The Camco Curved Leveler is a simple way to level your vehicle by giving a tire up to 4 extra inches of lift. The honeycomb design makes the leveler lightweight but durable. The drive-on curved design allows you to only drive on to as much height as needed, then chock the leveler at the exact right height. The included chock has non-slip rubber grippers on the bottom. | CAMCO Curved Leveler and Wheel Chock
