Yes, on my 2018 Exp Max XLT I installed the factory gas tank shield, factory tranfser case plate, Raptor transmisson plate and 2 RCI steel plates for under the engine and intercooler.
I like the Raptor skid plate because it is belly shaped and hides the catalytic converters better and is a driect bolt on but I expect the trans plate from RCI is thicker and stronger.
The factory stuff I chased down on the internet a piece at a time to get best prices from various Ford dealers. They seem to offer random discounts so just search part by part and watch the shipping it makes a big difference. Could not get the little oil-change cover that goes on the Raptor trans pan. It was out of stock everywhere and they jacked up the prices so I plan to make my own out of 1/16 steel.
I think I screwed up when I ordered the older style RCI plates for the 2007-2017 Expy / F150 09-14. I had to do some modifications to get them to fit and will explain.
The front plate that goes under the intercooler comes with two heavy Z shape brackets and was able to place them right on the frame next to the intercooler brackets but did have to drill new bolt holes in the brackets, I only used one bolt here instead of two. You might have to clearance the edge of the bracket to get it to fit against the intercooler bracket.
This was the only modification for the front of the front plate. It is very heavy duty with nice key hole slots for easy removal and durable finish, it did not scratch off even with all the messing with it.
The plate under the engine at the rear has slots and bolts into the same holes as the original transmision cover no problem.
The problem comes where the front and engine plates meet in the middle. On the Expy they bottomed out up against both the steering rack and the front differential.
My solution was to get a 12in. piece of 1.5 square tubing 1/8in. thick, drill two holes in it for the bolts, placing it between the engine cross member and the plates.
This provided plenty of clearance between the plates and the steering and differential and spaced perfectly with the framing on each side where it juts down from the engine cross member.
I drilled two holes in the front plate near the back edge and sloted them. Now I can loosen the 4 bolts of the front plate and slide it forward in the key holes to remove it for changing oil filter etc.
Have to admit this part turned out really slick. In the front of the under engine plate I also drilled and sloted the holes where it overlaps and joins with the front plate unter the 1.5in. tube spacer.
All and all I'm very happy with the outcome but did not plan on doing this many modifications. It took me a bit to work it out but reality is the modifications just consisted of drilling holes in the front brackets, drilling and sloting holes at the rear of the front plate, then drilling and sloting the front of the under engine plate, obtaining a 12in long piece of 1.5in. x 1.5in x 1/8in thick piece of square tubing and drilling two holes in it. I also had to get some longer metric shoulder bolts to go through both plates in the center where they meet and through the square tubing into the existing nut clips in the engine cross member. BTW, the framing under the Expy is impressively built.
I think the two bolts were 70mm or 2 3/4 long and got lucky and found them at the local hardware at $5 each which actually is inline with what the dealer charges for similar bolts.
The RCI plates came with good hardware including the nut clips that go into frame slots and metric shoulder bolts but they are zinc coated and not galvanized like the factory ones.
I am very pleased with the quality of the RCI plates, they are way more heavy duty than I will every need. RCI must have had them in-stock because they arrived in just 3 or 4 days of ordering them. I suspect the newer style F150 plates would fit the Expy better but still not sure. I am due to change the oil soon and will take pictures if anyone wants to seem.
