Buying Guide
Key considerations when choosing aluminum tandem fenders:
- Material and finish: Aluminuм premium for corrosion resistance; diamond plate grades offer extra durability, but smooth finishes can be lighter and easier to clean.
- Size and tire compatibility: Verify tire diameter (13″, 14″, 15″, 16″) and ensure the fender coverage matches your wheel wells to avoid gaps or interference.
- Mounting method: Some fenders include back lips and require hardware; others assume welding to the frame. Plan for your trailer’s mounting approach and frame thickness.
- Profile style: Teardrop shapes reduce wind resistance and add style, while diamond plate looks rugged and gives extra surface protection against dings.
- Local regulations and visibility: Some regions have guidelines for trailer reflectivity and fender coverage—confirm compliance with your area.
- Pack quantity: For tandem trailers, a two-pack can simplify symmetric installation and spare parts planning.
- Weight considerations: Aluminum is lighter than steel; check overall trailer weight distribution after installation to maintain balance.
