Since putting bigger tires on the 3 tons of fun, I don’t have the clearance for over the spring bags, So the hunt began. 

 

I went with firestone F2220 bags, they go inside the frame and and ment for a 2001 dodge 3500 cab and chassis. according to firestone, etrailer, and a few other company’s they shouldn’t work. But they do with minor modification.

 

ended up elongating the airbag mounting holes by 1/4” and they you can clear the lip on the frame that is bent downward. If you wanted to you could grind out this one spot where the inward nut sits (which is the reason to modify) but to each there own. I didn’t want to cut the frame.

Once up they work great, I will be towing with them this weekend and hopefully will be able to tell the difference between without bags and with. 

Hope this helps someone if they have larger tires on a dually also. 

 

 

Wonder if those will fit 2500?

I’m sure it’s possible, the frames are the same I believe. 

I used over the leaf spring kit and modified it to go on axle/frame. I don't think kit above was available, if it was I overlooked it. I didn't shave my frame I just made the extension from few pieces of heavy wall dom tube I had laying around. Kit above looks like would be pretty easy to put on 2500 with little modification.

 

That is cool. mine are mounted to the side of the frame and don't like it so much.

Yhea I didn't care for that design plus I have a goose neck plate there.

I thought about doing that, but between moving  from WA to OK I didn’t want to mess with more fab work than I needed to, already had to finish up the trailer. 
 

but I do like the Square tubing supports you have under the bottom plate, I’m thinking of doing that to mine, after the last few days they have a bit of a sag inward so supports are in the future regardless

Dieselfuture needs to move out west and I stuff his pockets with money if you do work like that.
