Another rear airbag option


Recommended Posts

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. 6BBBD109-39E1-4051-ACF0-BDD50C7784E1.jpeg.aef6c00d17d8c9560234f53eb242ad83.jpeg

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

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.

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
