Keep the hood closed, take a 1/2" socket and look on the side of the headlight assembly and you will see a plastic nut sticking out to the sides of the truck, turn them either way and watch the headlight to see which way you are going. But count the turns so you have a reference point, I have been adjusting them down 2-3 full turns.(I work on a fleet of 100 units and everyone one of them are too high.) Also double check your cab and rear axle suspension heights to make sure they are correct. Good luck!!

Yes, we have bent the bracket that holds the rod down a little bit to raise the cab but that will make it stiffer. Try checking your frame suspension ride height, tire pressures, etc.

Good luck!

bending the bracket is not the correct way of adjusting the suspension. you can loosen the bolts on the ride height valve and adjust the height that way.
