Underdrive Crankshaft Pulley

The Jet Performance 90118 is an underdrive crankshaft pulley engineered to enhance engine performance by reducing accessory drag. This component reclaims lost horsepower and mileage by decreasing the load from accessories such as the air conditioning, power steering, and water pump. By slowing down these accessories, the Jet Underdrive Pulley allows the engine to operate with less effort, ensuring that the A/C, power steering, charging, and cooling systems continue to function optimally. Installation is straightforward, involving a simple bolt-on replacement of the stock pulleys. The kit typically includes pulleys, necessary hardware, and complete instructions. It's important to note that while the kit provides a part number for a new serpentine belt, a belt is not included, and most applications will require a smaller size belt. This underdrive crankshaft pulley is specifically designed for the 1996-2001 Chevrolet Cavalier models equipped with the 2.4L 4-Cyl. engine. It is designed to deliver an increase of 10-30 horsepower, improve fuel economy, and enhance acceleration, offering a noticeable improvement in overall driving experience.
