Holley LS Series Accessory Drive Kits are simple, clean, cost-effective solutions to the accessory drive challenges encountered when swapping a GM LS engine into a muscle car, truck, hot rod, or other vehicle. Holley Kits supply the required brackets and hardware needed for installation yet allow you to choose the source for supplemental accessories and components that are often already on the engine or vehicle. These kits were designed to deliver correct belt alignment, factory stability, and stock-style appearance. Whether sourcing from the salvage yard, local auto parts store, GM parts dealer, or Holley, you pick the accessories that match your needs and budget!
