Key OEM Parts Categories and Specifications

Body & Trim: Widened Mudguards and Spare Wheel Cover

Take a closer look at the Mercedes AMG G-63 Rear LH & RH Wheel Thread Mudguard Widening Gloss White OEM A4638805703 A4638805803. These mudguards are precision-molded in collector-grade Gloss White, perfectly following factory arch extensions. They widen your track profile for a muscular stance, channel road debris away from the body, and fit like a glove with zero modification required. Their UV-resistant finish ensures long-lasting brilliance, blending seamlessly with the G-63’s paint code.

Similarly, the Mercedes AMG G-63 Spare Wheel Cover Silver OEM A4638981700 provides a tough, weather-sealed barrier for your spare. It features the authentic three-pointed star badge, high-gloss silver finish, and exact engagement with the factory bracket; no rattles or leaks here.

Front Lower Bumper: Function and Flair

Furthermore, the Mercedes AMG G-63 Front Lower Bumper Gloss Silver delivers high-impact resistance and premium style. The bumper integrates seamlessly with active safety sensors, parking assist, and underbody protection. Only the factory part lines up with your G-63’s original spec for crash safety and aesthetic perfection.

Performance Upgrades: Brabus G700 PowerXtra B40-700 Genuine

Meanwhile, the Brabus G700 PowerXtra B40-700 Genuine is the only power kit approved by both Brabus and Mercedes for the AMG 4.0L V8. This kit safely boosts output to 700 HP, upgrading the ECU, turbo electronics, and intake systems using factory-style harnesses. As a result, it keeps warranty protection intact while turning your G-63 into a super-SUV rocket ship. Unlike generic remaps, OEM/Brabus kits are software-checked and won’t void compliance for GCC specifications.

• Body: Mudguards, bumpers, wheel covers — for fitment precision
• Performance: Genuine Brabus PowerXtra upgrade — for horsepower and reliability
• Safety systems: Sensors, electronics — factory integrity maintained
• Paint and trim: UV, corrosion, and heat-tested to Mercedes-Benz standards

OEM vs Aftermarket: Why Original Wins

Consequently, aftermarket components often lack the development and strict QC Mercedes enforces. Aftermarket mudguards may use cheaper plastic, never match the color, or misalign with mounting points—resulting in rattles or paint damage. Only the OEM A4638805703 A4638805803 mudguards preserve the iconic G-Class look and structural fitment.

In contrast, only the OEM spare wheel cover like A4638981700 locks securely, resists corrosion, and perfectly displays your badge of honor—aftermarket units expose your tire to weather and theft.

Moreover, true power upgrades require deep engineering. Brabus and Mercedes collaborate on kits like the G700 PowerXtra B40-700 Genuine to guarantee safe increases in power, emissions, and gearbox mapping. Off-brand tunes may void warranties or trigger limp mode. OEM upgrades, however, protect your investment both in fun and finance.

1. Fitment accuracy: bolt-on, zero custom work needed
2. Material quality: tested plastics, paints, and metals
3. Resale protection: factory codes and traceability for future buyers
4. Warranty integrity: no arguments at the dealership
5. Peace of mind: drive as Mercedes intended

Installation Tips and Maintenance Best Practices

Thus, always reference your official G-63 service manual when installing OEM body parts or upgrades.

Meanwhile, always clean new components before mounting. For the Mercedes AMG G-63 Spare Wheel Cover Silver OEM A4638981700, lubricate the gasket and fasten evenly for a watertight seal.

In addition, keep records of purchase and installation. This supports your warranty and enhances resale value. Ask your installer to scan part numbers, so everything ties back to genuine Mercedes or Brabus stock.
