I believe you can put springs and shocks... I would get all the stuff you need from a local junkyard out of a Ford Expedition this way you will be able to do it with no problems.
Is there a way to put air in back shock off a ford expedition
Replace the shocks, or struts if equipped.
spring struts
Yes you can.
if i was to fix suspension by adding shocks, i would use air shocks to compensate for the air ride
Air shocks allow the vehicle to ride smoother than regular shocks. Also, it helps the car carry greater weight over longer distances than regular shocks.
Replace the shocks with standard shocks. just be sure to turn off the air ride switch located behind the rear drivers side wall poanel
Many companies sell conversion kits to convert the air ride sytem to shocks. Click the link to see one.
As of 2014, there are a few places where one can get rear shocks for a 1994 Chrysler New Yorker with air ride. This can be purchased at Auto Zone and O'Reilly's.
1995 Buick riviera is not equipped with "air ride" type suspension. It is, however equipped with air shocks and coil springs. The air shocks are filled by a compressor in the rear of the undercarriage just in front of the gas tank. If you have an air leak, replacement of the air shocks and/or line kit may be in order.

I think they have air ride shocks in the rear not the whole suspension.
