I was changing the oil yesterday in my new to me X ( bought it 3 weeks ago ) and I was just checking it out from underneath when I noticed something that looks not stock. See picture below.

Is this what people refer to as an " airbag " set up? I towed with it for the first time this week and typically on my other X's if I did not hook up the weight distribution hitch, the rear of the truck would sag. This X did not. It also has more of a truck like feel to it when driving it.

 

Yeah thats an air bag system from air ride. Make sure to run at least 5psi in them unloaded

 

Looks like the Firestone ride rite. Look on your rear bumper for air lines. Most put them thru the license plate.

I found one on my front porch today.

 

Yes! I found the valve in the rear bumper near the license plate. Underneath I found the red air lines running to the bags. I checked the valve and they seem to have almost no air in them. What is recommended? 5 psi minimum like suggested above?

 

Yes. 5lbs minimum otherwise from what I understand, the bags can get damaged.

Hopefully yours won't be.

Yeah, anything below 5psi lets the bag be used as a bumpstop jounce and increases the chance of rubbing or pinching a hole in the bags. You can buy replacement bags, but they are not much less than the whole kit. Seems like last time I looked they were in the $115-125 range each. I only gave $300 for my kit.
