I Just finished installing new suspension in My '01 Pathfinder, up front I put in KYB Excel G-Gas Struts with Adelco Springs (Stock size) and a 1.5" SFCreations spacers (gives about a 2 inch lift), in the rear I put NRC9449 coils which are a HD Coil with KYB Gas-A-Just Gas Shocks (Have around a 2.5" plus lift in the back). I'll admit with the 9449 coils the back rides a lot stiffer especially over speed bumps. All in everything cost around $800 CAD with shipping. I used Rockauto, LRDirect, SFCreations.
I did all the work myself, Struts were the hardest which took a few days and rear finished in a couple hours. The 9447 I believe gives close to a 2" lift in the rear.
