Why OEM Parts Matter for the Mercedes AMG G-63
Genuine Mercedes-Benz parts are purpose-built. When you choose the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Black OEM A4638805703 A4638805803 or the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss White OEM A4638805703 A4638805803, you ensure 100% compatibility with the unique contours of your vehicle.
However, using factory-engineered components guarantees optimal durability and seamless aesthetics. AMG precision means no rattles, no gaps, just perfect alignment and finish.
In addition, only OEM parts carry the full Mercedes warranty, supporting your car’s long-term value. Factory parts help you maintain the original look—critical for authenticity, warranty adherence, and eventual resale price.
Key OEM Parts Categories and Specifications
Let’s focus on the exterior trim and body panels crucial for both protection and style:
- Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Black OEM A4638805703 A4638805803
- Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss White OEM A4638805703 A4638805803
- Mercedes AMG G-63 Front Lower Bumper Gloss Brown
These mudguard extensions and lower bumpers are engineered to factory specifications.
For example, each part number—A4638805703 and A4638805803—references Mercedes’ precise design and material formulations. The gloss finishes (black, white, brown) use high-grade OEM paint systems for consistent, fade-resistant shine.
Meanwhile, all mounting brackets and attaching points align perfectly with the G-63 body shell. No drilling or modification is needed. Thus, you maintain OEM anti-corrosion protections and preserve structural integrity.
Similarly, the Mercedes AMG G-63 Front Lower Bumper Gloss Brown uses impact-resistant composites, meeting Mercedes-Benz crash safety standards, and integrates perfectly with sensors and surrounds.
- Rear LH Wheel Mudguard Widening – Gloss Black or White
- Rear RH Wheel Mudguard Widening – Gloss Black or White
- Front Lower Bumper – Gloss Brown
Therefore, using these specific OEM parts not only keeps your G-63 visually stunning, but also ensures continued safety and road-worthiness.
OEM vs Aftermarket: Why Original Wins
Aftermarket suppliers attempt to replicate Mercedes styling, but they lack the precision and longevity of original parts. Only the OEM Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Black OEM A4638805703 A4638805803 and its color-matched White counterpart guarantee a perfect, seamless look.
Consequently, aftermarket wheel arch covers may warp or discolor faster due to inferior plastic or paint formulations. Seals and alignment often fall short, causing water ingress or unsightly panel gaps.
Furthermore, many aftermarket lower bumpers struggle with sensor integration or strength. As a result, any DIY fitment risks compromising both appearance and protection.
When you opt for original Mercedes-Benz parts, you’re choosing quality engineering, premium materials, and a direct warranty guarantee.
Installation Tips and Maintenance Best Practices
For a flawless result, follow OEM guidelines for fitting the mudguards and bumper panels. Always test-fit before final securing. Use genuine Mercedes fasteners to avoid stress points.
However, avoid modifying mounting holes—this risks moisture intrusion and voids your warranty. Where possible, install in a dust-free environment to keep gloss finishes pristine.
For upkeep, regularly clean with pH-neutral shampoos and microfibre towels. Gloss finishes resist UV, but periodic waxing will maximize longevity and show-car shine.
In contrast, cheaper plastics or aftermarket paints may yellow or peel far sooner, demanding premature replacement. Thus, OEM panels make for smarter, lower-maintenance ownership.
