Here are the factors you are going to find.

1 Many are not measuring properly.

2 Many vehicles lean and are not level. Most have axles not perfectly centered under the rear too.

3 It is not uncommon to run across a rear spring to lose it curve sometimes so it can happen and it happened to any leaf spring.

Finally the fuel tank is near the center inside the frame so it will have only a small effect. You also have the exhaust on the other side.

Now if you bought it used look for a secret panel and white powder before you get pulled over. Don't laugh I have seen it happen to second owners.

GM specks that ride height measurements be taken with a full tank of gas, so that's not the problem.

My truck (2016 LT) was an inch lower on the driver's side than the passenger side. After driving it about 5000 miles the difference was down to about 5/8 inch. Seems it was adjusting itself. Before I installed the rear anti-sway bar two weeks ago I loosened all six of the rear spring mount bolts. I then measured ride height and found that left to right was equal to as close as I could measure (less than 1/8 inch difference). I bounced the suspension around a bit to settle everything, remeasured to make sure it was still level and retorqued the six spring mount bolts. The truck sets level now. It appears the problem was nothing more than binding spring bushings. I suspect that is the cause of most of these problems. It's an easy fix that can be done in about half an hour, even if you're an old codger like myself.

Unless your leaning on the front as I am. I'm a half inch lower on the driver side front...and about the same on the driver side rear.

Mine had a lean on the front as well. It was not as much as the rear but I don't remember the exact measurement though. That went away as well.

This is crazy i checked my 2016 diesel 4x4 it is off 1/2'' down on the front drivers side 7/16 down on drivers side rear. Truck has 1000 miles on it. Perhaps GM was thinking of using this truck in stock car racing, turning left all day long. Sad I might have to try and put one of those 1970s rubber coil spring spacers in there.

with a quarter tank im 3/8" lower on drivers front and rear.


on my first gen colorado, when i lowered it i used 1 extra preload ring on the front driver strut and that actually helped with the rear lean as well.

Ill post an update after i get these on, im hoping that bringing the front driver to level will bring the rear closer to level as well.

might be a few days though as i threw out my back this morning, fingers crossed...

I am going to put a 2'' rc lift on the front 1'' block on the back. This coming up week. I will drive it around then recheck. Doubt if there is any diff. right now 7/16'' low left rear 1/2'' low left front. I looked at the struts and the distance to the strut boot looks too close or I would put in rubber spacer in the spring on the left side. Prolly end up putting in washers in the body mounts on left side. Fuel in tank or no fuel does not make much diff.

Did the lift it is the same or worse, leaning on the left side.
