Product Description
Has your Infiniti Q60 or Q50 had the drive belt shredded, flown off, or just squealing for no reason? The Infiniti Q60's / Q50's have a notorious issue with shredding drive belts due to a misaligned A/C Compressor. Nissan / Infiniti updated the smooth idler pulley whenever Nissan released the new Z equipped with the VR30. The new smooth (lower) idler pulley comes with lips on the front and rear of the pulley to ensure the belt will not uninstall itself. These tall lips keep the belt aligned, while the old design allowed the belt more wiggle room and caused a lot of belts to shred while driving.
If your Q60 / Q50 has a pre-03/2022 production date then you have the old style pulley, and we highly recommend upgrading.
This upgraded pulley comes with a new belt to ensure you do not re-install a damaged belt.
Fits:
- 2016-2021 Infiniti Q50 (VR30DDTT)
- 2017-2021 Infiniti Q60 (VR30DDTT)
The replacement idler pulley will replace the pulley highlighted in red below.

Order this kit because the stock part on the car is made of plastic. This kit was a huge help.

Super happy with it and the install was medium difficulty due to the space. Very simple to do though. Looking to save a couple bucks? If possible you can have the car sit, remove the belt check for any damage and if there is none just buy the pulley. In my case my belt was actually fine due to the squeak happening temporarily rather than a long time which will cause damage and cracking. So it mainly a pulley issue but if you feel it’s better to be safe than sorry then by all means get both! Pulley is definitely needed comparing the lips on the side that keep the belt for shifting side to side and build quality is great giving that it’s metal compared to the plastic OEM one with no lips. If you’re looking to buy the belt as well you could go for OEM or Z1, no preference besides price but the Z1 belt feels great and just a bit thicker than OEM but maybe that’s to the time my old one had been in use compared to brand new. You should also screenshot the diagram of the belt to know how to put it back, there’s one listing on Z1 with a low quality detail and another with great and clear detail so make sure you screenshot the right one!

I purchased the anti slip pulley for my 2021 RS400 and it arrived quickly even though the part was back ordered. The anti slip pulley was installed with perfect figment and is working as intended. The new pulley is clearly a high quality upgrade worth every penny when compared to the hard plastic 2021 OEM version. Thank you Z1!
