    Question Level Ride Shocks

    I want to replace the rear air-level ride shocks on my deVille 1980,
    They have those air-hose attachemtns,
    When looking on Rockauto and a few more, the only one that quality most are the AC Delvo 504-511
    Which have air-ride leveling support, but the lower mounting on the picture found on google for thi Ac Delco partnr. shows different, on the old ones the lower mounting is just a long thread which a nut goes on.
    And the top mounting seems OK on part no 504-411 (2 small bolts trough a bracket on top of the Shocks)
    So did not found a right part no with Air Support and the right lower mounting type.

    Anyone can shed a light on this ?

    Personally I'd do away with the air ride rear suspension if its giving you trouble. You can get a set of replacement springs from a similar vintage olds 98 or Buick Electra and a set of conventional shocks. I'd recommend new springs, never know how much sag those old junkyard springs will have. This will still give you that nice soft Cadillac ride but with none of the trouble of the auto level feature.

    I got rid of the auto level on both my '78 and '95 Sedan Deville`s after the original air shocks leaked oil.I then had "passive rear shocks" installed.Honestly---they feel 95% the same as the air ride even with the existing rear springs.I`m very picky about my softer/floaty Caddy rides and i`m satisfied with the results.It`s nice to "not" hear the air ride motors,that inflate the shocks,too--and no more extra drain on the batteries either.
    Too each their own though.If i had the deep pockets to repair the original air rides,i probably would have since it is a very nice Cadillac luxury feature when everything works properly.
