Complete Mid-Mount Acc. Drive Sys. GM Gen V LT

The Complete Mid-Mount Accessory Drive System for GM Gen V LT by Holley is a purpose-built serpentine pulley kit engineered for modern Chevrolet LT-series engine platforms. This black 6-rib kit replaces the factory accessory drive configuration with a streamlined mid-mount system, delivering cleaner engine bay aesthetics and improved component accessibility without compromising belt tension or alternator output.

The mid-mount design repositions ancillary components—including alternator, power steering pump, and air conditioning compressor—to a centralized location below the cylinder heads. This configuration reduces hose routing complexity, lowers parasitic drag on the serpentine belt system, and provides superior cooling airflow around critical engine surfaces. The 6-rib serpentine belt profile ensures compatibility with stock and upgraded alternators while maintaining OEM-level reliability margins. The black powder-coat finish resists corrosion and matches modern engine appearance standards.

Builders and enthusiasts running naturally aspirated or forced-induction Gen V LT platforms—including LS swaps into vintage chassis—select this system when factory accessory mounting conflicts with custom intake manifolds, supercharger installations, or tight engine bay applications. Installation requires basic mechanical competency and hand tools; compatibility with existing alternator capacity and serpentine belt length should be verified before purchase.

Holley's accessory drive systems are engineered within tight tolerance specifications to ensure proper belt alignment and idler pulley contact geometry. The mid-mount configuration represents a departure from OEM placement but has been validated across thousands of high-performance build applications, making it a proven alternative for builders prioritizing component positioning and thermal management.
