Hayaku Automotive offers a premium replacement Smooth Idler Pulley for the Nissan 370Z & Infiniti G37, Q50, & Q60 3.7L at an affordable price. Each bearing is built to OE specifications for precise fitment and durability. This pulley comes with the mounting bolt for ease of installation, saving you money and installation time.
Over time, the bearings in your pulleys will wear, resulting in a squealing noise or a seized pulley. We recommend routine inspection of the drive belt system and replacement of any worn components.
There are THREE idler pulleys on the front of your VQ37VHR. This pulley, identified as the 'smooth' is shown in the parts diagram below.
The 2009-2013 option does not come with a mounting bolt, but the 2014+ option comes with the 8mm bolt that will not fit the earlier models.
Hayaku Pulleys have been tested to 1,000 hours and come with a 2-year / 50,000-mile warranty.

- 2009-2020 Nissan 370Z
- 2008-2013 Infiniti G37 Coupe
