active aero shutters

H1ghlndr · June 23, 2020

I have a 2020 Sierra HD AT4 3500 SRW Duramax built 1/29/20. It does not have active aero shutters in front of radiator - looks like it has the holes for each shutter, but no shutter. Didn't really think about it until watching a YouTube duramax channel with a grille off a 2020 and there were active aero shutters. I have no codes so I wonder if this was intentional from factory?

Do others have (or not) these active aero shutters shutters on their 2020 L5Ps?

Diesels don't have the shutters, gasoline engines only.

Here is the video I saw. This is a 2020 duramax...

From GM: " In addition to the Silverado HD’s larger dimensions and distinctive trim personalities, 2500 and 3500 SRW models are available with active aero shutters for improved efficiency and a taller, more dominant hood line that asserts the trucks’ strength and character."

I don't know about the active shutters, but I have seen his videos before. I could not imagine paying $80k+ (Canadian) for a truck and then ripping it apart like he does...gives me nightmares.

Mine has the shutters, 2020 GMC AT4 with a Duramax, you can see them behind the grille. I had to extract a extra push pin fastener from mine, also found one in the hood scoop drain, someone must of felt generous on the assembly line that day. That or my truck is falling apart....

Is yours a 2500? I am wondering if it is a 2500 vs 3500 thing.

Doesn’t explain your extra ones though

My 2020 AT4HD 2500 Duramax has active shutters.

That's a conundrum for sure. I can't imagine why engineers would put shutters in front of that giant charge air cooler and radiator. As I stated above, my 2020 LTZ 2500HD does not have shutters. I can see where the shutters would fit into the front grill work for gasoline powered trucks but I didn't think any diesels had them. It will be interesting to find out what the thinking is on them.

My 2500 Denali L5P does not have them either. Tied to 5th wheel tow package maybe?

I don't have 5th wheel, but snow-plow and towing as part of 3500. I am wondering if people with no shutters have an option like snow plow prep or something else? Weird that there are 2500s with / without. My initial thesis was 2500 and them and 3500s didn't.

What options do people have with and without shutters?

I don't see them on my 3500 DRW...L5P Denali with 5th wheel package.

I have a 2500 AT4 crew cab, 6’9” bed with the 5th wheel package, not sure about snow plow prep, I would have to check the window sticker.

I have 3500 srw 4x4 high country with 5th wheel and tow package. Mine has them.

This is strange...Those that have them - Are they in the top, lower (below bumper) or both sections of the grill?

I know for the 1500s, options like trailboss/AT4, snow plow prep, max trailering,.... will play into if you will have shutters. It is probably an option that you have on your truck that does not allow you to have them.

ill go back to my side now. lol
