The Luverne Impact Shock-Absorbing Rear Bumper Step is a reinforced steel bumper equipped with spring-loaded shocks integrated into the mounting brackets. It is ideal for delivery vans and other work vans that frequently back into loading areas. As the van backs up, the bumper is designed to protect it against collisions with guard rails, pylons, or even other vehicles, absorbing impacts up to 5 mph and saving the vehicle from costly frame damage. The bumper also has an integrated stepping surface to give the driver safe, ergonomic access to the rear cargo area.
