Air bag suspension for trucks question

I have the Firestone air bags(springs)(on the same truck), with a compressor and in-dash gauge. If you are near weight capacity loaded, these bags will keep the truck rear-end even. Ford says it also increases load capacity to a F350. Make sure you get the air distribution equalizer. It helps sway. If you are hauling animals this helps. An added benefit is when not loaded, you can reduce air pressure to about 10 lbs. and get a softer ride than you would with an F350. Another bene. is the Firestone bags attach using existing holes.(no drilling)
