? about rear air bags

[Two Bit]

I'm lookimg at a used F350 dually (just at the add pictures at the moment, haven't seen it in person). It has had rear air bag suspension added. and I have some questions ...

When this is done are any factory springs removed or are the bags additional to the leafs?

They dont increase the GVWR so what is the purpose of them?

I've never dealt with air bags so I'm in the dark.

I have airbags on my F250, and they've really helped the ride- they are more known as "load-levelers", but a side-affect is the rideability. No springs are taken out (in fact, for heavier loads, it's a good idea to add a product such as their Add-A-Leaf System), which an additional leaf. Together with the RS9000X shocks I put on, it's a pretty good ride.

The only thing to worry about in buying an existing TV with one, is "how old". The air lines are plastic (nylon), and unlike us guys, DON'T get better with age!

They are really air springs by design and tey supplement the load carrying capabilities by keeping the truck closer to normal ride height. My last ruck had them and they helped the ride a lot with the 5er on it. Kpt the truck from riding down and hitting the overload springs.

There should be full spring packs on the truck even with the air springs.
