Lift amount does NOT equal spacer thickness owing to the suspension geometry. Lift spacer is not equal to the actual spacer thickness. *****Rear Block is 2" thickness 2004-2020 2WD has NO stock block, it will provide additional 2" lift. 2004-2008 4WD has 2" stock block, it will provide NO additional lift. 2009-2020 4WD has 1 1/2" stock block, it will provide additional 1/2" lift. What is a leveling kit? .
