The heights are all calculated from the centerlines of the axles, please be sure to include the tire radius dimension to determine overall height.

Be sure to check the axle spacing that is shown, as alternate spacings may exist and could change some of the dimensions. The dimensions shown below are the most typical installations, in special cases some hole locations will move. If you are planning on using the holes shown for your body installation, please confirm with your local KW dealer that the drawing below will be the installation used on your specific truck. Ensure that proper torque is used to reinstall any suspension components. See Tables 7-1 and 7-2 on page 7-7.
