'09 LTZ question

[rogersinsel]

My truck has two servos (looking) on the front frame rails. One on each side. They each have lever attached to them going down toward the ground. I have not crawled under there yet. But does anyone know what they do? Thanks.

Are they by the wheels? I think you might be talking about the autoride sensors and if you are there will also be 2 in the rear.

they are probably the sensors for the autoride since you have and LTZ
