I was under the hood last night installing my illuminated emblem and I noticed that on the passenger side at the top of the shutters there's one missing. It appears there should be one there but not sure if it's not there for a reason or it just got missed at the factory. Anyone else have this or just myself? I have the 3.0 duramax if it makes a diffence. Thanks!

My 3.0 doesn't have that fin either. Looked at another 3.0 on dealers lot and it doesn't have it either. I wouldn't get too concerned about it as I think they come from factory that way.

I wouldn't worry about it. That 1 fin missing is not going to change things one way or another. It's not like your gonna gain 1mpg by getting them to replace it.

We still haven't heard from anyone that has a 3.0 with that fin in place. 

Seems like MIA is more likely, but it could be part of cooling system differences for that engine. 

 

Let us know what you learn!

Will do! Hopefully someone with the 3.0 can chime in as well!

Same as others found. Just quickly looked at mine without taking anything apart, there is a space at the top on the passenger side.

If all the 3.0s are like that it is for a reason. Might be a component that needs that gap at high speeds when the shutters close for cooling or air flow. I wouldn't worry, probably normal

Which engines have shutters?  I don't see any on my 2019 LTZ with the 6.2L

Thought they all had shutters to shape the truck like an aerodynamic brick at high speeds. Have to look carefully through the front grille to see them edgewise; they are open when vehicle is stopped.

I've looked very carefully and there is nothing but a big empty void between my grill and the radiator.

There may be other reasons, but as far as I know, max trailering package trucks don’t get shutters. Mine doesn’t have them.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.
