When you're performing a body lift, there are a number of parts which will need to be supporting or repositioning with a bracket. For example, in many off road vehicles the radiator is mounted to the body, so when the body lifts 50mm engine fan is out of line with the radiator, spoiling airflow.
A decent body lift kit should include radiator brackets, to ensure you can align the radiator back to its original position and return airflow to its best, and the kit should also include brackets for any number of other potential uses.
During a body lift, brackets come in handy for many other essential actions, making sure critical components do not move out of the position which makes them fully effective, and making sure parts do not get in the way of each other.
For example, the radiator bottle on some vehicles can get damaged by the air conditioning pulley given the bottle has been moved closer to it - but luckily there's a bracket for that! In situations like this and many others a bracket is the simple solution instead of having to modify or remove parts.
