blox upper adjustable camber arms, camshaft, and turbo manifold. my only complaint is when i was installing my cam, the notch thats on the end of the stock cam for the gear to slide on to is kind of a rectangular shape. the notch on the blox cam was a cresent shape, so i had to grind it down to get the gear on. it seems to me that they would have thought that one through.... but everything beside that has been good. no complaints
