Why OEM Parts Matter for the Mercedes AMG G-63
Authenticity is the lifeblood of luxury vehicles like the G-63. Therefore, using OEM components isn’t just a preference—it’s a necessity. Genuine Mercedes-Benz parts guarantee your SUV maintains its powerful performance, iconic aesthetics, and superior safety standards set by the brand.
In contrast, aftermarket alternatives rarely offer the same level of detail or engineering excellence. Similarly, OEM parts are rigorously tested by Mercedes engineers, ensuring they complement the vehicle’s existing systems without risk of compatibility issues. Thus, opting for genuine parts like the Mercedes AMG G-63 Front LH & RH Wheel Thread Mudguard Widening Gloss Red OEM A4638805503 A4638805603 means you preserve your G-63’s factory integrity.

OEM vs Aftermarket: Why Original Wins
Aftermarket parts may seem tempting due to lower prices. However, when it comes to your AMG G-63, shortcuts rarely pay off. Aftermarket panels often use generic molds, lower-grade materials, and inconsistent finishes.
This can lead to improper fitment, rattling, premature fading, or even interference with sensors and safety features. In addition, using non-genuine parts may void your Mercedes warranty or compromise resale value, especially at official inspections or trade-ins.
Similarly, only Dealer Original parts are certified to blend seamlessly with the vehicle’s onboard electronics and ADAS (Advanced Driver Assistance Systems). Thus, whether you’re replacing the Mercedes AMG G-63 Front LH & RH Wheel Thread Mudguard Widening Gloss Red OEM A4638805503 A4638805603 or updating your Mercedes AMG G-63 Front Lower Bumper Gloss Gray, insist on factory originals.
Installation Tips and Maintenance Best Practices
Proper installation ensures you enjoy all the benefits of your OEM upgrades. Therefore, always work with certified Mercedes-Benz or AMG technicians familiar with G-63 requirements. In addition, follow included installation guidelines and use torque specs provided by the manufacturer.
For example, pre-fit each part before securing it, ensuring lines are flush and free of tension. Similarly, protect painted surfaces with microfiber towels during installation to prevent micro-scratches.
After installation, routinely inspect fastener points and touch up any minor chips to maintain a fresh appearance. Use only Mercedes-approved cleaning products to protect the gloss red and gray finishes from fading.
