Truck is leaning to drivers side

Hello. This is a common thing with the S-series trucks. What you're looking for is and adjustment bolt, not a bar itself. It's in the image below. If memory serves, 1 clockwise rotation equals roughly a half inch lift. My suggestion would be to jack the truck up, turn that bolt 1 full turn, then go for a short ride. Maybe a mile or 2. Then remeasure and adjust accordingly. Keep going until it sits the way you want.

Hope this helps.
