Front air dam ??

[Ont240]

Is there an air dam add on for 07 Tahoe LT 4x4?
I'll try post pics.
Mine has a thin support abs bracket at the bottom. Appears to be part of the bumper cover. Is it missing something. Bought the vehicle used like this. Need to improve aerodynamics. Has any one tried to create a diffuser at the back?

Improve aerodynamics? hmm not a whole lot you can do
maybe get a hybrid front end clip, lower it, remove the roof rack.

Yep, I think you're missing the stock front dam/lip thingy..

More Information for VARIOUS MFR GM1092208

does it clip in at the top and then gets fastened in a couple of locations.
I could add to its depth with a rubber strip and reduce the air going underneath.
Maybe remove the cross bars when not using the roof rack. Still used as a hauler sometimes!

Use the lower bits from an '08-'13 Tahoe Hybrid, like Doubelieve above.
For a budget approach, trim lawnmower edging to the desired shape.

Only difference I noticed without the little spoiler is that over 120 mph, the nose gets a little light. Otherwise, negligible MPG change.

I removed mine because I kept hitting it on rocks.

No difference in mileage, due to many other factors. Heavy foot included.

@iamdub has to watch his, sometime lays frame with it, can't find the damn pic he posted.

As @Doubeleive stated, there really isn't much that you can do to significantly improve the aerodynamics of these ~5800 lb. rocks.

Any little bit helps. Installed this morning.



Trip to Florida later this year towing a loaded car trailer will give me some idea.
