Holley Alternator Relocation Kit

2009–Present Dodge Gen III Hemi Engines (5.7L & 6.4L)

97-369

Overview:

The Holley Gen III Hemi Alternator Relocation Kit with Holley Alternator is engineered to solve one of the most common challenges faced during Gen III Hemi engine swaps: alternator clearance on the passenger side of the engine. Many factory "car style" accessory drive systems position the alternator low, causing interference with the vehicle frame in popular swap applications such as 1972–1993 Dodge D100/D150 trucks and 1997–2004 Dodge Dakota models.

This kit relocates the alternator inward and lower using a robust steel bracket, providing the necessary clearance for smooth installation and reliable operation. It includes a compact Holley alternator that is smaller and shorter than typical alternators, simplifying wiring and compatibility with a wide range of engine control systems. Designed specifically for Gen III Hemi engines equipped with Variable Valve Timing (VVT) and factory "car style" accessory drives, this kit is a must-have for enthusiasts performing Gen III Hemi swaps into classic trucks and other vehicles with tight engine bay constraints.

Key Features:

Designed to enhance fitment and functionality, the Holley Gen III Hemi Alternator Relocation Kit offers the following key features:

• Relocates the alternator low and inward to provide extra clearance on the passenger side frame during Gen III Hemi engine swaps
• Includes a compact Holley 150 amp alternator (model 197-302) that is smaller and shorter than factory units
• Black powder-coated steel bracket for superior corrosion resistance and long-lasting durability
• Easy two-wire plus ground wiring design simplifies installation and eliminates the need for factory Mopar ECU excitation
• Compatible with any engine management system, including Holley Terminator X, Dominator, and HP EFI platforms
• Steel construction provides strength and resistance to flex under engine vibration and load
• Fits Gen III Hemi engines with VVT and “car style” accessory drive systems from 2009 and newer 5.7L and 2011 and newer 6.4L engines
• Provides critical clearance for popular swap vehicles such as 1972–1993 Dodge D100/D150 and 1997–2004 Dodge Dakota trucks
• Includes all necessary mounting hardware and pulley for a complete installation

Construction & Design:

The relocation bracket is crafted from high-strength steel and finished with a durable black powder coat to resist corrosion and maintain a clean appearance over time. The design focuses on rigidity to prevent bracket flex and maintain proper alternator alignment under all operating conditions. The included Holley alternator features a natural aluminum finish and a compact footprint, making it ideal for tight engine bays where space is limited. Its internal design supports a robust 150 amp output to meet the electrical demands of modern Gen III Hemi engines and aftermarket EFI systems.

Installation & Fitment:

This kit is engineered for straightforward installation on Gen III Hemi engines equipped with factory “car style” accessory drive systems and VVT, specifically 2009 and newer 5.7L and 2011 and newer 6.4L engines. It is especially beneficial for engine swaps into vehicles with limited passenger side frame clearance, such as 1972–1993 Dodge D100/D150 and 1997–2004 Dodge Dakota trucks. Installation requires removal of the factory alternator and bracket, followed by mounting the Holley bracket and alternator in the relocated position. The simplified wiring harness uses only two wires plus ground, eliminating the need for factory ECU excitation signals and making it compatible with a wide range of aftermarket engine management systems.

What's Included:

• Black powder-coated steel alternator relocation bracket
• Holley 150 amp alternator (model 197-302) with natural aluminum finish
• Mounting pulley
• All necessary hardware for installation

Ideal For:

This alternator relocation kit is ideal for automotive enthusiasts and professional builders performing Gen III Hemi engine swaps into classic Dodge trucks and other vehicles where factory alternator clearance is an issue. It is perfect for those running aftermarket EFI systems such as Holley Terminator X, Dominator, or HP EFI, as it eliminates the need for factory ECU alternator excitation wiring. Whether restoring a classic Dodge D100/D150 or upgrading a Dodge Dakota with a modern Gen III Hemi, this kit provides a reliable, clean, and professional solution to alternator clearance challenges.
