Product Advantage
1. OEM-Grade Fitment Guaranteed by Precision Engineering
Achieve a seamless, factory-original fit with our A21-8403760-DY fender. Each panel is engineered using OEM CAD data and undergoes rigorous dimensional checks with a tolerance of less than ±1.5mm. This precision manufacturing process eliminates the common issues of gaps and misalignment, ensuring a hassle-free installation. By reducing adjustment time by up to 40% compared to generic alternatives, this fender helps professional installers improve workshop efficiency and guarantees a perfect finish for a premium repair every time.2. Superior Durability with High-Strength, Anti-Corrosion Steel
Constructed from premium cold-rolled steel with a minimum yield strength of 350 MPa, this fender is built to withstand impacts and resist deformation. It features a multi-stage anti-corrosion treatment, including a phosphate zinc layer and a premium electro-coat primer, providing over 500 hours of salt spray resistance (ASTM B117 standard). This robust construction ensures long-term protection against rust and corrosion, significantly extending the component's service life even in harsh climatic conditions.3. Optimized Surface Finish for Streamlined Painting
We understand that surface preparation is critical. This fender arrives with an expertly applied electro-deposition primer that offers superior adhesion. The surface roughness (Ra) is controlled to within 0.8-1.2 micrometers, creating the ideal profile for paint bonding. This optimization can reduce primer sanding time by approximately 30% and ensures a flawless, OEM-quality topcoat finish that matches the vehicle's original color and gloss retention perfectly.4. Rigorous Quality Assurance for Consistent Reliability
Every A21-8403760-DY fender is subject to a comprehensive 12-point quality inspection protocol before shipment. Our failure rate is maintained below 0.2%, a benchmark that underscores our commitment to reliability. This meticulous process checks for dimensional accuracy, surface defects, and coating uniformity, giving you the confidence that you are receiving a part that meets the highest industry standards for safety, performance, and longevity.

Product Operate Guide
For a successful installation, we recommend a professional mechanic handle the process. Begin by carefully removing the fasteners on the wheel arch liner, front bumper, and door jamb. Support the old fender before fully detaching it. Align the new A21-8403760-DY fender using the factory-designated bolt holes, starting from the top. Hand-tighten all bolts initially to allow for micro-adjustment, then torque them to the manufacturer's specification (typically 8-12 N·m) for a secure and rattle-free fit. Finally, connect all side markers and lights. Always test all functions before finalizing the installation.
