All American Billet FDS-LT4-301 Serpentine Kit GEN V LT4

The All American Billet LT4 Serpentine Kit with A/C and Power Steering is a complete front drive accessory system designed specifically for GM Performance LT4 6.2L supercharged wet-sump crate engines. Created to simplify engine swaps and modernize classic vehicles, the kit provides a clean, organized accessory drive solution for hot rods, street rods, and classic trucks while maintaining a professional, show-quality appearance.

The system includes all major accessories and mounting components required for installation, including a Sanden peanut-style air conditioning compressor, 180-amp alternator, GM Type II power steering pump, brackets, tensioners, stainless steel mounting hardware, and detailed instructions. The kit is engineered to work with the factory water pump and crank pulley/damper, reducing installation complexity and helping ensure compatibility.

A key feature of the kit is its customization options. Customers can choose between Classic Pulleys with a smooth, solid-face design or the company's original pulley style featuring triangular cutouts, both offered at no additional charge. The system is also available in multiple premium finishes, including Machined, Polished, Chrome, Silverline Series, and Black Anodized, allowing builders to match the look of their engine bay.

For customers requiring additional electrical output, All American Billet offers an optional 250-amp alternator upgrade, delivering up to 250 amps at 1,800 RPM and approximately 130-140 amps at idle speeds around 650 RPM. The kit is designed specifically for the 2016+ supercharged LT4 engines used in the Cadillac CTS-V and Camaro ZL1, GM Part Number 19355404, and is intended for wet-sump applications only.
