Description

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.
