RIDE HEIGHTS

The front (FS) and rear (RS) suspension ride heights are provided as a basic tool to determine the overall height of the
cab, height of exhaust components, and frame heights. The heights are all calculated from the centerlines of the axles,
please be sure to include the tire radius dimension to determine overall height. Note: the frame rail height itself will not
affect the overall height as all components are located from the bottom of the frame rail.
