Those are the same blue and yellow Toyota billies that I got from a Tundra for my lift. The front end setup is correct. The top plate spacers are added to give more than 2" of lift since the struts aren't adjustable...its the same front setup Fightman has. The rear shocks, I wouldn't know, I went with OME. To agree with hungryeddy, the guy doesn't mention SS kits at all, just that this stuff is used for as a lift.
However, this guy is asking way too much for this setup, especially since one would still need to buy rear springs. I paid $350 for everything for mine, and didn't have worn out bushings. I wouldn't give that guy $200, let alone $300.
