Designed for straightforward installation, it is a direct replacement part that delivers uncompromising quality, structural integrity, and a flawless factory-style finish for your vehicle.Product Advantage
1. Superior Material & Impact Resistance
Engineered with premium, injection-molded thermoplastic polypropylene (PP), this bumper delivers exceptional durability. Its high tensile strength (over 22 MPa) and notch impact resistance ensure it can absorb minor impacts without cracking, effectively protecting the vehicle's core structure. This advanced material is also approximately 30% lighter than traditional materials, contributing to better fuel efficiency without compromising safety. It is designed to perform reliably in extreme temperatures, from -40°C to 80°C.
2. Precision OEM Fitment Guarantee
We guarantee a perfect, hassle-free installation. Each A21-2804600-DQ bumper is manufactured using original CAD data and precision molds, ensuring dimensional accuracy within ±1.2mm of factory specifications. This eliminates the need for modification, ensuring all mounting points, sensor holes, and light apertures align perfectly. Our commitment to fitment is backed by a 98.5% first-time fit rate, as verified by our technical partners, saving you valuable time and labor costs.
3. Advanced Anti-Corrosion & UV-Resistant Finish
The bumper undergoes a multi-stage finishing process. It starts with a phosphate anti-corrosion pre-treatment, followed by a high-adhesion primer and a final coat of automotive-grade acrylic polyurethane. This system, combined with premium UV-inhibitors, provides over 600 hours of salt spray resistance (ASTM B117 standard) and exceptional protection against fading and chalking, ensuring the color match and glossy appearance last for years.
4. Rigorous Quality Control & Certification
Every bumper must pass a stringent 15-point inspection checklist before shipment. Our quality assurance process includes checks for surface defects, dimensional accuracy, and coating thickness (measured at 90-110 µm). Furthermore, our manufacturing facility is IATF 16949:2016 certified, the international quality management standard for the automotive industry, guaranteeing that this part meets the highest global standards for performance and reliability.
5. Optimized for Safety and Sensor Integration
This bumper is designed with modern vehicle safety in mind. Its internal structure includes engineered crumple zones to help manage impact energy. Furthermore, it features precisely molded pockets and brackets for a seamless fit with parking sensors and rear radar systems, ensuring that critical Advanced Driver-Assistance Systems (ADAS) function correctly post-installation, maintaining the vehicle's original safety integrity.

Product Operate Guide
For a successful installation, we advise having this bumper installed by a certified professional. The process typically requires specialized tools and takes approximately 1.5-2.5 hours for a qualified technician. Before installation, carefully unpack the product and inspect it for any transit damage. Ensure all original mounting brackets and energy absorbers are intact. The bumper is designed as a direct bolt-on replacement; however, a post-installation calibration of parking sensors is highly recommended to guarantee optimal performance and safety. Always refer to official vehicle repair manuals for precise procedures.
