Why OEM Parts Matter for Other Other
When it comes to replacing critical exterior components like the Mercedes AMG G-63 Front Lower Bumper Gloss Silver, only OEM parts ensure guaranteed compatibility and maintain your vehicle’s showroom-grade appeal.

Similarly, these OEM pieces safeguard your warranty, support resale value, and maintain the full intended performance and safety offered by the G-63.
Key OEM Parts Categories and Specifications

- Mercedes AMG G-63 Front Lower Bumper Gloss Silver
- Mercedes AMG G-63 Front LH & RH Wheel Thread Mudguard Widening Front Matte Silver OEM A4638805503 A4638805603

Delving deeper:
- Front Lower Bumper (Gloss Silver): Designed for a perfect precision fit, this bumper keeps aerodynamics and visual flow seamless. The gloss finish matches original AMG aesthetics, protecting against scratches and chips with a durable, factory-applied clear coat.
- Wheel Thread Mudguard Widening (Front Matte Silver, Left & Right): Built from robust materials to withstand both urban and off-road environments, these fender flares widen the track for better road debris protection. Their matte silver finish resists fading, keeping your G-63 looking sharp for years.
Furthermore, by using OEM body panels, you maintain every line, angle, and aesthetic feature exactly as Mercedes intended from the factory, ensuring you never compromise on iconic styling or engineering integrity.
OEM vs Aftermarket: Why Original Wins
In contrast to aftermarket parts, OEM parts are the clear choice for any G-63 owner serious about maintaining brand standards and protecting long-term value.
Aftermarket bumpers and mudguards often lack precision fitment and may introduce uneven gaps or align poorly with existing trim.
Furthermore, using OEM components like the Mercedes AMG G-63 Front Lower Bumper Gloss Silver ensures the part you receive underwent the same development, testing, and quality control as the original. Third-party pieces rarely match Mercedes-Benz’s stringent testing for impact resistance, paint durability, or corrosion protection.
Similarly, choosing Mercedes AMG G-63 Front LH & RH Wheel Thread Mudguard Widening Front Matte Silver OEM A4638805503 A4638805603 over non-genuine options preserves the warranty and aligns with Mercedes’ own safety and design standards.
Therefore, the superior fit, finish, reliability, and value retention offered by true OEM parts is unmatched.
Installation Tips and Maintenance Best Practices
Proper installation of exterior parts is essential for maintaining the Mercedes-AMG G-63’s performance and look.
For best results, always start by confirming the OEM part numbers match your model year and specific G-63 variant.
In addition, use only factory-recommended fasteners and hardware to secure each component. Avoid overtightening, as AMG body panels are engineered for precise stress loads to preserve safety and finish.
If replacing the bumper, ensure sensors, cameras, and other electronics are properly reconnected for advanced safety system functionality.
To preserve the finish on the gloss silver and matte silver elements, wash with pH-neutral soap and use a microfiber cloth. Avoid harsh chemicals or abrasive materials that can mar the OEM coating.
Furthermore, always visually inspect after installation for alignment and ensure fasteners are torqued to Mercedes specifications. A quality job ensures not just a perfect look, but weather and impact resistance as originally designed.
