No shocks, just the front srpings and rear level arms. There's only one available spring set for the X5's with rear air suspension- probably a street-sport setup. Supposed to drop 1.2" and only raise the spring rate in front 10%, and about 7-8% in the rear as a result of the airbag doubling over a bit more on itself which has the same effect as increasing the firmness of the airbag.
