This Slam Specialties Analog Air Ride Kit for the BMW E9X 3 Series & E8X 1 Series is a basic, no-frills setup that allows for individual 4 corner and paired controls of your air suspension. Great for someone who doesn't want presets or wants a more old school for their setup.
This kit will not work with OEM shocks. The Air Lift lower control arms require the use of M3 rear shocks.
