What airbags to use for 1999 f-350 dually with DJM 3/5 kit

I just lowered my 1999 f-350 and i need to know if anybody knows a airbag kit for towing that will work with my truck being lowered 5" in back actually it made it 6" but i called a couple companies and they said with the leaf spring being so close to the frame none of them had one so has anyone installed them on a 99-up ford dually and what one is it i need to tow around 13500 i still have my bottom overload springs in but i want it to not sag in the rear thanks!

I used the firestone helper bages on mine and I have towed a two place with a 48 chevy and a 86 crew cab dually (TwistedDually) from the site doing 80 plus on the freeway all the way to ITB several years no prblem.

A slamair should fit

hey twistedcooter nice truck thats the same thing i want to do put 24's on mine someday is that the kit you have the 3/5 and what firestone airbag kit did you use how did it fit with the little amount of room thanks

Thanks low99, it is 3/5 on 22s and it is just the helper bag kit from firestone that I used and it fits in just fine, it mounts on the side of the frame and on top of the leaf pack, you get a good amount of lift for heavy loads. I will get some pics on how much lift I get and try to get a pic on the side of the frame.
