If you have already found out the hard way, Chrysler/VM have discontinued the fan pulley and bracket assembly. So when your pulley bearings go bad, junkyard hunting used to be your only option. Not anymore! This kit lets you rebuild the oem bracket with a new bearing cartridge and pulley assembly to keep your jeep on the road! The bearing cartridge uses 4 off the shelf sealed metric bearings that are easily replaced if they ever wear out in the future.
