Introduction
If you own a Mercedes-AMG G-63, you understand the pride and thrill that come with such an iconic machine. Preserving its imposing presence and extraordinary performance demands only the best, especially when it comes to visible elements like the Mercedes AMG G-63 Rear Bumper Cover Black OEM A4638851902 and the Mercedes AMG G-63 Front Lower Bumper Black Gloss.
However, many owners overlook the vital importance of using OEM (Original Equipment Manufacturer) parts for both restoration and upgrade projects. As a result, you might compromise safety, reliability, or outright authenticity if you choose non-genuine alternatives. In this article, you’ll discover why genuine AMG G-63 exterior parts shine above all others, how they perfectly fit your G-Wagon, and the steps to elevate your vehicle’s curb appeal while protecting investment value.
Why OEM Parts Matter for the Mercedes AMG G-63
For the world’s most recognized luxury SUV, attention to detail is everything. The AMG G-63 embodies legendary Mercedes engineering and performance, so your exterior parts should do the same.
Meanwhile, genuine components like the Mercedes AMG G-63 Rear Bumper Cover Black OEM A4638851902 offer benefits far beyond basic looks. Maintaining your vehicle’s original aesthetics, structure, and aerodynamic balance depends on exact fitment and factory-quality construction.
Furthermore, OEM parts are engineered specifically for the G-63, providing seamless compatibility and preserving factory warranty. In contrast, aftermarket options may use inferior materials or methods, leading to poor alignment and reduced lifespan. Consequently, only Mercedes-Benz original replacements safeguard your AMG’s unique DNA and resale value.
Key OEM Parts Categories and Specifications
Mercedes-Benz engineers develop a holistic system, where each part interacts with the vehicle as a whole. Understanding the main part categories can help you make the right choice. Two critical exterior components for the G-63 are:
- Mercedes AMG G-63 Rear Bumper Cover Black OEM A4638851902: This piece anchors the SUV’s aggressive rear profile. Its ABS construction offers robust impact resistance while maintaining the factory matte-black finish for OEM authenticity.
- Mercedes AMG G-63 Front Lower Bumper Black Gloss: This lower front valance pan enhances the G-63’s signature stance and airflow optimization. The gloss finish blends perfectly with AMG’s sporty design language, while integrated sensor and vent cutouts ensure a plug-and-play installation.

Similarly, both these bumper covers align with parking distance sensors, active safety equipment, and AMG-specific mounting brackets—ensuring every contour and function matches the vehicle’s original state.
Beyond bumpers, genuine Mercedes-AMG parts for your G-63 also include:
- Engine and drivetrain reinforcements for optimal power retention
- Factory shock mounts and suspension arms for unrivaled handling
- Steel body panels and side moldings for corrosion prevention
- Braking upgrades using Mercedes-spec calipers and rotors
- Interior trim—leather, carbon fiber, and electronics matched to VIN
As a result, sticking with OEM ensures every detail—visible or hidden—reflects the G-Wagon’s demanding standards.
OEM vs Aftermarket: Why Original Wins
In contrast to generic replacements, OEM components such as the Mercedes AMG G-63 Rear Bumper Cover Black OEM A4638851902 deliver unmatched reliability and appearance.
Moreover, Mercedes-Benz rigorously tests each part for strength, fit, and durability. Every bumper undergoes simulated crash, vibration, heat, and UV exposure exams. This level of scrutiny ensures long-term safety and protection for your AMG G-63 occupants.
Aftermarket covers may claim universal compatibility, but subtle differences in mounting, finish, or dimensions commonly result in fussy installations or noticeable gaps. Similarly, paint mismatches and weak fastener points threaten both the look and structure of your SUV. Genuine parts, however, guarantee flawless performance with every replacement.
Thus, choosing OEM parts over aftermarket means:
- Perfect fitment with original fastening hardware
- Preservation of advanced safety technology
- Certified paint thickness and UV resistance
- Full compatibility with sensor and camera systems
- Certainty for warranty or insurance claims
In addition, original parts help maintain your Mercedes’ certified pre-owned eligibility and highest possible resale value.
Installation Tips and Maintenance Best Practices
Installing an Mercedes AMG G-63 Rear Bumper Cover Black OEM A4638851902 or Mercedes AMG G-63 Front Lower Bumper Black Gloss is best accomplished with precision and proper planning. While it’s possible for experienced DIYers, professional Mercedes-trained technicians guarantee that all sensors, mounts, and bodylines align perfectly.
Therefore, if you plan to perform the install yourself, always consult the official factory service manual. Have the necessary specialty tools ready, including panel poppers, torque wrenches, and protective fender covers to minimize the risk of scratches.
For example, follow these steps for a straightforward installation:
- Disconnect the vehicle’s negative battery terminal to safeguard electronic components.
- Elevate and secure the G-63 for underneath access (jack stands or a lift is ideal).
- Remove the plastic and metal fasteners along the lower edge and wheel arches.
- Gently unclip the original bumper cover, disconnecting any integrated sensors or lamps as needed.
- Test-fit the new OEM bumper cover, securing connections, and double-checking sensor alignment.
- Fasten all hardware in factory-established patterns and torque values.
- Reinstall the battery connection and test sensors and lights before road use.
Similarly, after installation, apply a mild, pH-balanced car shampoo and a microfiber towel to clean the bumper finish. Avoid abrasive compounds, as the OEM finish is factory-cured and requires gentle care.
Furthermore, inspect mounting bolts and sensor functions regularly, especially after impacts or heavy off-roading. This keeps your AMG’s looks and safety systems restoration-ready at all times.
