Powerhouse Racing is happy to offer our Billet Aluminum Lightweight Pulley Kit for the Lexus IS300 and 97-04 GS300. Precision machined from solid aluminum, this is the finest pulley kit available. Reduce rotating mass and keep accessory speed where it should be, not underdriven.
The PHR Billet Aluminum Pulleys are made of 6061-T6 Aluminum and the idler pulley features a precision bearing for lifelong performance and reliability. Although the bearing should NEVER fail, it is still serviceable.
It is a direct replacement for the factory pulleys, no new hardware of spacers necessary. It is the same diameter as factory and does not require a belt change.
