its the "x" series kit complete with front track bar, SS brake lines, heim joints on the control arms, shocks etc.... i think i might need to get the rear spring clips( to hold the springs in). i had 2.5 spring cups on it before with 33" 11.5"s on a 9" wheel and i rubbed when i got the jeep crossed up on the trail. i'm getting my bumpers maded with a winch and tire carrier for the rear so the springs will drop from the weight. it did on my TJ. i got it aligned today and the esp light went off.
