Introduction
Nothing stands out on the road quite like a Mercedes AMG G-63. Its blend of muscular luxury and off-road capability makes it a top choice for discerning drivers. However, discerning owners know that only OEM parts truly maintain the G-63’s legendary performance and resale value. In this article, we dive deep into key OEM components: the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Gray OEM A4638805703 A4638805803 and the Mercedes AMG G-63 Spare Wheel Cover Silver OEM A4638981700. If you value authenticity and lasting durability, you need to know why these exact-match factory parts are essential.
Why OEM Parts Matter for the Mercedes AMG G-63
Genuine parts are a must for a supercar of this caliber. Mercedes-Benz engineers design every part to deliver seamless compatibility and uncompromising quality. When you choose OEM—like the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Gray OEM A4638805703 A4638805803—you’re making a commitment to the G-63’s structural integrity.
Meanwhile, aftermarket components often miss crucial tolerances or aesthetic details. For example, a factory-made Mercedes AMG G-63 Spare Wheel Cover Silver OEM A4638981700 won’t just look right—it will fit perfectly and function as intended by AMG engineers.
Moreover, using OEM keeps your G-63’s warranty intact. In contrast, non-genuine parts could void crucial coverage. That’s a risk no true super-SUV fan should take!
Key OEM Parts Categories and Specifications
When it comes to the G-63, even the smallest body trim elevates form and function. Let’s break down these premium parts and their unique technical attributes.
Rear Wheel Thread Mudguard Widening Gloss Gray (A4638805703/A4638805803)
These left and right-hand (LH & RH) mudguard extensions widen the G-63’s distinctive fenders. The OEM part numbers—A4638805703 and A4638805803—guarantee the best fit for the 2018+ Mercedes AMG G-63.

The Mercedes AMG G-63 Spare Wheel Cover Silver OEM A4638981700 is more than just a style upgrade. This precision-molded cover protects your spare tire from road grime and UV rays. Its metallic silver finish complements other OEM trim parts, ensuring a seamless exterior aesthetic.

- Durable, weather-resistant coatings
- Precision color-matched to factory G-63 paint codes
- All factory mounting hardware and seals included
- No modifications needed—bolt-on installation
Additional Essential Categories
In addition to wheel and exterior protection, Mercedes-Benz OEM parts cover:
- Suspension and chassis components
- Braking system hardware
- Electronics—sensors, cameras, and lights
- Interior trim panels and seating modules
- Drivetrain and exhaust system pieces
However, body panels, wheel arch trims, and covers remain some of the most visible indicators of genuine AMG quality.
OEM vs Aftermarket: Why Original Wins
Let’s be honest: you wouldn’t put bargain tires on a G-63, so why risk aftermarket body parts? Genuine Mercedes-Benz components—such as the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Gray OEM A4638805703 A4638805803—are engineered to exact automotive tolerances.
Consequently, OEM parts deliver not only perfect fit but unsurpassed longevity. Aftermarket alternatives may save you a bit up front. But poor fits, mismatched colors, or subpar plastics can result in rattles, leaks, and (worst of all) compromised resale value.
For example, original Mercedes components come with manufacturer-backed corrosion protection, impact credentials, and—perhaps most important—the prestige of a verifiable Mercedes-Benz part number.
In addition, using original factory parts preserves both your driving experience and your SUV’s warranty status. Many Abu Dhabi and Dubai Mercedes service centers may even decline non-OEM parts work on warranty vehicles. So original is always the best investment for serious owners!
Installation Tips and Maintenance Best Practices
Installing the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Gray OEM A4638805703 A4638805803 is a straightforward job for trained technicians—or advanced DIYers with the right Mercedes-specific tools.
However, always use the detailed Mercedes installation guide included with factory parts. Remember to clean all mounting surfaces thoroughly before installing new mudguards or covers. Thus, you guarantee seal integrity and long-term finish quality.
Furthermore, regularly inspect your mudguard extensions for trapped dirt or road salts—especially after an off-road adventure. These components are durable, but routine cleaning preserves that trademark gloss gray shine. The same applies to the Mercedes AMG G-63 Spare Wheel Cover Silver OEM A4638981700; wash it using only approved car-care products to avoid micro-scratches.
In contrast, aftermarket mudguards may need repeated adjustments or may not seal properly, leading to underlying corrosion. Stick with OEM for peace of mind!
