Could you use airbags to replace SLS?
Just dreaming of a project I may do "someday" and thought it would make for a cool subject.
I know where I can get a low mileage 240D motor (think its Euro engine) with like 85K miles, and also a 4 speed manual tranny. All I would need it a clean wagon that needs a drivetrain. What I'm wondering is... could the SLS be removed and sold and then replace that with a small airbag system for the rear? Dave

I just wonder if there is room for the bags....
Little air compressor, little tank. I know it wouldn't be the same as SLS but it may be a simpler system.

Check out Lance's conversion thread. It did not reach a successful conclusion.

Just took a look under my 82 and they put the shock in through the spring so I don't see any place for the air bag to go.

But airbags would take replace the spring, using mounts that were already designed to take those stresses and take the actuators/struts out of the picture all together. I've got no proof that bags would work, just pure conjecture However there may be some suspension geometry issues that I don't know enough about.

Definitely wouldn't be a bolt-in application. Don't give up hope yet, squall, these are "someday" projects for us. Someday I'll have the time and money to figure it out

Aren't all aftermarket Air Shocks built for leaf-spring type suspenssions?
The spring geometry in the W123 and T123 calls for an extremely long spring and the lateral space around that spring is very tight. There is no space for the AirShock to expand laterally and the axial space available would require a very creative mounting. Now on the front the problem would be ever worse with all the steering hardware criss-crossing. However this is reallly an upgrade I would like to see somebody achieve.

Not necessarily so. The Firestone Ride-Rite air bags I put on my Class C motorhome were there for supplementary (and variable) support; to replace the leaf springs would have required fabricating locating links and other suspension pieces. |

Full airbag suspensions are common in hotrod and muscle car applications so I don't see why one couldn't be modified to replace an SLS rear (or all four corners for that matter).

Tony @ Prestige Auto in Houston installed air bags on an 82 wagon with good results. He sold the car and don't believe the buyers had any issues with it. He replaced a bad sls.

you can get shockwaves.. a strut and airbag combo.. but air bags suck.. the ride will be soo floaty since the suspension geometry is always changing
