Why OEM Parts Matter for Other Other
When you drive something as iconic as a Mercedes-AMG G-63, only true OEM parts maintain the integrity, safety, and value you deserve. After all, these SUVs set the global benchmark for off-road power wrapped in five-star luxury.
Similarly, using third-party or aftermarket body parts, even on less visible areas, can compromise both today’s performance and tomorrow’s resale appeal. For example, any expert will tell you that genuine Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Silver OEM A4638805703 A4638805803 parts deliver stronger, more accurate fitment compared to even high-quality imitations.
In addition, authentic G-Class mudguard widenings are specifically engineered for your model’s geometry and clears both warranty and safety requirements from Mercedes-Benz headquarters. That means they protect your investments—and ensure your G-63 looks factory-fresh, year after year.
Key OEM Parts Categories and Specifications
The rear wheel thread mudguard widening kits—available in stunning gloss silver or eye-catching orange finishes—are structural, load-bearing exterior upgrades. Crafted for the Mercedes AMG G-63, part numbers A4638805703 (LH) and A4638805803 (RH) deliver maximum coverage and an authentic AMG stance.
Furthermore, these parts feature:
- Exact ABS thermoplastic compound as the factory original
- Painstaking precision for perfect alignment and body gap consistency
- Corrosion-resistant hardware designed for real-world luxury driving

Therefore, both Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Silver OEM A4638805703 A4638805803 and Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Orange OEM A4638805703 A4638805803 remain the only way to sustain true AMG strength and beauty in your G-63.

Engineered Compatibility
These OEM parts are compatible with all G-63 W463 models (2019 and up), ensuring you get the perfect fit and unrivaled integrity. No tweaks, no drama—just bolt on and go.
OEM vs Aftermarket: Why Original Wins
Aftermarket alternatives might tempt you with lower prices and bold claims. However, the reality usually falls short—especially with a model as engineered as the G-63. Aftermarket widenings rarely match the exact compound, UV-resistance, or shape precision you get from genuine OEM parts.
For example, only the factory Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss Silver OEM A4638805703 A4638805803 comes pre-finished in the exact color and with all necessary Mercedes-specific mounting hardware. In contrast, aftermarket options often require adaptation, risking gaps or damage to surrounding paintwork.
Consequently, fitting OEM preserves both visual perfection and structural safety. Moreover, Mercedes-Benz only honors warranty claims if your parts maintain original design and material specs.
Five Reasons to Stick With OEM G-63 Parts
- Guarantees compatibility for the specific W463 platform
- Maintains factory-approved warranty and service coverage
- Preserves long-term resale and collectability
- Reduces installation complexity—no modifications required
- Authentic AMG visual flair with robust physical protection
Installation Tips and Maintenance Best Practices
Installing OEM mudguard widenings is straightforward if you have basic tools and mechanical confidence. However, professional installation is always advisable for a perfect fit and lasting finish—especially on a premium model like the G-63.
To get it right, follow these best practices:
- Carefully inspect and prepare mounting surfaces—no dust, no oil, no rust
- Match each mudguard to its respective side (LH: driver, RH: passenger in LHD markets)
- Always use Mercedes-supplied fasteners and torque to specification
- Test door and wheel clearance before final tightening
In addition, regularly clean your mudguards with a pH-neutral car shampoo. Avoid harsh chemicals or abrasive cloths, which can compromise the gloss or orange finish.
Furthermore, check mounting points every few months—especially if you enjoy off-roading—in order to prevent vibration-related loosening or wear.
