    Comments about Monroe Max-Air Air Shock Absorber:

    Installed a set of these shocks on my Cadillac 2 or 3 years ago. They fit and worked fine but I knew they were very close to each exhaust pipe. I even wrapped the pipes with heat sheilding tape! A few weeks ago I noticed that one side of the car was very low so I tried to fill that shock and air was excaping. After inspection I found the shock boot had worn thru against the exhaust pipe. I removed the old shocks, altered the pipes for clearance, and installed the new shocks. If you install these be certain you have clearance all around!

      Monroe does not list an air shock for my 56 Cadillac but these are the right length and stroke and they fit perfectly!
