The rear fenders of the Mercedes-Benz G-Class W465 play a similar role to the front fenders, combining protection, durability, and design elements that align with the vehicle's rugged, off-road capabilities. These fenders protect the rear wheel wells from dirt, debris, and damage while also contributing to the vehicle’s classic, boxy design. Given that the G-Class is often used in challenging environments, the rear fenders are built to withstand the elements and provide adequate clearance for off-road driving.

Key Features of the G-Class W465 Rear Fenders:

1. Material and Construction:
   • Like the front fenders, the rear fenders of the G-Class W465 are typically made from high-strength steel or aluminum. Steel fenders are common in earlier models and provide maximum durability, while later models may feature aluminum fenders, which help reduce weight without compromising strength or performance.
   • Plastic or composite materials may also be used in certain trim levels or as part of custom aftermarket options to offer additional weight reduction or flexibility in design.
2. Design and Aesthetic:
   • The rear fenders share the same boxy, angular design that gives the G-Class its distinctive look. These fenders are an essential part of the vehicle’s exterior design, contributing to its rugged and iconic appearance.
   • Flared edges are typically seen on the rear fenders, allowing for wider tires that are commonly used on off-road versions of the G-Class. This design provides both a functional and aesthetic benefit, helping to keep dirt and debris from splashing onto the side of the vehicle.
   • The fenders are designed to integrate seamlessly with other body panels, such as the quarter panels, rear bumpers, and tailgate, ensuring a cohesive and strong exterior structure.
3. Protection and Durability:
   • The rear fenders are built to protect the vehicle from road debris, rocks, mud, and other environmental elements that could cause damage during off-road activities. The strong materials used in their construction ensure that the fenders can absorb impacts and shield critical parts of the vehicle.
   • Corrosion resistance is an important consideration for the rear fenders, especially in areas where the vehicle may be exposed to moisture, mud, and salt (in coastal regions or during winter months). Galvanized steel and protective coatings are often used to prevent rust and corrosion over time.
4. Wheel Clearance:
   • The rear fenders are designed with enough clearance to accommodate larger, off-road tires. This is especially important for models that are intended for rugged terrain, as the larger tires are often used for better grip and handling in off-road conditions.
   • For those who choose to modify their G-Class W465 for off-road adventures, the fenders may have additional clearance to fit wider or larger tires without rubbing against the body during turns or while the suspension is compressed.
5. Off-Road Capability:
   • As the G-Class is a vehicle designed for extreme off-road conditions, the rear fenders are built to handle the tough environments that the vehicle may encounter. This includes potential impacts from rocks, branches, and other obstacles when driving through rough trails, forests, or rocky landscapes.
   • Reinforcements may be built into the rear fenders for added protection, including additional plastic inserts or rubber molding to absorb impacts and reduce damage to the fender surface.
6. Damage Repair and Replacement:
   • If the rear fenders become damaged, they can often be repaired through standard auto body repair methods. Small dents or scratches might be treated with paintless dent repair (PDR), while more significant damage (such as deep dents or cracks) may require a full fender replacement.
   • OEM replacement fenders (Original Equipment Manufacturer) are available for those looking to restore the vehicle to its factory specifications. For those looking for a more custom approach, there are also aftermarket fenders that offer different styles, materials, or finishes, such as wider fenders for off-road modifications.
7. Customization Options:
   • Some owners choose to customize their rear fenders to enhance both the off-road capability and aesthetic appeal of the vehicle. This might include:
     • Extended fender flares or wider fenders to accommodate larger tires or provide a more aggressive look.
     • Custom finishes, such as matte black, carbon fiber, or protective coatings to improve durability and appearance.
     • Mud flaps or splash guards attached to the rear fenders to prevent dirt and mud from splashing onto the vehicle or surrounding areas.
     • Off-road lighting mounts or other accessories integrated into the fenders.
8. Lighting Integration:
   • On some models, the rear fenders may feature provisions for auxiliary lights, such as reverse lights or turn signals, which are positioned to ensure proper visibility during off-road driving or in low-light conditions.
9. Ventilation and Cooling:
   • While the front fenders may have integrated vents for engine cooling, the rear fenders typically don’t have similar vents, as their main purpose is to provide clearance and protection for the rear wheels and the vehicle’s body. However, some custom modifications may include added vents or heat shields if the vehicle is fitted with powerful engines or additional off-road accessories.

Conclusion:

The rear fenders of the Mercedes-Benz G-Class W465 are vital components in maintaining the vehicle's rugged durability, off-road readiness, and distinctive appearance. They are designed to handle harsh conditions, provide protection against debris, and ensure sufficient clearance for off-road tires. Constructed from durable materials such as steel or aluminum, they contribute to the vehicle’s long-lasting performance, whether on or off the road. With the option for customization and repair, the rear fenders can be tailored to suit the needs of the driver while preserving the G-Class’s iconic look and functionality.
