Do not paint the item before test fitting
Minor adjustments, sanding, or trimming may be required for optimal fitment
Professional body shop installation is strongly recommended

Manufactured from high-strength injection-molded polypropylene, the bumper offers superior flexibility, durability, and impact resistance compared with traditional fiberglass alternatives.
