Introduction
If you’re a proud Mercedes G-Class owner, you know every component defines the legend. Similarly, the Mercedes AMG G-63 Front LH & RH Wheel Thread Mudguard Widening Gloss Gray OEM A4638805503 A4638805603 takes style, protection, and authenticity to the next level.
Therefore, many G-63 enthusiasts want nothing but the very best—especially when it comes to visible exterior additions like wheel thread mudguards. In this blog, you’ll discover why these premium OEM parts surpass aftermarket options and how they help preserve the iconic prestige of your G-Wagen.
Why OEM Parts Matter for Other Other
Moreover, discerning owners know that OEM, or Original Equipment Manufacturer parts, stand for quality and confidence. For example, OEM mudguard widening kits like A4638805503 and A4638805603 are crafted precisely for the G-63’s unique chassis and wheel arches. In contrast, aftermarket alternatives often compromise on fit, finish, and long-term durability.
Meanwhile, OEM parts maintain all manufacturer performance and safety requirements. This means peace of mind for every adventure—on or off-road.

OEM vs Aftermarket: Why Original Wins

Moreover, installing non-OEM parts could void your manufacturer’s warranty and potentially reduce your G-Wagen’s resale value. Similarly, insurance companies often prefer (or require) OEM parts for claims and repairs.
Installation Tips and Maintenance Best Practices
Therefore, installation should always follow the official Mercedes-Benz process. However, even seasoned DIYers appreciate how easy it is to mount these genuine OEM mudguards using prealigned factory holes, fasteners, and tabs.
Meanwhile, follow this basic step-by-step:
- Carefully remove any existing mudguards and clean the mounting surface.
- Align the new mudguard widening with factory screw holes, ensuring flush, exact match with wheel arch contours.

Furthermore, routine inspection keeps these body parts like new:
