PHR PowerHouse Racing PHR Billet Aluminum Idler Pulley for 1JZ/2JZ

The factory idler pulley does its job… until you start caring about precision, longevity, and a cleaner engine bay. The PHR Billet Aluminum Idler Pulley is a CNC-machined upgrade built to match OEM belt routing and diameter while adding the fit/finish you expect from a real billet piece. Part of the PHR Lightweight Billet Aluminum Pulley Kit (Supra or SC) (GS or IS), tying the accessory drive together with a consistent look and quality.

Why this pulley

• CNC-machined 6061-T6 billet aluminum for a rigid, lightweight, high-quality upgrade.
• Precision bearing designed for long-term performance—and it’s serviceable.
• OEM diameter so belt length stays the same (no belt change required).

Fitment & installation notes

This pulley is designed as a direct functional replacement for the factory idler pulley, and it includes the required machined spacer/washer for the back side of the pulley to ensure proper alignment. Note, you'll reuse the factory bolt (unless you upgrade to the PHR Titanium Bolt) but ditch the factory washers (front side and back side). 

Finishes

Available in Machined Finish, Black edition, or Polished.
