Proper wheel travel?

[PARAGON]

You can crank up the torsion bar adjustment bolts to get more height in the front end. You just need to get it aligned again if you do that.

Check how much "rake" you have front to back. Measure the distance from each fender to the ground to see if the front is sitting a whole lot lower.

Also, you can have the service tech (or you do it) call a Hummer service tech and find out what the correct "z height" should be. That is the adjustment you are looking for.
