Why OEM Parts Matter for the Mercedes AMG G-63
For example, investing in original equipment manufacturer parts doesn’t just elevate visual appeal—it’s about maximizing your vehicle’s safety, performance, and market value.
Genuine parts like the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Brown OEM A4638805703 A4638805803 ensure every curve, joint, and finish is identical to what rolled off the factory floor. Thus, you honor the Mercedes-Benz legacy while protecting your luxury SUV’s investment potential.
Meanwhile, AMG’s precise German engineering harmonizes with these factory parts. Without them, you put performance, safety, and authenticity at risk. Protect your warranty and guarantee top resale value by always insisting on original parts.
Key OEM Parts Categories and Specifications
When examining G-Class components, attention to detail becomes paramount. Let’s spotlight why the rear LH & RH mudguard widening panels, finished in gloss brown and marked by part numbers A4638805703 and A4638805803, stand apart.
- Exact OEM fitment for W463 G-63 AMG models
- 5mm high-impact composite construction – resists chipping and UV fading
- Gloss Brown finish custom-matched to factory color codes
- Factory-correct mounting tabs and hardware compatibility
- Streamlined profile to reduce turbulence and wheel spray
In addition, these mudguards perfectly complement other AMG-specific body elements, providing a seamless profile and protecting essential underbody and suspension components from grit, debris, and road salts.
Furthermore, this duo is engineered for both the Left Hand (LH) and Right Hand (RH) rear wheels. Therefore, you get balance, symmetry, and a true OEM upgrade—all critical in preserving the precise driving experience associated with Mercedes-Benz.
OEM vs Aftermarket: Why Original Wins
In contrast to aftermarket alternatives, OEM parts guarantee manufacturer-verified safety ratings and flawless compatibility. That’s especially true on a vehicle as technologically advanced as the Mercedes AMG G-63.
Aftermarket suppliers may tempt with lower prices, but these products often fall short on structural rigidity and color accuracy. For example, non-OEM mudguards can create gaps, introduce rattling, or discolor rapidly, disrupting both ride quality and the G-63’s iconic appearance.
- OEM parts arrive with full Mercedes-Benz backing for warranty claims.
- Consistent quality control guarantees trouble-free performance.
- Material strength and finish match all surrounding panels exactly.
- Engineered to interact perfectly with active and passive safety systems.
- Help preserve the factory VIN-matched look that drives resale value.
Similarly, approved Mercedes workshops always recommend OEM for collision repairs, upgrades, or preventive maintenance. Choosing original is a smart, long-term investment in satisfaction and peace of mind.
Installation Tips and Maintenance Best Practices
Moreover, the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Brown OEM A4638805703 A4638805803 comes pre-drilled and shaped for fast, precise mounting. This reduces installation time and minimizes the risk of panel misalignment.
However, always start by thoroughly cleaning the mounting area. Remove any existing dirt, tar, or rust to ensure maximum bonding and prevent future corrosion. Genuine mounting hardware included with authentic parts further streamlines the process.
If in doubt, let a certified Mercedes specialist handle the install. However, advanced owners with basic tools and the provided instructions can often complete the upgrade within an hour.
As a result, ongoing upkeep is straightforward. Simply wash with mild soap and a microfiber cloth to preserve the gloss brown finish. Avoid abrasive cleaners or high-pressure washers that could damage the surface or seams.
