The PHR 4 Piece Billet Aluminum Pulley Set is designed to enhance the performance of your Lexus IS300 and 1997-2004 GS300 by reducing rotating mass. This kit is precision machined from solid 6061-T6 aluminum, offering a lightweight yet durable solution. The set includes four essential pulleys: Power Steering Pulley, Water Pump Pulley, Alternator Pulley, and an Idler Pulley. These pulleys are direct replacements for the factory components, requiring no new hardware or spacers. They maintain the same diameter as the original parts, so no belt change is necessary. Available finishes include Machined, Black edition, and Polished, allowing you to match your engine bay aesthetics.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
