Liftgate height - how tall should it be

Midwest · Mar 12, 2025

I'm trying to figure out if my liftgate sits too low. 2017 yukon XL. I am 5'9" and hit my head on the sides and just barely clear the center. This seems super low. It seems to operate normally; quiet, smooth etc. When its open fully, I cannot push it up any higher.

Can anyone get me a measurement from the ground to the locking mechanism or to some reference point on the door?

I'm 6'3" and I can walk around under my liftgate without any issues.

Depends on if you’re lowered or stock height. Also you could disconnect the shocks and see if it goes higher but be careful and don’t drop it on your head or you’ll be mad at me.

It’s possible someone replaced them with some that are too short and aren’t allowing full opening because they’’re at the end of their length.

@Rocket Man makes a great point in that perhaps, you have the wrong lift struts on the truck.

Height is also adjustable using the knob on the headliner

I did not know that. I did find a link from GMC on how to do it.

That is news to me, as well. I learn something new every day.

Thank you all for the replies. I should have mentioned that this is a power lift gate. Stick height

Did you see that you can adjust the height it opens on your vehicle? Post #5 mentions it, and in post #6 I left you a link to see how to do it. It labeled itself as “ site maintenance” but if you click on it, you’ll see how to adjust the height. Sounds like it’s set to only open 3/4 of the way.
