I found a set of Firestone airbags that go inside the coil as another option. Ignore my signature I recently bought a 2012 F-350 Lariat to replace my 2007. Thanks for any help.
I have them on my 2006, though I dont plow. They are great. About $90 each from Ford. Takes about 1 hour to change them. You will be glad you did it. Stiffens the front end as well (feels less squirly, and I have had no hint of death wobble since).
Personally I would skip the air bags. I started with 5,200LB coils, then went to 6,000LB coils (snow plow prep), and then went to 7,000LB coils. They are perfect for our truck camper!
