OEM vs Aftermarket: Why Original Wins
There’s a huge temptation to cut costs with third-party aftermarket parts for your G-Class. However, only original, brand-new Mercedes parts guarantee the look, feel, and safety you deserve.
In contrast, aftermarket mudguards, exhausts, and covers may not fit as precisely as their genuine counterparts. Therefore, fitment issues can lead to annoyances like whistling, unwanted vibration, or premature wear. Moreover, aftermarket suppliers often use varying materials, colors, and designs that don’t align with the AMG aesthetic or Mercedes-Benz engineering philosophy.
OEM parts, such as the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Silver OEM A4638805703 A4638805803, benefit from Mercedes’ exact tolerances, proprietary finishes, and official testing protocols.
- Protect your vehicle’s warranty—no exceptions.
- Enhance resale value by keeping your G-63 in “all original” condition.
- Ensure safer, longer-lasting performance across all driving conditions.
- Match AMG-specific design for authentic appearance and branding.
- Trust longevity, as OEM parts must survive Mercedes’ harshest tests.
Meanwhile, replacing key parts like the Mercedes AMG G-63 Exhaust System LH & RH with mufflers Silver OEM A4634901504 with non-genuine alternatives can lead to compatibility problems, higher emissions, and a loss of signature AMG acoustics.
Installation Tips and Maintenance Best Practices
Although some Mercedes owners enjoy DIY projects, many G-63 components demand professional installation for ideal results.
For example, ensure you have correct factory torque specs and use only Mercedes-approved fasteners and tools. Meanwhile, always confirm the part number matches your vehicle’s VIN before purchase or installation.
Similarly, when installing the Mercedes AMG G-63 Spare Wheel Cover Silver OEM A4638981700, clean the wheel and contact areas to avoid trapping dirt or grit that could mar your finish over time.
Furthermore, regular cleaning with pH-neutral soap helps retain the gloss and luster on your mudguard extensions and wheel cover. Avoid abrasive polishes or pads that can degrade the OEM finish.
