3. The devil is truly in the details. Raising the cab and bed are a snap. Controls, connections, and plumbing that go from body to frame must be accounted for and dealt with so everything functions as it did before the body lift was installed. To avoid problems, we recommend checking steering shafts, gas filler tubes, wiring, and brake lines for available slack before unbolting and lifting begin. If everything seems OK, lift the body in increments, checking the components for available slack. If a component seems stretched too far, see what might cause the binding. Unbolt or disconnect as needed to avoid irritating and costly parts breakage. Installing a longer component is sometimes necessary if the stock item won't stretch enough. If your truck uses an engine-mounted fan, the radiator must be lowered to line up with the fan. Skip this step and you'll risk frying your motor from lacking airflow through the radiator. An alternative to lowering the radiator is to use a radiator-mounted electric fan such as a Flex-A-Lite.
