OEM load-leveling system

I've recently discovered that my OCC has the OEM air shocks and compressor system. The shock bladders are blown and I don't think the air supply system is working either.
Are these systems worth trying to repair, or is all this stuff obsolete? There is a rather elaborate looking wiring harness and electric level switch.... I'm thinking it would be cool to restore this stuff and run a pair of air-lift bags and some good non-gas shocks.

When they are working, they are a great idea. When I used to hang my boat trailer on the hitch, I'd start the car & watch the thing re-level itself within a minute or two. Cool as hell.

Just get the air lift bags, and a new compressor. Mount the compressor in the rear storage compartment so it stays dry and it will last a long long time. Mine works great.
I have a gauge and a switch to adjust air pressures. No need for the factory switch, but it would be handy!

By comparison, Big-Rig air-ride leveling is much simpler because the leveling switches are actually air valves with links to the axles..... If my wagon had a ready supply of stored air, I probably would convert to a big-truck leveling system.
Another possibility is to use the stock leveling switch to operate a new compressor and release solenoid.
I have the gauges and switches in my dually and find it kind of a PIA to keep the 5lb minimum manually.

I have the Airlift 1000 bags and the kit I originally bought for my GMC Safari. The kit has the gauge, compressor, manual switch, manual air release valve and it came with an automatic switch that adds air if below 5 PSI and lets air out if above 35 PSI. I never have to touch it unless I want to change the ride height. Granted it is not self leveling.

I would say it depends on what you do with the car. If hauling often either payloadvor trailer a self level would be nice. I have three wagons and its broken on all of them. The car with the class three hitch and lt1 I put cargo springs which have more coils than stock, but when empty the rear end is higher than normal giving the car a rake and costing me fuel economy I would guess

But it looks cool, so it evens out.

sprocket, did the cargo coils come out of a blue wagon ???

Having a rake does not necessarily decrease gas mileage. The higher rear tends to equalize the pressure under the car from front to rear, and possibly lower the turbulance. The top is still smooth, and will not make an appreciable difference in drag.
