Need help / measurement from someone with a stock H2
 

Truck is in another shop still having problems getting correct ride height after lift installed.

Can someone measure the distance from the center of the rear axle/hub to the bottom of the black trim around the wheel well. Measure straight up.

Thanks in advance.

25 1/2"

Thank you!

GM has a couple of specific size blocks they put in between the axle and frame when calibrating to be perfectly level it but they are not needed. You just have to block the rear up in some way to make sure its at the correct height and is level. I have a Tech 2 and I just used a couple of jacks under the rear of the frame, got it perfectly level and at the right height, then did the calibration which sets that particular height and level as the reference.
