Key OEM Parts Categories and Specifications
To understand why OEM components lead the market, let’s examine core categories and their main benefits for your Mercedes AMG G-63.

This set includes both left and right-hand sides for balanced style and robust coverage against rocks and debris.
Similarly, the Mercedes AMG G-63 Hood gloss Silver OEM A4638802700 imparts a bold, crisp look, complete with AMG’s proprietary gloss silver finish for breathtaking curb appeal. This component fits seamlessly with existing hood lines, giving the SUV a modern, factory-authentic presence.

OEM vs Aftermarket: Why Original Wins
In the aftermarket world, plenty of options exist. However, only genuine Mercedes AMG G-63 Front LH & RH Wheel Thread Mudguard Widening Matte Black OEM A4638805503 A4638805603 and related OEM parts bring real value for money.
As a result, original parts stand out for their tested fitment, true-to-AMG finishes, and built-in compatibility with vehicle systems. Comparatively, aftermarket alternatives often feature inconsistent paint, questionable plastics, and subpar tolerances.
Furthermore, using OEM body panels preserves the certified crash protection engineered into every AMG G-63. In contrast, non-original parts might compromise safety since they lack Mercedes-Benz testing and quality control.
Additionally, OEM installation supports long-term resale value. Dealerships and buyers always favor factory-spec modifications and look for the correct part numbers—especially on supercars and luxury SUVs like the AMG G-63.
- Engineered and tested to AMG factory standards
- Warranty protected and officially documented
- Flawless body color matching and surface finish
- No modifications or retrofitting needed
- Direct impact on resale value and buyer confidence
Meanwhile, owners who opt for non-OEM upgrades risk frustrating installation problems, a mismatched aesthetic, and even voided warranty claims for accident or corrosion issues involving the replaced parts.
Installation Tips and Maintenance Best Practices
Factory-spec panels and accessories are all about ease of use and longevity. Therefore, follow these steps to ensure a perfect result, whether you’re fitting new mudguard widenings, or that gleaming gloss silver hood:
- Verify each part number (such as A4638805503 or A4638802700) against vehicle VIN for compatibility.
- Clean and prep all mounting surfaces to avoid paint scratches or debris under new panels.
- Pre-fit components using factory bolt locations—OEM parts always line up without hassle.
- Tighten bolts/nuts to Mercedes-Benz torque settings for proper structural integrity.
- Test open/close action or wheel clearance before final tightening, especially for hood or mudguard upgrades.
Consequently, OEM accessories demand less ongoing attention. Wash using Mercedes-approved foams; avoid abrasive chemicals. Inspect for rock chips or minor scratches—touch up with OEM-approved paint for best results.
Meanwhile, always store removed factory originals in a safe, clean place for potential reuse if customizing further. This approach preserves both warranty and resale flexibility.
