from durable cast aluminum components finished in sleek black for a modern yet classic look. The bracketless design reduces complexity and weight by integrating the accessory mounts directly into the timing cover casting. This approach not only improves engine bay aesthetics but also enhances reliability by minimizing the number of brackets and fasteners.

The system’s water pump utilizes a cartridge-style design, allowing for straightforward maintenance without disassembling the entire front cover. The power steering pump features a baffled reservoir to prevent fluid aeration and ensure consistent pressure, especially important for older steering box applications. The compact SD7 A/C compressor and premium alternator are engineered for tight packaging and long-lasting performance.

Installation & Fitment:

Designed with ease of installation in mind, this accessory system fits a broad range of Dodge and Jeep vehicles equipped with Gen III Hemi engines from 1966 to 2006, including the Dodge Challenger (1970–1974), Charger (1966–1978), Dakota (1987–2004), Magnum (1978), Ramcharger (1974–1993), and Jeep Wrangler (1987–2006). The kit requires no adapters or spacers, and color graphical instructions guide you through each step for a straightforward assembly process.

The compact layout eliminates common clearance issues found with factory accessory drives, such as interference with frame rails or hood clearance, making it suitable for both restoration projects and performance builds. Wiring the alternator is simplified as it does not require the factory ECU to excite it, further reducing installation complexity.
