Visual Fitment Reference The orange-highlighted part in the diagram above shows exactly where this outer brace installs—at the outermost front corner, linking the frame horn to the bumper’s side flange. More than a positioning aid, it’s a load-bearing support arm that ties the bumper to the frame. This reinforcement helps the bumper maintain shape during light contact and protects adjacent fiberglass from stress or distortion.
Because Details Matter C3 bumpers rely on proper bracing to stay aligned and absorb real-world vibration or minor impact. Without this brace, your bumper is unsupported—more likely to crack panels or shift out of place. This reproduction restores the structural tie-in that GM engineers intended.
