Accessory Sys. Drive Kit GM LS Engines

The Accessory Sys. Drive Kit GM LS Engines from Holley is essential for any serious LS engine build where accessory management is crucial. This kit is ideal for upgrading street machines, restomods, or high-output performance platforms, providing a complete serpentine drive solution specifically engineered for the compact LS platform.

Holley's system simplifies the process of sourcing individual pulleys, brackets, and belts by packaging everything needed to manage the alternator, water pump, power steering, and air conditioning in one coordinated assembly. The drive kit features precision-machined aluminum and ductile iron components designed to withstand sustained high-RPM operation while maintaining belt tension and reducing harmonic vibration.

Builders working with Gen III, Gen IV, or LS9 variants will appreciate this kit's broad compatibility across the LS family, whether performing an engine swap, crate motor installation, or complete drivetrain retrofit. The installation pairs seamlessly with both stock and custom engine mounts, and the compact footprint is designed to fit in tight engine bays.
