Saggy undertray gone for good…

I really wish these held up better over time. It’s super annoying and disappointing.

2020 Lariat FX4 here.

Just realized my 2017 FX4 doesn’t even have one. I’ve got skid plates, but no felt undertray. Hmm.

If your truck’s ever been off-road for more than 5 minutes, the previous owner probably ripped it off. I had to yank mine off my 2022 work truck almost immediately. It’s only held on by a few bolts anyway.

@Om
Do they make one for a 2015? Mine’s sagging just like OP’s.

@Om
Appreciate you sharing this!

I swapped mine for the Raptor’s metal one. It even has a cutout for oil changes. No regrets—worth every penny.

How much did yours cost? I’m seeing metal replacements for $600 online.

I lost mine in the snow last week. Found a metal one on Amazon for $68, and it just arrived today. It even has a hatch for oil changes.

Snow wrecked mine too, but I managed to reattach it with a steel L bracket and some bolts from Home Depot.

Same here! DIY fix for the win.

Honestly, just toss it. It’s mostly there to meet MPG specs for the window sticker.

Replaced mine with a metal one on my Expedition. Way more durable.

What’s the official name for this part if I want to search for a replacement?

It’s called an underbody shield. Avoid the felt ones—they’ll just fail again.

Some folks call it hairy cardboard. Genuine UAW pubes included.

Mine on my ‘21 was barely hanging on until yesterday. Poor design—putting the screw holes right on the edges was a terrible idea.

LMAO, same thing happened to me yesterday. Had nothing but a Leatherman on me, so I just cut it off. Looking into metal plates now.

Still got mine on my 2017. What are y’all doing to wreck these so fast?

Snow seems to be the main culprit.

Yep. Snow and slush soak it, then it freezes and breaks. People constantly tell you something’s dragging. Then you just rip it off.

@Macon
Does it even protect anything? I’ve got the FX4 skid plates.
