OME 2.5" Available here:

There is a new disclaimer, reads as follows:
North America Pathfinder Owners 2005+, please be advised: On US and Canada Nissans, this kit provides around 2.5" of lift which has been known to cause alignment problems leading to a potentially poor handling vehicle. No warranty on any late pathfinder suspension components and no returns.
I believe that if you have an 05 you have camber bolts that allow you to adjust the alignment within spec.
From prg's website
If you have any Nissan truck built after 2006, it did not come with adjustable lower a-arm pivot bolts. These bolts are often needed to properly align the truck. These come in sets of 4 bolts, 8 washers, and 4 nyloc nuts.
