Having a hard time finding suspension parts for a 92 Custom Cruiser. Are they compatible with the other b-body suspension parts or are there differences?

Caprice, Impala SS, Roadmaster.

I have a pair of Hotchkiss rear lowering springs to sell...

All of the springs are compatible, with all B body cars, but the Impala springs are 1 inch shorter to start with. You can safely go 2 inches all around. You will have to remove one 0.030 shim from each stack for every 1/2 inch you drop the front, to compensate for increased negative camber. If you do not, your tires will wear out on the inside edge. 

When measuring the drop, before you do anything else, measure from the top of the rim to the bottom of the wheel opening on both sides, and write it down. After installing the springs measure it again, and subtract the second from the first for your drop. The springs tend to catch on the inside of the hole that the spring is supposed to go through (you may find it easier to unbolt the bushings as well as the spindle). Get new isolators for the top of the springs. Make sure the bottom end of the spring locates between the holes in the lower suspension arm. If the bushing end does not want to go back in the frame, you can spread the frame mounts and when you tighten the bolts they will bend them back to hold the bushing. Put the weight of the car on the suspension before tightening the bushing bolts if you remove them. It might be a good time to install new bushings in the lower arm at this time.

You should have your toe checked before doing a lot of driving.

On the rear, weld a 3 inch piece of exhaust pipe to the center of the upper spring perch, so that the spring will not fall out when/if you jack it to change tires. You can tirwrap the springs to the axle perch for added control. If you have auto self leveling, you must adjust the arm/rod for the sensor, or it will jack the rear up to the original ride height.

I’d like to get a 2”-2.5” drop on it. I live off a dirt road so I can’t get too crazy. So, if the Impalas are an inch lower, does that mean if I get Impala lowering springs that it will be an extra inch lower overall than if I were to get Caprice lowering springs? As far as the rear goes, if the car has self leveling (I’m not sure yet because I’m not getting the car until next weekend) I’d most likely just pull all that out. Any recommendations for sway bars? I’d like to tighten up the handling as much as possible.

The spring drop is measured for a Caprice. Since the Impala is lower already, it will not have the difference advertised for the spring. You must measure the different height for it to be accurate.

Moog 5662 front
Moog CC501 rear

Those are the part numbers you want. No, neither of them are listed as correct for this car, but yes they fit, and you'll like the stance.

As far as sway bars, Hotchkis is the only game in town, or you can get a Crown Vic rear sway bar and bolt that up (there's a writeup somewhere here on the forum).

The Moog springs will drop you a little over 2 inches, and they're much cheaper than "lowering springs" - you can get them from Amazon with free shipping (a big deal on heavy springs).

Free shipping is always a plus. What year Crown Vic for that sway bar? I can look for the write up

Hmmm, I’ll get back to you after I get the car.

Another vote for the MOOG springs. Everyone that installs them is more than happy with the results. Gets rid off the Baja racing look these cars have from the factory. Even better is that they do not require any zip ties or pipe welding because they WILL NOT fall out (when you jack it up) like an expensive lowering spring.

The Moog got my vote. That stance looks perfect!! Thanks for sharing, much appreciated. What shocks are you running? The KYBs

I'm a big fan of the Monroe Severe Service/Gas Magnums

550012 front
550013 rear

Some guys here will tell you they're too firm and harsh, but if the car is lowered IMO they are a perfect balance.

How is the ride quality with the Moog's compared to the stock ride height? I really like the cush of my 91 OCC.

Slightly firmer than stock, but your shocks will do more for ride quality on these cars than springs.

Springs do not have much to do with ride quality until you get to extreme rates. The shocks determine the ride, by damping the spring reflex. Your main issue for ride quality will be the bump stops. You can trim the top inch, or install Z08 stops. Trimming the stops will give you more suspension travel, and with two inches of drop you need all you can get. Loosen all of the bushings to allow them to relax at the new position of the suspension arms.
