The bumper system in your Nissan contains several major components that help it diffuse and distribute the force of impact from low-speed collisions. The "bumper" that you see is just a cosmetic piece, but tucked underneath, your vehicle has a bumper impact bar, bumper impact absorber, and several mounting brackets to keep your bumper securely held in place.
On your Nissan, the Bumper Impact Bar is a rigid metal bar that is designed to diffuse impact energy during a collision. If your Nissan is hit in the bumper area, the Bumper Impact Bar may help to absorb and distribute some of the impact energy into other parts of your vehicle frame that are engineered to collapse in a way that can protect vehicle occupants (these areas are called "crush points"). The Bumper Impact Bar can also decrease the severity of the shockwave that the vehicle occupants are subjected to upon impact.
Given that the Bumper Impact Bar is a vital crash safety component, you generally don't want to perform a temporary repair on a damaged or cracked bar. Instead, replace the Bumper Impact Bar entirely to help ensure your bumper system and vehicle frame can work as they should in a roadway collision. Shop Nissan Genuine Parts for a replacement Bumper Impact Bar that's engineered and manufactured for your exact model and year. Then, make the trip to your local Nissan dealer for installation done right.
