I just purchased a lightweight Crank Pulley for my 2007 Nissan Maxima from Z1 Motorsports.

When i called and talked to a Z1 employee last week, the guy told me that it is the same Pulley as the 350Z and that it should be a direct fit for my Maxima. I just ordered and decided to call again, a different employee can not say yes or no that it is the same. Does anyone know?? I would call Unorthodox Racing, but I can't find their number online.

 

Look to be out of stock?

Either way, I'd go with one from 2J.

What all is needed to install this? And are there any negatives from having it?

 

Luckily I called in and cancelled it before they shipped the order. I thank you for telling me about 2J. I actually never heard of them and am now buying their pulley instead. I hope this helps my car as much as I'm thinking it will. Thank you again for the tip, my paychecks do not thank you though. Lol
