Review on Firestone 2579 Air Helper Spring by Pedro Hague

I installed this on my 17 Ram 3500 Cab Chassis 4x4. I believe they are for 2WD but I installed them on my 4x4 in about 2 hours and only had to drill 2 new holes on each side. I unbolted and removed the factory fenders, drilled 2 new holes and installed the airbag. Very simple, cheaper than other kits for some reason and works great. I have a Knaphiede box full of tools and sometimes I'm towing a 14kg trailer and airbags are a must. Air them to about 85 pounds when I have a trailer, about 40 pounds without. I should have them, I had them on my last truck for 12 years (same setup) and they worked great.
