Buying Guide
- Material matters: Aluminum fenders save weight and resist corrosion, but check thickness and alloy type to ensure durability for heavy-duty use.
- Fit and coverage: Measure wheel diameter and axle spacing. Full-radius or long-drop fenders provide greater coverage; flat-top or quarter fenders may suit smaller or lighter trailers.
- Mounting style: Some fenders require separate brackets or hardware. Consider bolt-on versus weld-on options and plan for compatible mounting hardware.
- Intended use: For tandem axles, consider fenders designed for tandem fits and styling that complements your trailer’s design.
- Weather and environment: If you operate in salty or humid climates, aluminum is generally preferable to reduce rust; stainless steel options exist but may be heavier or pricier.
- Installation and maintenance: Look for fenders with clean mounting surfaces and compatible hardware; verify whether replacement brackets are needed for older trailers.
