2. Rear Fenders
Rear fenders are located over the rear wheels and serve similar functions to front fenders, albeit with considerations for the vehicle’s rear design and aerodynamics:
- Protection: Rear fenders protect the rear wheels from road debris and environmental elements, ensuring the vehicle remains clean and minimizing damage to the bodywork.
- Styling: Like front fenders, rear fenders contribute to the vehicle’s aesthetic appeal, integrating with the rear bumper and other components to create a cohesive design.
- Cargo Area Protection: In trucks and SUVs, rear fenders may extend further to protect the cargo area from debris and enhance the vehicle’s off-road capabilities.
3. Flare Fenders
Flare fenders, also known as wide-body fenders or wheel arch extensions, are designed to extend outward from the vehicle’s body. They serve several distinct purposes:
- Enhanced Wheel Coverage: Flare fenders provide additional coverage over wider wheels and tires, particularly in vehicles equipped for off-road use or performance driving.
- Style and Customization: These fenders are often used to give vehicles a more aggressive appearance, accommodating larger wheels and enhancing the vehicle’s stance.
- Protection Against Debris: By extending beyond the standard bodyline, flare fenders offer increased protection against mud, rocks, and other debris encountered during off-road adventures.
4. Quarter Panel Fenders
Quarter panel fenders are integrated into the rear quarter panels of the vehicle and play a crucial role in both protection and design:
- Body Integration: These fenders seamlessly blend with the vehicle’s rear quarter panels, contributing to the overall aesthetics and structural integrity.
- Crash Protection: In the event of a side impact or collision, quarter panel fenders help absorb and distribute impact forces, protecting passengers and minimizing damage to critical components.
