For owners passionate about preserving the iconic G-Wagon look and performance, selecting genuine, factory-new OEM parts is essential. In this article, we dig deep into why these exact Mercedes AMG G-63 mudguard widenings matter, how they outperform alternatives, and where you should source them in the UAE.
Why OEM Parts Matter for the Mercedes AMG G-63
First and foremost, OEM (Original Equipment Manufacturer) components ensure your G-63 retains its factory standards for safety, fitment, and performance. You simply cannot underestimate the difference genuine pieces make—especially for high-value vehicles like the AMG G-63.
However, using OEM parts ensures your SUV maintains its luxurious appeal, keeps its resale value high, and protects existing warranties. For example, even a minor exterior accessory such as the Mercedes AMG G-63 Front LH & RH Wheel Thread Mudguard Widening Gloss White OEM A4638805503 A4638805603 makes a dramatic difference by seamlessly integrating with the vehicle’s original lines and technology.
Meanwhile, when you fit non-OEM mudguards or fender flares, you risk color mismatching, ill-fitting installations, and—worst—potential rust points or water ingress that erode luxury and integrity over time.
Key OEM Parts Categories and Specifications
The Mercedes Benz G-Class is a masterpiece of German engineering, with every panel and accessory built for a purpose. The mudguards, specifically the Mercedes AMG G-63 Front LH & RH Wheel Thread Mudguard Widening Gloss White OEM A4638805503 A4638805603 and Mercedes AMG G-63 Front LH & RH Wheel Thread Mudguard Widening Gloss Silver OEM A4638805503 A4638805603, are not just cosmetic—they serve functional purposes that protect your investment.
In addition, these mudguards are precision-molded from highly durable plastic composites, engineered by Mercedes-Benz to withstand the punishing environments for which the G-Class was built. The gloss white and gloss silver finishes are sprayed at the Mercedes factory using premium-grade paints to match the exact OEM color codes of the G-63.
Furthermore, the OEM part numbers A4638805503 and A4638805603 guarantee you are getting the real article, crafted to merge perfectly with your G-63’s wheel wells, fender edges, and mounting brackets.

OEM vs Aftermarket: Why Original Wins
For many car enthusiasts, the temptation to select aftermarket alternatives is ever-present due to lower upfront costs. However, the long-term value of OEM vastly overshadows initial savings.
For example, the Mercedes AMG G-63 Front LH & RH Wheel Thread Mudguard Widening Gloss White OEM A4638805503 A4638805603 guarantees meticulous fitment—even on the overengineered AMG G-63—where aftermarket parts often fail to match panel curvature, bracket alignment, or body color accurately.
In contrast, aftermarket mudguards may introduce subtle but frustrating issues such as imperfect seams, extra wind noise, or incompatibility with the stock mounting points.
Furthermore, Mercedes’ own stringent quality control ensures every OEM mudguard meets the highest standards for resilience, finish, and color fastness. The correct gloss white and gloss silver versions eliminate the “almost right” but ultimately noticeable mismatch that happens with generic accessories.
Key Reasons to Choose OEM Over Aftermarket
- Preserves manufacturer warranty by using authorized parts
- Ensures perfect fit and proper protection
- Enhances resale value by maintaining originality
- Outperforms aftermarket parts in durability and finish longevity
- Avoids problems caused by incompatibility or subpar materials
Meanwhile, those who demand the best for their AMG G-63 recognize that choosing original always wins—in both engineering and aesthetics.
