Buying Guide: Key Purchase Considerations
- Wheel size compatibility: Most options cover 14″–16″ wheels. Confirm your wheel diameter before buying.
- Back plate vs. integrated back: Choose back plates for flexible placement or pre-mounted backs for quicker installation.
- Material and finish: Steel fenders offer durability; look for rust-resistant coatings (electrophoretic or painted finishes) for longer life.
- Welding vs. bolt-on: Weld-on backs provide a secure mounting but require welding; bolt-on or pre-assembled backs offer simpler installations.
- Trailer type: Single-axle vs. tandem-axle needs influence back design, length, and mounting method.
- Protection level: Heavier gauge steel and full-coverage designs reduce debris impact and road debris contact with tires and frames.
