What this part does

The rear bumper reinforcement is a heavy-duty structural crossmember mounted directly to the rear frame rails of the chassis. It sits behind the plastic bumper cover and absorbs the kinetic energy of a rear-end collision, distributing the force to protect the vehicle structure and occupants. Once this bar bends or crushes in an impact, its structural integrity is compromised and it can no longer absorb force correctly in a subsequent collision, requiring full replacement.

Before you order

Inspect the mounting brackets and rear frame rails on your vehicle before ordering. The energy-absorbing brackets connecting this bumper reinforcement to the chassis are designed to crush first, and you may need to source them separately if they are compressed. Compare the part number 8W0807309C to your original bar, as variations exist depending on whether the vehicle is equipped with a tow hitch package.
