Hey! I figured I'd add to this post in case you do want to add a lift to your Pathfinder, and because it sounds like exactly what I did last summer.
From what I read it seemed like a 2-inch lift was the absolute max for spacers on the Pathfinder. So, I went with a 2-inch spacer from Supreme Suspensions off of Amazon. The installation of the spacers did require the struts to be disassembled and I ended up pressing the top hat studs out using a c-clamp with a socket over one end of the stud. However, with the 2-inch lift, I came across a couple of issues.
First, I noticed that my CV boot had torn (not sure if this happened before or after lift installation) so I decided to replace them with ones from Autozone, which ended up binding due to the increased angle of the lift. Eventually, I bought TrakMotive Extended Travel CV axles from RockAuto which have worked great so far with no binding. Second, the camber on my front wheels was very positive after the lift, but I was able to nearly (+0.5 camber) correct with camber bolts, maybe getting a full alignment could solve the issue completely.
Overall, they definitely will require some work to install, but I was extremely happy with the outcome!
