Q60 / Q50 VR30 Anti-Jump Belt Upgrade Kit

Huge difference from the factory pulley. This thing is hefty. Much needed upgrade and stopped that embarrassing squeeeeeeel. Belt is very sturdy compared to the OE belt. Idles smoother/quieter as well

No issues other than it squealing like a murdered pig. So damn annoying.

Easy to install. Remove the fear of the jumping belt, usual in VR30s pre 2022

Awesome products. I wish the belt would last longer.

100% recommended this part is needed

Great part fast shipping

Perfect upgrade. No more Chirp and I don’t think it’ll ever come back unless I fail to replace the belt. I keep the Z1 belt in my trunk for shiggles. Just incase.

Easy and proactive mod, one of the 1st rings I did and it gives me a piece of mind overall.

I bought two of them but one was defective and make a loud squeaky sound.

The pulley itself is great but unfortunately the z1 belt isn't the best at all, had installed the belt and 3-4 days later had extremely loud squeaking coming from belt, i bought the oem belt and the issue was solved unfortunately i do not recommend buying the Z1 belt spend the extra 30$ for the oem one and save yourself the headache

Should have bought the whole kit-kit. But my 2021 luxe RWD (got red sport power say what you will lol) didn't come with a 400z pulley with a lip. So when it was time, I installed these. Runs better.

Looking up the pulley by it self it is cast effective to buy as a kit.and to get rid of the thin plastic pulley. But I do use a Gates belt.

Certainly would recommend this to anyway wit more than 400 horsepower

High quality belt worth every penny

The pulley came damaged and dented

Quality belt, obviously quality oem pulley, quick shipping 5 stars!

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

Took care of my belt squeak and was easy to install.

Super easy install took care of the belt squeal I had!!

A definite must for q50 owners and buy an extra belt to have in hand doesn’t hurt

Es una parte muy buena exactamente lo que necesitaba

Love the anti jump belt upgrade. No more worrying about my belt being ripped apart while driving!

Pretty smooth install. No squeeks or issues.

Better than oem and the updated pulley with the lip helps a lot!

Waited to leave a review on this. 15,000 miles on the z1 belt with no issues

Love this upgrade. Now I don’t have to worry about the belt getting shredded.

perfect fit! No issues

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!

Great product ! fixed my belt noise.

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!

Great upgrade! Thanks Z1MOTORSPORTS. My go to website when I need Oem parts for less.
