Buying Guide
What should I consider when choosing fenders with backs?
- Wheel size compatibility: Most options cover 14″-16″ wheels. Verify your tires’ diameter to avoid stretching.
- Back attachment method: Some backs are welded; others use separate plates. Choose based on whether you prefer weld-on or bolt-on installation.
- Material and finish: Steel with rust protection is common. Diamond plate adds durability and style; consider galvanizing or electrophoretic coating for marine use.
- Single vs. tandem axles: Tandem setups may require longer backs; ensure the backs align with your trailer geometry.
- Installation ease: Pre-cut or ready-to-weld backs can simplify the process, especially for first-time projects.
