Accessory Drive Bracket Spacer Kits, Aluminum, Natural Finish, Short Alignment, Chevy, Small Block LS, Each
Holley LS engine accessory drive kits offer simple, clean, cost-effective solutions when swapping a GM LS engine into a muscle car, truck, hot rod, or any other vehicle. These bracket kits deliver a factory-style appearance, correct belt alignment, and factory stability. They fit virtually all common LS engines, regardless of water pump and harmonic balancer offsets—reducing cost and complexity. Holley LS engine accessory drive kits position the A/C compressor high above the crossmember, but below the hood line, for an easy installation. The brackets are manufactured from diecast aluminum with a natural, polished, or black finish. (An application-specific installation kit is required, but sold separately.)
