Note on Vehicle Configuration
This listing includes the term "driver" or "passenger". Please note that this may refer to a region specific variation based on vehicle configuration (LHD/RHD) or regional preferences. Much of our database relates to US sourced products where "Driver" typically refers to the left-hand side in LHD vehicles, and "passenger" to the right. In RHD vehicles, this terminology is reversed. Review product details carefully for compatibility. Contact support if you have any questions. StreetFX may not accept returns for special order products.
(keyword: passenger)Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase. For assistance or clarification, please contact customer support.

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.
