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.

JET underdrive pulley sets reclaim lost horsepower and mileage by reducing the drag placed on the engine to drive the accessories, such as the air conditioning, power steering, and water pump. The pulleys slow down these accessories to allow the engine to turn with less effort without any adverse effect on the operation of A/C, power steering, charging, or cooling systems. Installation consists of simple bolt-on replacement of the stock pulleys. Kits include pulleys, hardware, complete instructions, and part number for new serpentine belt as most kits will require use of smaller size belt. Belt is not included with kit. The number and type of pulleys will vary per application.
