Buying Guide
- Fitment range: Confirm wheel size (18″–19.5″ or 19.5″–24.5″) and dual rear wheel configuration to ensure compatibility with your truck model.
- Material and durability: Polymer fenders offer lightweight protection, while stainless steel options provide long-term corrosion resistance. Consider the environment and maintenance needs of your fleet.
- Installation: Some kits include mounting brackets and hardware, while others require separate brackets. Check if the mounting system aligns with your trailer frame and existing hardware.
- Coverage and clearance: Look for fenders with sufficient width and depth to shield tires and prevent spray. Ensure clearance with tires, springs, and suspension components.
- Aesthetic and maintenance: Black finishes blend with most trucks; stainless options stay cleaner with less maintenance. Consider ease of cleaning and impact resistance in rough service areas.
- Weight and impact on fuel economy: Heavier metal fenders can add weight; polymer and lightweight stainless options help minimize added mass while maintaining protection.
- Warranty and brand support: Choose recognized brands with readily available replacement parts and mounting hardware in case of wear or damage.
