Mercedes-Benz GLS Body Kit Review — Installation & Cost

Enhance Your Mercedes-Benz GLS with a Stylish Aero Kit

Many Mercedes-Benz GLS 400d owners consider exterior upgrades to give their large SUV a more imposing and refined presence. One popular modification is the installation of an AMG-style vertical grille, often referred to as a "body kit" or "aero kit" in the context of exterior dress-up. This upgrade can significantly enhance the vehicle's front-end aesthetics, adding visual depth and emphasizing the GLS's already substantial stature. The goal is to achieve a look that is both luxurious and sporty, akin to a factory option but with a distinctively personalized touch.

The Benefits of a Vertical Grille Upgrade

Replacing the stock grille with a vertical bar design dramatically improves the vehicle's first impression. The sharp, vertical lines create an illusion of greater width and a lower stance, contributing to a more stable and aggressive appearance. This modification is a highly effective way to elevate the already premium image of the Mercedes-Benz GLS 400d, making it stand out with a sportier and more sophisticated vibe. The integration is designed to be seamless, ensuring the new grille complements the vehicle's overall design language.

Seamless Installation and Integration

The process of upgrading to a vertical grille involves a direct 1:1 replacement of the original grille. This method preserves the vehicle's factory integrity while allowing for a significant design transformation. A precise 1:1 replacement ensures minimal gaps or misalignments after installation, resulting in a clean, factory-perfect finish. Crucially, these kits are designed for compatibility with the various sensors and cameras found on the front of the GLS 400d. Using high-quality, compatible parts ensures that all safety and driver-assistance features continue to function without interruption. This is vital for maintaining safe driving performance, making professional installation by experienced technicians highly recommended.

Installation process:

1. Carefully remove any surrounding trim pieces near the original grille.
2. Detach the stock grille assembly.
3. Position and secure the new vertical grille, ensuring a snug fit.
4. Reinstall any removed trim and verify all sensor connections are properly seated.
5. Conduct a final inspection for fitment and alignment.

Cost and Time Investment for Your GLS Body Kit

The total body kit cost for a Mercedes-Benz GLS 400d can vary based on the specific grille style (e.g., AMG-style, genuine parts), brand, and the installation location. In South Korea, the typical cost for the part and labor often starts in the range of 300,000 KRW (approximately $220 USD, subject to exchange rates). For a precise quote, it's best to consult directly with a service provider after they have assessed your vehicle. The installation itself is generally a straightforward process, usually completed within 1 to 2 hours, making same-day completion common. This relatively short timeframe is due to the direct replacement nature of the upgrade.

Durability and Maintenance

Vertical grille upgrades are typically made from durable materials designed for longevity, often requiring minimal specific maintenance beyond regular vehicle washing. The parts themselves are generally considered to have a very long lifespan, often lasting for the life of the vehicle under normal conditions. The primary concern during installation is ensuring a perfect fit to avoid issues like rattling or misalignment over time. Proper installation by a professional is key to long-term satisfaction and durability.
