I’ve got a low millage 75 eldo convert and need some advice on new shocks ?
Ps thanks to all for advice on my
Last post regarding convertible top motor /relay  turns out the motor ground was loose.. nice when the fix is easy like that

Front , back, all 4?

[macdaddylong]

Yes they are probably original .. so probably all4 ..
How hard to install new ones ? I have accesss to a lift ..
Also what type should I consider ?

[Dave Shepherd]

I try and use KYB, heavy duty for the front for sure.  You have air shocks in the rear, you may have to do some air line adapting as oe shocks are no longer available, but I think Monroe may be available.

I have a theory that Monroe and Gabriel no longer make air shocks for these, what you get now is old stock so don't be surprised if you end up with air or oil leaks in a fairly short period of time.

On a 1972 Eldorado with a bad air compressor, I went to standard high quality rear non-air shocks and it was fine.  Understand everyone frowns on this practice, but to me it is worthwhile.  The rear is lite in these Cadillacs and full fuel tank and rear seat passengers can mean a weight variation in the rear of 500lbs or so easy.  The reality is most of the time the gas tank is over half full and no one is in the back seat, so the load varies almost never.

Do not go to the air shocks with manual fill.  That means it is another thing you have to deal with, automatic is best.

If your compressor remains operational it may be worthwhile to maintain the ALC and find the air shocks, but some plumbing will be required.  Do not use NOS, as they will probably leak.

Not everyone frowns, I have the parts prepared to do the same on
my 79 Eldo.  Given the improvement with KYB shocks in front, I
can't wait to see how much they help in the rear.  A spare set of
rebuilt and painted rear arms are there with KG5573 shocks, I wonder
what I will need to do about the touring type springs to get level? 
My measurements indicate these shocks are a perfect fit, though
no one else had a clue what non lift would fit. 

Fronts are KYB KG4531, a vast improvement. 

However finishing my house conversion to high tech mini-split
heat pumps will need to be finished first.  Bruce Roe
