Adding After Market Air Ride to Cab on 1986 W900.

I think it depends how much you're willing to spend.

If you know someone that's a good fabricator it's possible to have someone fabricate a set up so that your mounts are at the front of the cab.

I don't know how other trucks do it but I like the idea that Freightliner has that they pivot on a bushing. If you had the part from a Freightliner that bolted onto the frame if someone could do the fabricating on the cab for you then you'd be able to use air ride.

The parts are probably relatively inexpensive. I don't know what someone would charge to do the fabricating for you.

 

Before you go to all of that work, install an air ride seat. You can find used seats for a hundred bucks or less. All you really need is the base. I have a Ford F-700 box truck, an old one, it rides like a brick. I swapped in bucket seats from a similar year F-150, then converted the drivers seat to air ride with a base I had left over from replacing a complete air ride seat in a previous truck.

 

Myself I wouldn’t. Those older cabs need a substantial subframe under them to be suspended. I saw a beautiful ‘86 359 destroyed that way. Took a nice truck and turned it into a nightmare of rattles, squeaks and sheared off rivets. Drive an older spring ride truck for a few hours. Yours will seem a lot better without touching it.
