Hi everyone,

Back when the new Job 2 trucks came out, they had a new, taller air dam. I ordered one from my parts guy. I've had it in my garage for what seems like months now. Finally, I put it on. If it can help me save one mpg, it will help. If you plan on doing this to your job#1 truck, here's what I know (start to finish):

• The original job #1 air dam is secured by two bolts on each end and the rest of the fasteners are "pop up" type plastic fasteners. You need a metric #8 wrench for the bolt heads. Its a tight fit to get your fingers and wrench in there. This was the hardest part of the uninstall, and re-install.
• Remove the two bolts from each end - save them.
• The plastic fasteners holding the securing the rest of the original air dam simply pop up from the bottom. Use a phillips head screw driver or your fingers to simply push up on these. They simply pop out. There are 11 of them. You will not need these on the new air dam.
• The new taller air dam has the metal clip type fasteners with threads. I was not about to pay $6 ea for the bolts at the Ford dealership so I went to Lowe's. I found these were the closest fit. They're tight but fit. Hillman M6-1.00 x 25 Body Bolts. $1.39 for a pack of two. You can find them in the aisle where all the small packs of nuts and bolts are sold. (the slide out drawers) These take a #10 metric wrench.
• Next, you want to get this thing threaded and started. You'll have to figure out a way to get the air dam to hang so you can begin tightening this puppy down. I began manually threading each of the new bolts into the threaded clips. I kept them loose until I got them all threaded.
• I used the original bolts on the ends as before. Another 5 minutes or so.
• Once you get it aligned, start tightening the bolts down.
• Stand back and admire your work, then go inside and cool off.

The entire job took about 30 minutes.

 

Is the Job 2 Airdam about $100?
Thanks for the step by step!

 

Yep, $100. I think that's correct. They're proud of it.

 

So did it help with mileage any?

 

Nice write up. I guess we'll have to wait to see how the mileage compares.

 

My dealer gave me a break on the valance (spoiler) and it cost me $77. Outer bolts have a 8mm head on them- I took off a plate held on by three 13mm bolts that gave me better access to them. Got the 10mm head body bolts at Lowes and they worked great. Pretty easy to put on- makes the OEM valance look pretty small!
I'm sure now I'll get 30 mpg

 

 

I just installed the Job #2 air dam and I wanted to add somethings to Cham198's post.

Though you do not have to re-use the plastic fasteners, I found that there are holes in the Job #2 air dam and the bumper where 4 or 5 of the plastic fasteners from the Job #1 air dam can be re-used. 7 bolts are probably more than enough to hold it up but, I figured that 7 bolts plus 4 or 5 re-used plastic fasteners couldn't hurt.

I also found using a plastic fastener to hold up the air dam when starting the installation was a lot easier than trying to hold it up with one hand, while trying to align it, while trying to also screw in a bolt to hold it up for you. Pushing in the plastic fastener was a lot easier than screwing in a bolt.

FYI: I picked up the M6-1.00x25 at home depot for $0.50 per packet of two and $0.06 per washer (1/4" washer if I remember right).

BTW: Thanks Champ198 for this thread, helped me a lot when I tackled this "mod".

 

So did it help?

 

Yes it helps.
I got about 1.5 MPG better.

 

Hmmm so that means my Job2 would only be getting about 7.5 without the big air dam.

1.5MPG increase is very impressive but difficult to comprehend.

 

Haven't noticed any MPG improvement but I think it looks better. Seems like mileage went down a little but so many variables- changed from winter Mobil 1 5-40 synthetic to dino 15-40 summer oil which does seem to make a little difference (down with the dino).
I reused a couple of the snaps in the extra holes as well but it seems very sturdy...

 

I can't detect any measurable improvement. Not saying it doesn't make an improvement, just don't have any noticeable improvement yet for my rig. It's less than 1mpg in savings at this point.

BTW, I did go back and add at least two of the original plastic fasterners back. It covers some holes that look like they needed something there.

 

Just installed the job 2 air dam on my job 1. It's not that hard to do, thanks for the tips Champ198. Anybody know where to get bigger washers? The 6mm ones at Home Depot are a bit smaller, OK, a lot smaller than the original ones. I put the ones I got on for now, but I'm going to have to scout for a bigger washer. I'd hate to have buy 50,000 from McMaster-Carr just to get five.

I'm taking a road trip on Monday that I usually get around 13 MPG, so I'll have to see what I get with the new chin. Even if it only gets me 0.5 MPG, it'll pay for itself on the way to Yellowstone.
