Our laser cut 71-96 Caprice or Impala air bag cups are just what you need to put air suspension on the front of your GM B Body! These are constructed of 1/4 inch steel and are laser cut to be very precise. The upper cups easily bolt in place after removing the factory coil spring and shock. The upper cup slides up into the frame rail where the spring was originally. It is held in place by the center stud that goes through the hole where the shock originally mounted to the frame rail. The lower cups sit in the lower control arm where the factory spring sat and are held in place by two additional studs and nuts. The mounting holes are cut out to allow you to mount these to any manufacturer’s air bags.
