I have a 2003 F150 FX4 that I would like to be able to work harder. I can load about 1.5 tons of wood, coal etc. but the wheels are probably close to rubbing. What is the best way to increase the suspension and haul a decent weight without my bumper dragging.

Thanks

 

I'd add Firestone airbags to the rear suspension.

trade it in on a 250/350.... Make sure your upgradeing to LT tires if you are carrying heavy loads for long distances, or for extended periods.

If you want to hole 1.5 tons of anything in the bed, you bought the wrong truck for the job. Air bags do not increase your hauling capacity. The tires, wheels, frame, bed, and axle components were engineered as a system and rated accordingly. Installing airbags will reduce the squat, but will not, under any circumstances, increase the truck's ability to haul anything.
