Holley Billet Aluminum Power Steering Pump Pulley

2014 and Up Mopar Gen III Hemi 5.7L / 6.4L Muscle Cars & Trucks

97-383

Overview:

The Holley Billet Aluminum Power Steering Pump Pulley is engineered specifically for late-model Mopar Gen III Hemi engines, including the 5.7L and 6.4L variants from 2014 onward. Designed to address the excessive power steering pressure produced by the factory pump, this pulley ensures compatibility with older muscle cars and trucks that utilize low-pressure steering boxes. By working in conjunction with the Saginaw type II power steering pump (part #198-104), it reduces pressure to safe levels, preventing damage to vintage steering components while maintaining proper pump speed and performance.

This pulley is an essential upgrade for enthusiasts performing Gen III Hemi engine swaps into classic muscle cars and trucks, offering a reliable and durable solution that integrates seamlessly with existing accessory drive systems.

Key Features:

Holley’s billet aluminum pulley delivers precise control over power steering pump speed and pressure, ensuring optimal steering feel and component longevity. Key features include:

• Compatible with Saginaw type II power steering pump (198-104) to reduce excessive pressure on older steering boxes
• Prevents premature wear and damage to factory low-pressure steering boxes commonly found in muscle cars and trucks
• Designed to bolt directly to existing tapped holes on the left side cylinder head of Gen III Hemi engines
• 6-rib billet aluminum pulley with a durable black anodized finish for corrosion resistance and long-lasting appearance
• Precisely sized to operate the power steering pump at the correct speed within Gen III Hemi accessory drive systems
• Compatible with both “car style” and “truck style” accessory drive configurations on 2014 and newer Gen III Hemi engines
• Complete kit option (part #97-382) available including pump, reservoir, mounting bracket, hardline adapter, and pulley
• Ideal for engine swaps, restoring proper steering function and reliability in classic muscle cars and trucks

Construction & Design:

Crafted from high-quality billet aluminum, this pulley combines strength and lightweight properties to withstand the rigors of performance driving. The black anodized finish not only enhances corrosion resistance but also provides a sleek, professional appearance under the hood. Precision CNC machining ensures exact fitment and balanced operation, reducing vibration and wear on the power steering pump and accessory drive belt.

The 6-rib design matches factory belt profiles for reliable grip and smooth power transfer, maintaining consistent pump speed and pressure control essential for safe steering performance.

Installation & Fitment:

The Holley billet pulley bolts directly to the left side cylinder head of 2014 and newer Mopar Gen III Hemi 5.7L and 6.4L engines using existing tapped holes, requiring no modifications to the engine block. It is designed to work seamlessly with the Saginaw type II power steering pump (198-104) and can be paired with Holley billet aluminum mounts (97-379 or 97-380) for a complete installation.

This pulley fits both car-style and truck-style accessory drive systems, making it an ideal choice for engine swaps into classic muscle cars and trucks where the original steering box requires reduced pressure for longevity and proper function.

What's Included:

• Billet aluminum power steering pump pulley with black anodized finish (part #97-383)
• Note: Complete power steering pump kits including reservoir, mounting bracket, and hardline adapter are available separately (part #97-382)

Ideal For:

This pulley is perfect for automotive enthusiasts and restorers upgrading or swapping Gen III Hemi 5.7L or 6.4L engines into older muscle cars and trucks. It ensures safe, reliable steering performance by reducing excessive pressure that can damage vintage steering boxes. Whether restoring a classic Mopar or building a modern muscle car with a Gen III Hemi, this pulley provides a critical component for a successful power steering system upgrade.
