2007 yukon denali front bumper fitment/ gap issue.

[ny_summit]

Hey everyone I have a 2007 yukon xl denali that I purchased just about a year ago. I installed some aftermarket headlights yesterday and it made me realize I have a decent size gap under the headlight and between the bumper. Also catching my attention was the gap between my hood and bumper. I compared to some other pictures I found online and indeed it seems I have a larger gap than others. Is there anyway to raise the bumper up a bit? Or is the bumper itself sagging from over the years of heat?
The photo circled is my yukon the others are for comparison.
From my knowledge (carfax) it hasn't been in an accident and don't see any signs of it being in an accident.

Open hood and look at where the bumper/grill is bolted and see if you can loosen the bolt and pull that up some.

You can also try lowering the rubber hood stop/bumper on that side that's located behind the headlight

I know the 6(?) bolts across the front allow for a bit of some adjustment

Some adjustment but since the bolts fasten to J-nuts, it's going to move some even after tightening. I have a new bumper cover and still have that little bit of sag. New OE headlamps too.
