Push Bumpers
Effect On Air Bag Deployment
Different push bumper designs may each have different deformation characteristics in a crash
situation that may or may not affect the deployment of air bags. Without the benefit of crash tests
on vehicles equipped with push bumpers (there are a number of different styles available), it is the
opinion of Ford Motor Company that installation of some push bumpers could affect the timing of
the air bag deployment. Use of a push bumper that mounts solely to the vehicle’s bumper should
not have a significant effect upon air bag deployment.
Effect On Weight Distribution
The balance and weight distribution of a vehicle is carefully planned to achieve optimal stability
and handling. Push bumpers can change this weight distribution by adding excessive weight to the
front of the vehicle. There are many different styles of push bumpers available. Depending on the
mounting and weight of the push bumper to be installed, it could have an adverse effect on the
handling of a vehicle. Always verify the vehicle ride height after the addition of a push bumper. For
additional information, refer to Section 1: General Information in this guide. Adjust the ride height if
the measurements are not within specifications.
Airflow
The engine cooling system on a vehicle relies on correct airflow through the radiator to keep the
engine at its correct operating temperature. When adding a push bumper to a vehicle, make sure
this airflow is not obstructed, especially when lights and sirens are mounted on the push bumper.
Reduced airflow could put additional strain on the cooling system and shorten the operational life
of related components. During the installation process, keep the placement of components away
from the grille area of the vehicle.
