the nismo/pro4x have larger stock tires, better shocks, skid plates, and a diff lock. If you are going to get all new suspension stuff, it may be better to get a different model unless, the skids and locker are worth it. The locker only work in 4lo unless you modify it, and it sound like your not a rock crawler type. There are alot of lift options. PRG products sells a range of stuff. There is a ton to read about. Read the stickies, they have alot of good info in them.
