Anyone know what this is ?

Just a bit of extra NVH pad to dampen road noise coming from the air outlet right behind the jack.

The roadside assistance kit I mentioned is the $59 one that does not have a picture on the Ford accessories page. The “commercial” kit is $219 would likely never be considered as potentially standard equipment.

I googled yes number you gave and found a page with a picture of the $59 kit. It looked to be way thicker (+6") than the pocket on the back of the seat. Included a bunch of stuff including jumper cables which looked like a good fit by itself, without all the other things.

This may be my all time favorite thread. The hilarious thing is that after all these comments, we still have no clue as to the purpose of the thing! And as someone said, there is a reason for it being there.

A good mystery brings out the crazies, happy to have contributed something worthwhile to the community . . . or not.

In another thread we discussed that there is no "seat belt" indicator for the person sitting in the center of the back seat. Maybe the Lariat provides an extra impact cushion for said "center passenger." I have an XLT. My truck isn't fancy enough for that kinda fluff.

@fordvideoguy can you please ask the Brand Manager. Inquiring minds must know, We are having issues sleeping at night thinking about this.

I think it is where youn hide your Ford Maveric Oreo Thins included in the Lariat Lux Package.

I pulled the rear seat back down to check on the jack location and noticed a weird bulge on the back side of the seat back stuffed with felt like material. This has no obvious purpose. Anyone know what it's there for? Emergency pillow? There are no dents in it that would indicate that it's pressing against something on the rear wall. Near as I can tell the only thing in that area of the wall is a couple of wire bundles. I'm stumped.

Does it keep the seat from rattling when it's in the up position? Remove the padding, put the seat up and drive around to test it.

Like fart and nobody knows. Do they have this for the front seats also.

Hey wait a minute, I think I might have figured it out. If you look closely at picture #1 the "Pillow" is positioned such that when the seat is closed upright the "Pillow" gently covers the cabin vent on the back wall. Might just be an insulation barrier from allowing cold/hot air from creeping back into the cabin from outside?

Do you have a sunroof? Being that it's so close to the air relief vent it may be there to deaden the "whoomp-whoomp-whoomp" noise from the vent while the sunroof is opened and the door windows are closed.

No sun roof. Just the sliding rear window.

But why would it be on Lariat but not on other models? Since Ford says the Lariat has additional sound insulation, maybe it is there to thwart false advertising charges. Doesn’t have to actually do anything. They can argue that any insulation anywhere in the truck deadens sound to some extent and since It is only in Lariat the advertising is truthful. But they wouldn’t be that devious, would they? Certainly not that smart.

All Lariats have this. It’s on my F250 Lariat as well. It’s for rattles and noise reduction

edit. Has to do with avail subwoofer

Exactly. By it's composition and positioning, it appears Ford is deploying a classic HEVI acoustic dampener to implement a horizontally explicit vertically implicit (HEVI) and split-explicit time integration scheme.
With this approach, a divergence damping term is added as a final adjustment to the horizontal velocity at the new time level after completing the vertically implicit portion of the time step. In this manner, the divergence used in the filter term has exactly the same numerical form as that used in the discrete pressure equation. Analysis of the dispersion equation for this form of the filter documents its stability characteristics and confirms that it effectively damps acoustic modes with little artificial influence on the amplitude or propagation of the gravity wave modes that are of physical interest. Some specific aspects of the implementation of the filter in the Model for Prediction Across Scales (MPAS) are discussed, and results are presented to illustrate some of the beneficial aspects of suppressing acoustic noise.

I understand you were likely trying to be brief to break-down the basics in layman's terms, but would like to supplement only that its key that the HEVI dampener is contained in the malleable logarithmic casing, or pouch, as without parametric containment, the dingle arm actually amplifies acoustic side-fumbling.

Hey now, y'all cut that crap out. I ain't be comin' here for brain stuff. I just wanna read 'bout folks complaining about not gettin' their trucks yet.
