My improperly torqued pulley nut released itself on the highway. In order to get the nut and the shim I had to purchase a new idler pulley assembly. I paid $91 for a nut and a shim!!!! This pulley is a brand new OEM piece however you will need to reuse your front nut and shim (which is standard practice). My price includes shipping. I'd be happy to include an OEM belt for an additional $20. This pulley fits the following vehicles

INFINITI FX35 (2003 - 2008)
INFINITI FX45 (2005 - 2008)
INFINITI G35 (2003 - 2007)
INFINITI M35 (2006 - 2008)
INFINITI M45 (2007 - 2010)
INFINITI Q45 2002
INFINITI QX4 (2002 - 2003)
NISSAN 350Z (2003 - 2006)
NISSAN PATHFINDER (2001 - 2004)

In summary
Pulley: $50 Shipped
Pulley + Belt: $70 Shipped
