Is it possible to eliminate all 4 sets of springs and replace with something like Kelderman air bags. I wonder what ballpark cost would be if it's possible. That should get rid of a lot of noise and really improve the ride on my 93 W350. It's rough!!

 

The Kelderman I have turns the bottom leafs on the front over and uses the air bags for the work.

The rear uses 2 bags and a linkage system to attach the rear springs to....



If you went CUSTOM... they should be able to build custom links and have it a true air ride system. Without the front spring packs in the way you also could put a crossover steering setup on without having a lift. (no springs to interfere with the steering)

 

Any idea what the damage would be for something like that?

 

$8K to $10K if you had a shop build it. For a custom 4 link front and rear, and all the air ride stuff, bags lines, pumps, tanks, valves ect...
