I just recently installed the front Rough Country 2.5” leveling kit and my headlights were pointing at Jesus! So I will share how I returned the headlights to the correct angle. This tutorial may be applicable to all 4th generation Dodge Rams.

So here are a few pictures of how to adjust them. CCW adjusts down and CW adjusts up. I turned mine CCW around 2-3 turns to return to stock angle. If you can’t decide the height of adjustment, adjust it and go drive it. You will figure out where it should go very quickly. Alternatively, mark a wall or building with a piece a tape before leveling or lifting your truck.
You can use a standard socket instead of the #20 Torx bit if you don’t have one. It looks like an 8mm socket.
