Ram 3500 Air Suspension - How Does It Work?

The Ram 2500 with air suspension has no steel springs, just airbags. The 3500 still uses steel springs but supplements with airbags.

Dupe.

Here is a pic of the as delivered system.




The only way to go with a straight air system is to get the Kelderman Air system. Completely replaces the factory suspension with a 4 link air ride suspension.

Go to ramtrucks.com and you will see the system used.

There aren't any springs according to what I see.

There are still leaf springs. The air bags just supplement them. If you do Google it, you won't find the real system. You will see diagrams of what was proposed and what people were ordering, but not what is being delivered. There was a last second re-design that eliminated the track bar and added half leafs to the front side of the full leaf spring. The Ram forums have more info on this. As for control, it's all automatic. When a load is applied to the truck, the bags inflate to automatically bring the truck back to it's unloaded ride height. It can not be manually controlled.

I was big on this system and considered Ram for my next truck because of it. However, now that it's finally out in the wild, reports say the unloaded ride is no better than the standard leaf spring rear suspension.
