Any springs listed for the Caprice or Impala SS will work. Hotchkiss, ST, Vogtland, Sprint, Intrax all make springs that will work.

You'll need to change out your shocks as well. Ask the spring makers what they recommend. You can get rid of your level ride system in the rear by switching to conventional shocks as well. Less stuff to break if you disable the level ride.

You don't need to change the shocks, but if you are going to lower it, it would be a good idea. All of the lowering springs are going to be a higher rate than stock. Also, you can mod the air ride sensor linkage to work with lower rear springs if you want to keep that feature.

we just used to cut a quarter or half a turn off the springs with a grinder. Yes I know it's not 'recommended' but I never had any issues :hide:

Several members used '94-96 Impala SS springs, turns out quite nicely. I have them on my '96 Fleetwood paired with Bilstein shocks.

Here is Destroyer's Brougham with the springs:

^WOW, that looks awesome, makes mine look like it has the Z-71 off road option. Although I have to ask, what is up with the top on that car . . .

Looks sharp! Looks like a kind of Phaeton roof option going on there Destroyer
Slightly off thread (Sorry!) What shocks would you recommend for regular duty on a '78 Eldorado and 79 Coupe deVille? Monroe's? - ordinary or the sensa trak? Was thinking of the Monroe Air Max in the rear for the electronic suspension option

Isn't that a normal top on a '90-92 Brougham?

I was saying that it doesn't match the paint color. I've seen other cars in that same color and the top matched the paint better. Might just be the light/camera playing tricks though.

How low do you want to go? Easy answer is just to get Impala SS springs. Mine are Eibach for Caprice/Impala SS;

The 507 really made it squat considering the springs were for an LT1 :)

Depends what kind of ride you want.

Stiff= Bilstein & Monroe Severe Service

+1 on 96Fleetwood's suggestions. I have Bilsteins on my SS, and Monroe Severe Service on my Wagon. Both are STIFF. Not what one would want if they want a traditional "Cadillac" ride.

will they work if i put lowering springs from a SS on my 83 deville. If not what will work?
thank you

Any shock for a '77-96 Caprice or Impala SS (B or D body actually) will work.

The Bilstein sport and Monroe Severe Service tend to hold up better to lowering springs.

Hello,

It's coming time for my replacement of my shocks on my 86 FWB. I saw this pic a fell in love with the lowered height...does anyone know what brand shocks will drop the front and back shocks this much (or close to it) without losing ride comfort and quality?

Are the rear shocks in this photo that of the original air shocks or were they replaced?..looks like the fronts were only lowered?

Thanks,
Tabz

The coil springs are what is going to lower the car, not the shocks. The shocks only stabilize the spring to decrease the "bounce". With the exception of air shocks which will raise the car slightly when inflated. Get yourself some Impala SS '94-'96 lowering springs if you want to do it right. I put Eibach in my car and it rides like a lowered car. Much firmer but not too stiff. It takes corners a lot better too. You shouldn't have a problem using the original air shocks in the rear. I actually want to put them back in mine. That way you will have a little bit of adjustability if you need it.

Thanks!...I'll have to check em out. What brand shocks are best for the 80's FWB for both the rear air and the standard fronts?

I just bought the cheaper monroe for the front and left the rears in that were there. I don't even know what they are, not air though. I'm on a tight budget and only drive that car on the weekends so ride quality isn't my first concern. I think the level ride will need to be adjusted to compensate for the different height if you're keeping that feature. In the past I've unplugged the power to it and took the bulb out of the dash. You can adjust the height of the rear via the air nozzle on the compressor under the hood. It's not the right way, but it works. On this thread there's a bunch of different opinions on brands of shocks.

This is a really useful sticky from the Impala SS Forum.

Out of curiosity.... being that your fronts are lower, do your front tires ever rub in the tire well when the tires are fully turned in either direction?

Not at all. I forget what size tires they are, but the tread is 10mm thinner than stock. I think 215's? I only got them that way because I got a great deal.

Cadillac advertising of the day showed these cars with a ride height unavailable from the factory. Looks slick.
