Do these things really work?

I have heard some say it helps mpg,and some say that it just deflects bugs.

I have heard all sorts of claims. But I remember back in the day every dually had one made from aluminum

I never used one of the huge aluminum wings, but the high top shell I had on my truck for a long(9/10yrs) time, would show the bug line, following a long tow trip. With it, I got 1.7 to 2 mpg better, and the lower bug line was very obvious after I had to remove the shell.
There is a larger amount of products like the one in your picture, than I thought, but it has to be as high or very close to the trailer roof line, to do much good, IMO.
Your results may vary.


You have to put in the effort, to get anything out of it.

I'm thinking about a nose cone for my trailer. It's 100% square corners.

Have you priced them? The one I got quoted was $750 if you mean the bubble type for the front.

Yeah, that's what I saw too...if I wait long enough we'll be junking out our 26' box truck and I might steal it off there.

I haven't tried my connections with used trailers and van bodies yet, but I'd probably pay $500 for one. Confused

I'm 100% convinced that is the best way to help my rig, high MPH is a MPG killer with that trailer. Nearly -1 MPG when I exceed 61 MPH rather than staying about 58.

I agree they do help. In my case I just didn’t think I traveled enough for it to pay out.

Always thought those aluminum wings on the roof of a dually looked ridiculous.

That’s why it’s going to be removable

Me too. Seen many but never heard of them actually doing any good... Only person I ever knew that had one said his fuel economy was the same with or without.....

Toad1 (Jok) wrote an article about those years back. He had performed experiments using them on his motorhome and trailer. I don't remember the results other than they helped keep the ass end of his equipment cleaner.

The only thing the deflector does is keeps the bugs off the front of the trailer. The air surface is still ~=. A cone on the front of the trailer only reduces your wallet. If you want to reduce drag, look at the back of your trailer, not the front. Picture a raindrop.

We saw a bunch of long haul guys heading to and from Phoenix with deflectors on the cab , cones on the upper , ground effect shear on the lower sides and tail deflection to break the vacuum on the rear . Does it work?? I sent a message to both my long haul racers, Billy who works for Bobby Ray and Danny -Hoffman Racing. Betting they can shed some light. Wind was bad from Blyth to Livermore.

The Aerodynamics are all the same. Called drag. Technology has come so far advanced with eliminating or cutting wind speed drag. Costing MPG loss. Even the advanced wheel cover drag options available. Covers that cover the entire rim.

This sums it up. As an example on the left GUI.

Funny thing, when i have to get under these things with the side ferrings.... inhale.

LOL! I'm guessing they wouldn't spend if it did not work.
