Why OEM Parts Matter for the Mercedes AMG G-63
For a high-performance icon like the AMG G-63, using Original Equipment Manufacturer (OEM) components is non-negotiable. Every factory part—no matter how small—has been engineered to fit, function, and last in the unique environment of your G-63.
For example, the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Black OEM A4638805703 A4638805803 was designed specifically for this model, ensuring seamless fitment and precise protection. In contrast, generic or aftermarket alternatives may lack exact dimensions or the same high-gloss finish, risking both function and aesthetics.
Moreover, only OEM parts maintain the vehicle’s original engineering intent, which in turn preserves warranty coverage and keeps resale values strong. After all, nothing matches the peace of mind that comes from knowing what’s under your G-63’s skin is pure Mercedes-Benz.

OEM vs Aftermarket: Why Original Wins
Many owners ask if aftermarket parts can measure up to Genuine Mercedes-Benz quality. Let’s compare them point-by-point and see why OEM always comes out on top for your G-63.
Firstly, OEM mudguards like A4638805703 and A4638805803 are produced with the exact high-gloss standards demanded by Mercedes AMG. Aftermarket suppliers often use cheaper finishes or imperfect molds, resulting in misalignment or even paint mismatches.
Similarly, genuine parts are subject to strict quality assurance testing for fit and durability. In contrast, aftermarket products can introduce variables that increase installation headaches, rattle, or premature failure.
Furthermore, only OEM parts keep your Mercedes validated for authorized warranty claims. Any issues linked to aftermarket modifications might void coverage and cost you dearly in the long run.
Meanwhile, original factory parts reinforce your car’s resale or trade-in value by assuring future buyers everything is factory-correct—a major advantage on the luxury market.
Installation Tips and Maintenance Best Practices
Installing the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Black OEM A4638805703 A4638805803 is a process designed for precision and ease. Still, following best practices will ensure your new parts look—and perform—as intended.
For example, always thoroughly clean the mounting area to remove grit or old adhesive. This helps your mudguard seat flush against bodywork and maximizes adhesion.
Moreover, have your installation hardware reviewed and, if needed, replaced with new OEM fasteners. This step prevents premature wear and rattling.
In addition, check the alignment of each mudguard before fully tightening the fasteners. Even small shifts can impact appearance or coverage.
To maintain that pristine gloss black look, use a mild automotive shampoo and avoid abrasive cleaning pads. Microfiber cloths keep the finish shining without scratches. Periodically inspect seals and mounting points to catch any loosening before it becomes a problem.
