• Position on Vehicle: Rear of the vehicle – both left and right bumper bracket mounts that secure the bumper to the bodywork.

• Applications: Ideal when original bumper brackets are missing, bent, rusted or mismatched - essential for restoring correct bumper fitment, vehicle aesthetics and structural integrity.

Properly positioned and secure bumper bracketry is critical for preservation of body alignment, panel gaps, vibration-free mounting and safety. When brackets are bent, missing or corroded, you may observe uneven bumper gaps, rattles, movement during driving, or decreased visual quality. Replacing the brackets with this matched set restores factory geometry, prevents misalignment stress and supports the original appearance and value of your vehicle.

When and why to replace:
• Bumper gaps appear inconsistent, mis-aligned or uneven around the rear.
• Brackets are visibly corroded, deformed or have been previously welded/modified.
• During body restoration, repainting, or panel-repair when the bumper is removed.
• When upgrading to high-fitment standard for restoration or concours-level finish.
• On vehicles where original hardware has aged, corroded or been removed in previous repairs.
