Hook up a fifth wheel, a camper or a car hauler and a Super Duty sits down at the back. BOSS rear air bag kits work alongside the factory leaf springs, so you can bring the truck back to level with the load on and let the air out when you unhook.

Each kit page lists its full rating, pressure range and fitting instructions.
Double or triple bellow?
Both mount the same way. Triple bellow bags are taller and give more travel than double bellow bags, so they suit trucks that need the extra reach. For a truck at stock height, the double bellow kit is the usual choice. More detail: single vs double vs triple bellow air bags.
Fitting
The kits bolt on with basic hand tools, with no welding, and most installs take 2–3 hours. Every kit comes with BOSS's fitting instructions. For 2017–2019 trucks there is also our step-by-step guide: How to Install Air Bags on a 2017–2019 Ford F-250 or F-350.
Adjust the air from the cab
Every kit fills from any tire air line through its Schrader valves. To adjust from the driver's seat, add an inflation kit with PX01 in-cab controller ($249), or the universal Auto Pressure Air Bag Controller ($599), which works with any load assist kit and the compressor already on the truck. More options: compressor kits and controllers.
F-250 and F-350 air bag questions
My truck is a 2017 or newer. Which kit? 2017 brought a new Super Duty body with its own kits. The 2017–2019 kits need a 4″ rear axle, so check your axle tag or build sheet. For any 2017+ truck, contact us with your VIN and we'll confirm.
Do the bags replace my leaf springs or overloads? No. They work alongside the factory leaf pack and carry part of the extra load.
How much air should I run? Just enough to level the truck with your load. That lets the whole suspension share the weight.
Does it raise my towing capacity? No. The bags help level the truck when it's legally loaded. Stay within Ford's payload and towing ratings.
